Sarah Jane Smith

Sarah Jane Smith, occasionally rendered Sarah-Jane Smith, was an investigative journalist who travelled with the Doctor in his third and fourth incarnations. She reunited with him in his tenth incarnation and had adventures with him and his eleventh incarnation. Sarah Jane met nine of the Doctor's incarnations in total: those already mentioned and the First, Second, Fifth, Seventh, and Eighth. Due to her experiences with the Doctor, she was entrusted with the task of protecting Earth from hostile extraterrestrials and helping peaceful aliens. She shared these adventures with her young companions/surrogate family.

Infancy
Sarah Jane Smith was born in May 1951 in the village of Foxgrove (TV: The Temptation of Sarah Jane Smith) under the astrological sign of Taurus. (TV: Secrets of the Stars)

On 18 August 1951 her parents, Barbara and Eddie Smith, abandoned her in her pram and drove off in their car to protect the world from the Trickster. The Trickster had nearly tricked the adult version of Sarah Jane into allowing him to manifest and then conquer Earth. A few minutes later on a country lane, Eddie and Barbara collided with a tractor and were killed.

Sarah Jane was raised by her aunt, Lavinia Smith, a virologist. (TV: The Temptation of Sarah Jane Smith) She may have been close to her uncle, Africana. (PROSE: The Curse of Kanbo-Ala)

Childhood to adulthood
Young Sarah Jane developed a fear of clowns because of an old clown puppet that had belonged to her Aunt Lavinia.(TV: The Day of the Clown) When Sarah Jane was five years old, (PROSE: The Day of the Clown) it hung in her bedroom and stared down at her as she slept. It seemed to move in thunderstorms. Later in her life, Sarah Jane learned it had been manipulated by the Pied Piper to induce coulrophobia in her for their future encounter. This fear stayed with her for most of her life. (TV: The Day of the Clown)

When Sarah Jane was about eight years old she lived in Wolfenden together with her Aunt Lavinia. There she also got to know the scientist Eddison Clough, who was a good friend of Lavinia. However, the alien Mrs Hendrick stole Sarah Jane's and Lavinia's memories. Sarah Jane did not remember that she had been in Wolfenden. She did not even recognize that some of her memories were missing until Eddison wrote her a letter and explained to her that he had found several pictures of Lavinia, Sarah Jane and himself in Wolfenden. Eddison has lost his memories of Sarah Jane, Lavinia and Wolfenden as well. Even though Sarah Jane never regained her memories, she saw several photos of her and Lavina's time in Wolfenden from Eddison. One of them shows Lavinia and Eddison Clough, another one shows Sarah Jane and Lavinia. (AUDIO: The White Wolf)

When she was nine, Sarah got into a fight with a young boy next door after he broke her Christmas present, a tape recorder. She retaliated by punching him and stealing his action man. For this, she went without Christmas dinner and was forced to stay in her bedroom as punishment. (PROSE: UNIT Christmas Parties: Ships that Pass’’)

In November 1963, Sarah Jane went on a day trip to London with her aunt. While Lavinia was buying sweets for her, Sarah Jane explored a junkyard and saw a police box there. After returning to her aunt, they walked by the junkyard and she caught a glimpse of a young girl entering it. (PROSE: Playtime) Sarah attended Church of England services as a child. (PROSE: ‘’The Discourse of Flies’’)

In 1964, Sarah Jane had already decided to become an explorer, a famous scientist or a journalist. She wanted to explore the world. She wanted to see everything there was to see and more. Her best friend Andrea Yates told her that women couldn't become journalists but Sarah Jane believed that the world was going to change and that soon women could do anything that men could. Sarah Jane was a good student. She got top marks in every class. Sarah Jane thought she was such a good student because she kept reading books like An Unexpurgated History of the Universe. (PROSE: Whatever Happened to Sarah Jane?) She studied General Science at school, giving her teacher Miss Prosser the nickname “Old Prodnose”. (PROSE: ‘’Island of Death’’)

Still a student, she met aspiring TV star Katy Pickering at a freshmen party and the pair soon became lifelong friends. (PROSE: ‘’Moving On’’)

On 13 July 1964, Sarah Jane was on a school outing with Andrea. Messing around in an area cut off to the public, Andrea slipped off a pier to her death, despite Sarah’s attempts to grab her hand. The Trickster later altered this event to create a timeline in which Sarah Jane died rather than Andrea. Many years later, this doomed the planet Earth. In the normal timeline, the event traumatised but changed Sarah, impressing on her the importance of life. She never forgot Andrea. She also met one of her future companions, Maria Jackson, due to Krislok's blunder and was given a vague warning about Andrea's death before being taken hostage again. Memories of this may have been why Sarah Jane later gave Maria the Puzzle box decades later in her life. (TV: Whatever Happened to Sarah Jane?)

Sarah fenced for her school team. (PROSE: Housewarming) She had two childhood friends called Billy and Julie. (PROSE: Managra)

In 1971, Sarah visited the Sistine Chapel on a tour. (PROSE: Managra)

When Sarah Jane was a little older than eighteen, she was studying at university. One day she was sitting at a large lecture hall listening to her favourite professor Edward Sheppard. Professor Sheppard talked about his favourite subject: the power of the press. He asked the young Sarah Jane what she would do if she found out something that was a threat to national security. Sarah Jane replied that she would publish the story, as a good journalist always had to reveal the truth. She said she would not care about the consequences. Sheppard replied that it might put a spy and his family in danger. He asked her if she would still publish the story if it would put innocent lives at risk. Sarah Jane replied that she had to think about that. Sheppard said that he sincerely hoped so. (AUDIO: Judgement Day)

Sarah began doorstepping when she was nineteen years old. (TV: Goodbye, Sarah Jane Smith) When she began in journalism, her editor was Lionel Carson. He had romantic feelings for her that she did not reciprocate; despite this, Sarah Jane remained fond of him. (TV: The Man Who Never Was) At some point in her early career, Sarah was mentored by James Stevens. (PROSE: Who Killed Kennedy)

Five years prior to meeting the Doctor and UNIT, Sarah was in a relationship with a Royal Navy officer named Sammy Brooks, who had red-gold hair. They split when he was given command of the Cuffley. (PROSE: Island of Death)

First meeting with the Doctor
While working for Metropolitan magazine, Sarah posed as her aunt (who was away in the United States at the time), an accomplished virologist, to infiltrate a UNIT-controlled facility where scientists had gone missing. She met Brigadier Lethbridge-Stewart and UNIT's unpaid scientific advisor, the Third Doctor, who was also using an alias- the name "John Smith". The Doctor quickly cut down her fake identity and sparked her willingness to take initiative and impress him. Once Professor Rubeish disappeared, she peered inside the Doctor's police box, which he claimed housed his equipment, hoping to find him hiding inside. Instead, she was stunned to discover that it was bigger on the inside. When the Doctor piloted his ship into the past, Sarah Jane had no choice but to stow away in his TARDIS. The Doctor was displeased by her intrusion but quickly took a liking to Sarah when she displayed how crafty, cunning, and resourceful she could be. The Doctor warmed up to Sarah and brought her back to Earth safely. (TV: The Time Warrior) She was roughly twenty-three at this time, by her own account. (TV: Invasion of the Dinosaurs)

With the Third Doctor
Sarah Jane travelled to 13th century England. She got embroiled in a conflict with a robber baron and a robot knight, believing the Doctor to be a key perpetrator in these events until he proved his good nature to Sarah. Sarah gladly protected the Doctor's life from endangerment after he revealed himself as UNIT's advisor, and helped him concoct several ways to deter an attack on the Lord Edward of Wessex's castle, such as constructing dummies, smoking mixture, and sleeping potion. She watched him respond in protest to the threats posed to the course of human history, and undue use of technology from a future long beyond the Middle Ages. She helped to defeat a Sontaran called Linx who had kidnapped the scientists at the facility to this timezone. Linx requested the assistance of the warrior Irongron to provide repairs to his damaged scout ship. Sarah took a chance to drug Irongron's food, a commodity he prided greatly as a self-proclaimed king. The potion made Irongron's men pass out, save for Irongron himself, who resisted the narcotic and accused Linx of betrayal. Irongron was killed by Linx before he could swing his sword at the Sontaran, but Lord Edward's archer, Hall, shot Linx in his probic vent with a bolt, killing him. As he died, Linx triggered the launch mechanism of his ship, resulting in a huge explosion as the rockets fired. Sarah and the Doctor fled Irongron's castle before it was swallowed by the force of the liftoff blast, and set off for Earth, where the Doctor intended to return her home safely. (TV: The Time Warrior)

A large cloud of deadly gas nearly destroyed Earth, but the Doctor discerned that it was not natural, but was an attempt by the Zirconians to invade Earth. He and Sarah used the satellites of Earth to set off an explosion to destroy them. (COMIC: Doomcloud)

The Doctor and Sarah accidentally travelled into a parallel Earth where they encountered human criminal versions of themselves. They escaped by travelling to a primitive Earth, where they left their counterparts, returning home. (COMIC: Who's Who?)

The Doctor, Sarah, Jeremy Fitzoliver and the Brigadier went to Space World, a new amusement park, to investigate a death that had occurred nearby. The park was run by Naglons from the planet Parakon disguised as humans. They wanted to hypnotise the humans to do their bidding. The aliens left Earth, but not before they captured Sarah and Jeremy. Sarah put up resistance and discovered that her captors were too aggressive for either her or Jeremy to successfully make an escape. The Doctor and the Brigadier travelled to Parakon to retrieve them, and the group later helped to foil a devious plot employed Freeth, chairman of the Parakon Corporation to get rich by waging war on other worlds and use the fallen victims of these battles as fertiliser for rapine, a very valuable commodity that would make him highly wealthy. (AUDIO: The Paradise of Death)

Sarah was eager to come back to Earth, expecting the Doctor to set the TARDIS's course to the scientific research centre. The Doctor saw no point in going back there with the suspicious activities resolved, instead aiming to land in UNIT HQ, but he got the coordinates a little off, finding himself in an empty park. The Doctor and Sarah arrived in 1970s London to find it had been evacuated because of dinosaurs. The dinosaurs were brought to London by a time machine in a plan to revert London and the entire world to a pre-technological level, which would undo the existence of all living things around at the time. Sarah tried to interview Charles Grover, but when she got too nosy, he kidnapped her and placed her on a "colony ship", peopled by individuals who thought they were heading for a new life; Sarah convinced some of the crew that the "spaceship" was fake and was able to escape. The Doctor reversed the polarity of the time machine, causing Grover and his accomplice, Professor Whitaker, to accidentally send themselves on a one-way trip to the pre-techological era.

Unfortunately, Sarah would have to face the departure of a friend at UNIT, Captain Mike Yates, who was convinced to join the cause of the Operation Golden Age group and assist them, betraying his colleagues. When Yates saw the error of his ways, he quickly reconciled with UNIT, but had caused enough trouble and distrust that it signaled the end of his career with them. Lethbridge-Stewart prevented him from facing legal repercussions by arranging for him to have extended sick leave and a chance to resign quietly. (TV: Invasion of the Dinosaurs)

Desperate for a scoop, Sarah Jane used her authority at UNIT to break into the Ministry of Defence at Whitehall. She found information about the death of Dr John Smith, the alias of the Doctor, in 1950. Terrified that the Doctor was going to die, Sarah kept the secret to herself. However, the Doctor's investigation of a crash site soon led the pair back in time to the Isle of Wight, where Sarah witnessed the death of John Smith. Delighted that it was not the Doctor, she confessed all to him. (PROSE: Numb)

Mysteriously drained of all power en route to Florana, the TARDIS landed on the planet Exxilon. There, they encountered Marine Space Corps members seeking Parrinium, a cure for a space-plague. Sarah had her first encounter with the Daleks, who had also landed for the same purpose. The Doctor and the Daleks discovered the Great City of the Exxilons, a large city with a power-disrupting tower preventing technology from working. The Doctor sought to disrupt its functions and remove the power-disrupting facility. The Daleks ordered humans to place bombs around the city's central tower to destroy it. The city was destroyed, as was the Dalek spaceship. (TV: Death to the Daleks)

Trying again to travel to Florana, the Doctor and Sarah arrived at Cerulean, which was being attacked by missiles from the planet Sedna. The Doctor created a better barrier, but soon realised that Cerulean was in fact Neptune and Sedna was a tenth planet, yet to be discovered in Sarah's timeline. The aliens began to speak of peace and asked that the Doctor represent the planet Cerulean, but before he was able to, he detected another TARDIS about to crash into his. He left and indicated that the other time machine was a future version of his own. (PROSE: Neptune)

The Doctor and Sarah finally arrived on Florana in 5968, just as the Chelonian Empire was to sign a treaty with humanity. The Doctor was mistaken for one of the delegates and Sarah went sunbathing. She overheard two Chelonians discussing how one had poisoned the Emperor's drink. Sarah went to warn the delegates, but the guards would not let her pass. Noticing the Emperor's strange actions, the Doctor poured a bucket of water down his throat, thus removing the poison. The Doctor and Sarah left Florana for Earth. (PROSE: The Hungry Bomb)

The Doctor, Sarah, Jeremy, and the Brigadier travelled to San Stefano Minore and encountered ghosts crossing from Null-Space to Earth. (AUDIO: The Ghosts of N-Space)

The Doctor took Sarah to Peladon during the reign of Queen Thalira. At this point in Peladon's history, its feudalistic society had remained static despite the many decades since the planet's induction into the Galactic Federation, with the lower classes having access to neither socioeconomic progress nor to advanced technology. At the time the Doctor and Sarah arrived, the uneducated Pel miners were in the middle of a joint trisilicate mining operation with the alien and technologically sophisticated Federation. The miners, fearing enslavement by the Galactic Federation and faced with the sudden appearance of and attacks by their deity, Aggedor, took Sarah hostage in an attempt to acquire advanced weaponry through blackmail.

Sarah escaped only to be immediately recaptured (along with the Doctor) and thrown into a pit by the conservative Chancellor Ortron. Thalira then successfully commanded their release, Ortron having previously ignored her requests. Shortly thereafter, Sarah had a conversation with her about gender egalitarianism.

The ever more discontented miners soon disrupted trisilicate production and the Galactic Federation, fearing the loss of a vital resource during its current war with Galaxy 5, sent in the Ice Warriors to force the mining to recommence. Since this was the Ice Warriors' only apparent purpose in sending an army to Peladon, Sarah convinced the planet's leaders to address the miners' grievances about the lack of social progress. In return, they would resume mining and no force would be necessary.

However, when the Ice Warriors arrived, they took over the primitive Peladon anyway. They had incited the riots which caused the Galactic Federation to send them there by using advanced technology to deceive the miners into believing their god was punishing them. After they conquered the planet and are then finally rebuffed, Queen Thalira asked the Doctor to be the new Chancellor. He recommended Gebek, the miners' leader, for the newly vacated Chancellor position. Seeing that Thalira was appalled at the Doctor's suggestion, Sarah pointed out to her the similarities between class and gender disparities. (TV: The Monster of Peladon)

Sometime later, the Doctor and Sarah travelled to Peladon again, and fought Dalek]]s once again. (AUDIO: Glorious Goodwood)

The Faction Paradox altered the Doctor's timeline twice while Sarah Jane travelled with him. In one timeline, the Doctor died and did not regenerate on Dust. In another, the Doctor did regenerate, which should not have happened at that time and place. (PROSE: Interference - Book Two) Later, these events reversed, allowing history to take its natural course. (PROSE: The Ancestor Cell)

At Christmas, the Doctor and Sarah went to the Brigadier's Christmas party, but did not enjoy it. They went to New York, 1822, where they met Santa Claus. As they talked, they did not realise that they were being watched by Clement C. Moore, who then settled down to write "Twas the Night Before Christmas." (PROSE: A Visit from Saint Nicholas)

The Doctor and Sarah went to December 1952, where the Doctor discovered that poisonous smog was killing the citizens. He discovered that it was created by two Xhinns, a humanoid alien race who were usually peaceful. They wanted to cover their tracks. With help from local gangsters, he created a time bomb, which made their ship age to the point of disintegration. (PROSE: Amorality Tale)

Sarah Jane went to Goodwood Racecourse, West Sussex, for a horse race, unaccompanied by the Doctor, who was taking a metabolism test on the Brigadier's advice. She encountered Daleks, whom she stopped with help from the U.S. Cavalry. (AUDIO: Glorious Goodwood)

The Doctor and Sarah met a man named Isaac, a composer who later became the Doctor's companion. He was stalked by two grey figures and apparently committed suicide. The Doctor tried to investigate, but was stopped by the bowler hat Time Lord, who informed him that he had to wait until he encountered the events himself. (PROSE: An Overture Too Early)

The Doctor and Sarah were called back to Earth by Liz Shaw, the Doctor's former assistant at UNIT. The Brigadier was acting strangely, giving orders to reassign UNIT troops "in a haphazard, unpredictable manner". There had also been flooding occurring worldwide. When the Brigadier ordered the Tower of London to be sealed off and flooded, Liz finally decided he was unfit for duty and gave him a check up. The Doctor deduced that the Brigadier had been possessed by a Remoraxian, a species that wanted to flood the world to allow them to colonise. The Doctor built a de-remorator to remove the Remoraxian from the Brigadier.

The Doctor, Sarah, Liz and the Brigadier went to the nearby UNIT seabase along with Agent Paul of the CIA. There, the Remoraxian Prime was orchestrating its plot to flood the world. When the Remoraxian Prime sent the Doctor and the Brigadier to the bottom of the sea, Sarah and Liz saved them from drowning.

Discovering that the American government authorised the nuclear bombing of Great Britain to stop the threat, the Doctor was given 29 minutes to negotiate with the Remoraxians. After the Brigadier persuaded the Remoraxian Prime that the Americans would follow through with the attack, the Remoraxians left Earth, ending the storms, and Agent Paul called off the bombing.

A mysterious cloaked figure abducted Liz, Sarah and the Brigadier, leaving the Doctor a single message: "Say goodbye, Doctor." They were later saved by eleven of the Doctor’s incarnations when their kidnapper was unmasked as the Doctor’s future companion Adam Mitchell. (COMIC: Prisoners of Time)

The Doctor and Sarah then travelled to Hezrah, where the people worshiped the Eternal Machine, which would send chosen citizens to the stars. The Doctor revealed that the machine was actually an alien that would slowly touch and kill the citizens, in order to gain power. The creature's followers grew angry at the creature and set it ablaze, killing it. (PROSE: ‘’The Discourse of Flies’’)

At some point during her travels with the Third Doctor, they visited Bob Dovie at 59A Barnsfield Crescent in Totton, Hampshire on 23 November 1963. (AUDIO: The Light at the End)

At the request of Mike Yates, who had attempted to make amends for his betrayal of UNIT by becoming more spiritual and peace-loving, Sarah investigated a Buddhist meditation centre which was being influenced by the Eight Legs of Metebelis III. During her investigation, Sarah was accidentally transported to Metebelis III and was eventually captured by the Eight Legs and their human servants. After being rescued by the Doctor and returning to Earth, it was revealed that Sarah was under the psychic control of the one of the Eight Legs. Under the instruction of K'anpo Rimpoche, Sarah escaped the Queen's control by staring into a Metebelis crystal and focusing on the concept of her own freedom. After this, the Doctor journeyed to the cave of the Great One on Metebelis III to return the Metebelis crystal he had stolen, where his body was wracked by deadly radiation. While he was dying and his TARDIS was lost in the Time Vortex, Sarah Jane and the Brigadier awaited his return for three weeks. Sarah believed he had died, but the Brigadier kept faith. As the Doctor's TARDIS returned to UNIT HQ, he stumbled out and regenerated before them into his next incarnation. (TV: Planet of the Spiders, Robot)

With the Fourth Doctor
Immediately after his regeneration, the Fourth Doctor was put under the care of UNIT physician Harry Sullivan. While he began to adjust to his new incarnation, Sarah went off to investigate Think Tank following several incidents where a machine had been breaking into various places to steal parts for a disintegrator gun. It was here that Sarah had her first encounter with Hilda Winters, leader of the Scientific Reform Society, a group of radical elites trying to establish a new world order using Professor J.P. Kettlewell's greatest creation, Experimental Prototype Robot K1. K1 could think for himself and make his own decisions, but was programmed with the prime directive to never harm a human. Regardless, Kettlewell had lent K1 to the SRS after years of putting up with a society that refused to heed his warnings about environmental protection.

Sarah, the Doctor and Harry became involved in an investigation which resulted in a confrontation with the SRS and K1, with the help of Lethbridge-Stewart, newly-promoted Warrant Officer Benton and UNIT troops. Because Sarah showed kindness and sympathy to K1, it took a liking to her, and refused to harm her in any way. Despite the SRS's attempts to override its primary directive, K1's mind began to deteriorate from its conflicted morality. Kettlewell similarly faltered in his loyalties to the SRS, and tried to stop K1 from killing people. K1, in an act of confusion, killed his creator with the disintegrator gun built from the parts he stole. K1, no longer answering to a father figure, overcame an Oedipus complex and turned against the SRS. When the Brigadier used the disintegrator gun against K1, the robot instead grew to tremendous proportions and kidnapped Sarah.

In UNIT HQ, the Doctor and Harry worked on developing a metal virus that would dissolve the giant robot using Kettlewell's research. Arriving with the solution, he dumped it on K1, and the robot corroded away until nothing was left of him. After the robot and its power-hungry controllers were defeated, Sarah felt saddened by the loss of K1, thinking it could have been avoided. The Doctor offered her some comforting words, along with a jelly baby, his new favourite snack. Choosing to duck out of the formal rituals that came with his job at UNIT, the Doctor wanted a fresh start in his fourth incarnation, and planned to leave UNIT behind. Sarah agreed eagerly to continue travelling with the Doctor to other adventures in time and space. Although sceptical, Harry Sullivan went with them, when he caught the two about to depart and didn't believe the truth about the TARDIS. As the TARDIS dematerialised, the Brigader caught it just in time to watch it vanish and glumly faced the prospect of the Doctor ditching him, not yet aware two more of his personnel had followed suit. (TV: Robot)

Sarah's first trip with this Doctor was sidetracked when Harry interfered with the console controls. Instead of landing on the Moon as intended, the TARDIS materialised on Space Station Nerva far in the future, where humanity had been cryogenically suspended to await Earth's recovery from solar flares. The three of them quickly learned the space station had been robbed of its power supply, and as a consequence, its air supply. Sarah lost consciousness from the lack of oxygen, but slowly came to once the Doctor had fixed the power, reactivating the Nerva's oxygen generators. The Doctor and Harry unknowingly sat her down on a transmat chair, linked to the Nerva's hibernation systems, to recuperate. She was beamed to a tranquiller couch that lulled her to sleep, then put in stasis and transmatted to a cryogenic pod, outfitted in a crewmember's uniform.

After stumbling upon Sarah, the Doctor was unsure if he could revive her. Luckily, with power restored to the space station, the crew started coming out of cryogenic suspension, the first being Vira, the Nerva's level one medtech, to reawaken the rest of the crew. As more emerged from hibernation, one of them, Noah, was infected by an alien larvae on the space station and started transforming into a monstrous creature. The Nerva had been invaded by Wirrn, which posed a substantial threat to the return of humanity, in retalitation for their destruction of the Wirrn's breeding colonies in Andromeda. They wished to use the humans as food and incubators for their kind, and tampered with its innerworkings to stop the crew from being revived.

Noah, resisting conversion into a Wirrn, gave everyone a chance to escape, if they fled the Nerva on its sole transport ship and left the dormant humans to the Wirrn. When the group refused, the Wirrn cut the Nerva's power again. Sarah put forth a plan to hook up the ship's power supply to the space station. To make it work, a power cable was fed from the ship to the cryogenic chamber through a conduit, safe from the Wirrn. A job meant for a mechanical cable runner, which the Nerva lacked, Sarah, being small and nimble, elected to crawl through the vents while in radio communication with crewmember Rogin as he instructed her movements using a map of the conduit systems. However, Sarah misjudged the size of the conduits and kept getting stuck. Upon approaching the exit port for the cryogenic chamber, she heard the Doctor's voice nearby, but got trapped, causing her to panic.

The Doctor, tired of Sarah's "whining", suddenly quit coaching her through the vents and berated her as a useless, stupid, foolish girl only pretending to act tough, lacking the guts to back up her promises. Strongly enraged at the Doctor's insults, Sarah, blinded by her anger at him, stopped thinking about being stuck in the vent, broke free and scrambled to the exit with intent of coming after him. As the Doctor helped her out, she wrenched herself away from his arms and attempted to smack him in anger. However, the Doctor revealed he was actually very proud of her and simply used reverse psychology on her. Realising she had been "conned again", Sarah called the Doctor a "brute", before forgiving him, knowing he meant no insult to her character. With Sarah's plan successful, the Wirrn were lured into the transport ship by Noah, who retained his humanity and tricked the Wirrn into a suicide by making sure the rocket stabilisers were not set, destroying the vessel moments after liftoff. Rogin also sacrificed his life to send the ship into space, stepping in for the Doctor against his wishes when he tried to do so. On behalf of the space station, the Doctor went down to Earth with Harry and Sarah Jane to fix the relay. (TV: The Ark in Space)

The trio found the Earth appeared uninhabited at first glance, but soon encountered survivors of a group of GalSec human colonists that had been tricked into landing on the planet, experimented on and slowly killed off. Sarah was protected from a robot patrolling the fields for humans to capture by Roth, a straggler from the marooned crew. Roth kept them both out of sight, having escaped from an experiment. However, the robot did another sweep around the landscape and found them. It brought them to a familiar-looking ship, and the Sontaran Field Major Styre emerged. He had been sent to analyse the weaknesses of humans before the Sontarans invaded the barely populated planet. Sarah initially mistook him for Linx, since, hailing from a clone race, they looked almost identical. Roth, refused to be experimented on again and fled, but Styre immediately killed him with a blaster.

The Sontaran assessed Sarah's strengths and weaknesses. After noting she lacked military value, he decided to make her his seventh experiment- resistance to fear. Styre placed Sarah inside a force field, bound up with a device linked to her mind, which made her hallucinate her worst fears, such as snakes, the nearby rock cliffs caving in, and being swallowed up by mud. The Doctor found Sarah and disabled the torture device, but she had passed out from fright. Furious, the Doctor confronted Styre and called him an "unspeakable abomination" for tormenting her. Styre responded by shooting him, but the Doctor had a pocketed a door lock mechanism from the Nerva that deflected his blaster's discharge. Harry discovered both of them collapsed and was surprised to see the Doctor was actually unharmed, staying behind to help Sarah recover.

Once Sarah was awake again, the Doctor announced a plan to tire out Styre in a duel. Styre would return to his ship and let it re-energise him, which could be sabotaged. While the Doctor fought Styre, Sarah and Harry rescued several GalSec crewmembers from a gravity bar experiment. Then, as instructed by the Doctor, Harry stole the terullian diode bypass transformer from Styre's ship, which caused it to drain the life from Styre's body and explode. The Doctor then went to Styre's communication booth and bluffed the Sontaran Marshal he reported to from sending the invasion force to Earth, sparing the planet for the near future. He finally fixed the Nerva's transmat relay, letting the GalSec survivors beam to the space station. The Doctor, Sarah and Harry attempted to return to there themselves before the colonists, unaware of an outside force about to divert them from the Nerva Beacon. (TV: The Sontaran Experiment)

The transmat was intercepted by a Time Lord, pulling the Doctor, Sarah and Harry to the planet Skaro in its distant past. On behalf of the Time Lord race, the messenger sent them on a mission to intervene in the creation of the Daleks, giving the Doctor a time ring that would send him and his companions back to the TARDIS when it was completed. The Doctor was either to prevent it or to induce the Daleks to develop into less dangerous creatures. Sarah was captured by the Thals and put to work in a labour camp, under conditions that were guaranteed to kill off the workers after a while by having them move dangerous materials without the protective equipment to protect them from deadly exposure, with the Thals having fought for so long they were running out of supplies and had none to spare for prisoners. She made friends with one of her fellow prisoners, Sevrin, a Muto, who aided her in her escape and against the Daleks.

The Doctor and Harry found and rescued Sarah. However, the Doctor had learned the mad Kaled scientist Davros turned traitor to his own people by selling out the location of the Kaled Dome to the Thals and would have them bombed by a neutronic missile, since they opposed his plans to guide their war weapon-induced mutations into the Dalek species, which they disapproved of. Sarah and Harry, along with Sevrin, ran off to warn the Kaleds, but the Dome was bombed while they were en route through the wilderness of Skaro.

The Doctor feared his companions had been killed until they managed to reunite with him and inform him of what happened. While trying to infiltrate the bunker beneath the ruined dome, Sarah, the Doctor and Harry were all captured and tortured by Davros, who wanted to know the Doctor's foreknowledge of the Daleks' defeats so he could plan against them. The Doctor complied and Davros released his companions, and was soon overpowered by the Doctor momentarily. He had an opportunity to destroy the embryonic Dalek mutants and prevent any Daleks from existing, but though Sarah urged him to go through with blowing them up, the Doctor saw how fear of the Daleks had brought worlds together under noble reasons which otherwise never would have united and chose to let the Daleks survive. Sarah and Harry instead helped him capture Nyder, Davros's assistant, to turn the tables against him.

Davros released the first batch of Daleks he created to wipe out the Thals and any remaining dissidents among the Kaleds who disagreed with his plans to mutate them into such creatures of pure hatred, but soon learned they refused to obey anyone who wasn't a Dalek because of the way he programmed them, and watched them kill Nyder when he tried to shut down their production. Davros was soon struck down by his own creations as everyone else in the bunker fled for their lives. Although the Doctor was morally unable to commit genocide by destroying the entire race, he delayed the Daleks' advancement for 1,0000 years by helping the Thals bury them underground. Nearly losing the Time Ring that would let him leave Skaro, the Doctor finally managed to get himself, Sarah and Harry off the planet by using the ring. Sarah gave her best regards to Sevrin and the surviving Thals before leaving. (TV: Genesis of the Daleks)

After departing from Skaro, the Doctor, Sarah Jane and Harry became scattered across the Adelphine Cluster due to temporal disruption interfering with the time ring. However, they were eventually united by the interventions of the Time Lords, who also provided them with a new time ring. (PROSE: A Device of Death)

Using the time ring, the Doctor, Sarah and Harry set off for Space Station Nerva. But instead, they arrived on the Desolii, a famous ghost ship, where they encountered friendly robots, miscroscopic psychiatrists and ghosts. (PROSE: The Last Thing You Ever See)

After departing Skaro, the Doctor, Harry and Sarah Jane ended up on Space Station Nerva when it orbited Jupiter. While waiting for the TARDIS to catch up with them, the Doctor was involved with stopping a Cyberman attack on Voga, the planet of gold, an element they were highly vulnerable to. He Sarah Jane from the fatal bite of a Cybermat, which snuck up and attacked her. THe Doctor managed to transmat Sarah to Voga, which filtered the Cybermat's poison out of her bloodstream. Kellman, a traitor to the Nerva crew, was trying to lure the Cybermen to Voga, where they would be attacked by a missile waiting for them.

Sarah escaped the wrath of the native Vogans who disapproved of outsiders invading their secluded lifestyle, having fled to the innermost depths of Voga to avoid futher conflicts with the Cybermen after suffering repeated onslaughts by them in the past. She returned to Nerva, where she tried to spy on the Cybermen, but was caught and tied up on Nerva as the Cybermen tried to crash it into Voga. The Doctor stopped them from blowing up the station and the planet Voga and saved Sarah's life. The Vogan Vorus attempted a counterstrike with a missile, but the Doctor lured it away from the Nerva and into the fleeing shuttle of the Cybermen. His TARDIS at last managed to hone in on the Nerva and materialise, allowing the crew to go home to Earth, only to be greeted with a message from Brigadier Lethbridge-Stewart through the space-time telegraph the Doctor left him, indicating a grave emergency. (TV: Revenge of the Cybermen)

With the TARDIS still recovering from solar flare radiation, the Doctor took Sarah and Harry to 24th century Prague, where they visited a museum and discovered a dead body in one of the exhibits. The Doctor was accused of murder, but persuaded the police to allow him to take over the investigation. He and his two friends discovered nanoprobes had been in-bedded into the city, and further investigating soon led them to the killer. (PROSE: Nanomorphosis)

(PROSE: ‘’The Sinister Sponge’’)

When the Doctor constructed an Oscilliating Reverbretator Unit to make changes to the TARDIS, Sarah and Harry were transported onto a galleon in space, where they were taken hostage by space pirates. The Doctor managed to land the TARDIS before his companions were thrown into space. (COMIC: Avast There!)

During another trip into space, Sarah Jane was kidnapped by the Verulan, and the Doctor and Harry travelled to Earth, which the Verulans had planned to attack, and sought refuge at the home of Geoff Sinton and his family. The Doctor used the Sinton's TV to make contact with the Verulan war marshal, Kathnor. He tricked Kathnor into releasing Sarah, and later destroyed the Verulan ship once Sarah had escaped in the escape pod. (PROSE: The Last Broadcast)

The Doctor's body was stolen by Rascla, the twisted master of the planet Torm, who intended to unleash a virus onto Miltra B and ’leave it's galaxy vulnerable to attack. Whilst Rascle made plans to dominate the galaxy, the Doctor had secretly taken over Sarah Jane's mind, who, along with Harry, had been hypnotised into helping Rascla. The Doctor endured a brutal psychic duel with Rascla, and Rascle's spirit was destroyed, enabling the Doctor to reclaim his body and make sure Miltra B's galaxy was protected. (COMIC: The Body Snatcher)

Intending to take Sarah and Harry to Phenolyadron, the Doctor was puzzled when the TARDIS was diverted to the planet Peugross in the 37th century. Whilst there, the Doctor, Sarah and Harry discovered a human crew from Earth had mutated into Eye-Spiders, and were commanded by the Doctor's old friend, Xerxes Periopolos. The travellers reversed the mutation and repaired the rocket, so that the crew could return to Earth. (PROSE: The Eye-Spiders of Pergross)

In prehistoric South Africa, the trio were accused of summoning a legendary beast known as a Nandi bear to kill a tribesman. Captured by the tribe, they tried to prove their innocence by hunting the beast down. However, Harry disguised himself as “dupe” the beast and allowed the tribe to chase him back to the TARDIS. Assuring everyone they would deal with “the creature”, Sarah and the Doctor entered the TARDIS and left. (PROSE: ‘’To Kill a Nandi Bear’’)

When the Doctor was called back to Earth, Sarah Jane reunited with the Brigadier and Benton in Scotland. The Zygons were trying to bring the legendary Loch Ness monster under their control. During their investigation of attacks on oil rigs by the monster, a Skarasen, a creature native from the Zygon homeworld, Harry was grazed in the head after the Duke of Forgill's gamekeeper, the Caber, shot at him for trespassing. When UNIT found him and had him hospitalised, Sarah was attacked by a Zygon posing as a nurse and imprisoned. When he was rescued by the Doctor, her holding cell was gassed, forcing him to place her in a temporary trance to survive without oxygen. Later, she was attacked again by Madra, impersonating Harry, who fled and dove into a barn while running away, where he transformed and attacked her with a pitchfork, but stumbled while trying to reach for her from atop a haystack, fell over, and impaled himself.

Sarah later did research in the Forgill Castle and discovered a secret passage to a Zygon ship. There, she found Harry being held prisoner and freed him. They snuck back into the castle to reconvene with the Doctor and the Brigadier, who hatched a plan to free everyone held hostage on the Zygon ship and then cause it to explode. However, their leader, Broton, was elsewhere, luring the Skarasen to London with a trilanic activator, which it would destroy along with the target, the basement of Stanbridge House.

The Doctor found Broton and summoned UNIT soldiers to his aid. The Brigadier shot Broton to death and the Doctor fed the activator to the Skarasen, who then swam back to to Loch Ness. Sarah and Harry witnessed the creature rise from the River Thames before it fled and cause panic in the streets of London. After this incident and being shot, Harry had decided not to board the TARDIS again when the Doctor insisted on giving everyone a ride back to London when he went back to a Scottish plantation to retrieve his ship. Sarah bid goodbye to Harry, who wished to return to UNIT, and continued her adventures with the Doctor while the Brigadier had arranged a lift for himself, Benton and the Duke of Forgill by train. (TV: Terror of the Zygons)

On their way to UNIT HQ, Sarah found the TARDIS had landed on Zeta Minor instead. She immediately noticed the strange effects being there had on her person, comparing it to the soul being drawn from the body. Sarah and the Doctor were blamed by Controller Salamar for the deaths caused by the anti-matter creature and were close to being ejected into space when they were saved by Vishinsky, who seized control from the Controller. (TV: Planet of Evil)

The Doctor and Sarah Jane posed as Earth delegates on the planet Farrash, a dying planet that official Earth delegates took no interest in. During a public demonstration, Sarah was seperated from the Doctor and was saved by a group led by Fraal. Horrified to learn the group were experimenting on animals and that the Leader was sanctioning foetuses for his experiments, she re-joined the Doctor to stop a rogue robot from going on a killing spree. With the Leader dead, the duo encouraged the population to work together to find a way to save Farrash and left. (PROSE: Rights)

The Doctor next took Sarah to the circus to watch a performance by the great P.T Barnum. However, they lost the TARDIS to circus performer Benjamin, who planned to use the time machine as a new magic act called "the wondrous box", accidentally transporting the vessel back to various points in the circus's past. The Doctor managed to bring Benjamin to the present, and regained his TARDIS. (PROSE: The Wondrous Box)

While still trying to get back to UNIT, Sarah Jane encouraged the Doctor to resign from his position if he was getting tired of working for them. However, they were diverted to UNIT HQ in 1911 and ended up getting involved with stopping Sutekh from escaping his prison on the planet Mars. They succeeded in ageing the villain to death in mid-transfer to Earth. (TV: Pyramids of Mars)

Upon spotting a double decker bus at a manor house in 1764, Sarah Jane met another Time Lord, Iris Wildthyme, who's TARDIS was disguised as the bus.

On another mission for the Time Lords, the Doctor and Sarah were sent to destroy a spacestation that held the Bendriggan virus. However, they were accused of murdering a messenger and sentenced to death by Admiral Cosmicon, the Bendriggan commander. The Doctor proved their innocence by sending a message in Time Lord logic to a Bendriggan code expert, but winning their trust was short-lived when many Bendriggan's became infected.

After taking the alien back to its home planet and tipping it into a pit when it planned to conquer Earth, Sarah Jane and the Doctor returned to the TARDIS to continue travelling. However, she had become tired of how the Doctor barely paid attention to her emotional distress and threatened to leave to get his attention. (TV: The Hand of Fear)

Departure
After many trips with her, the Fourth Doctor received a summons to return to Gallifrey, his home world. As humans weren’t allowed on Gallifrey, she had no choice but to leave the TARDIS, although neither wanted to separate. Their final words to each other were pleas to not forget their time together. Standing in the street, watching the TARDIS dematerialise, Sarah realised that, in attempting to take her home, the Doctor had not only missed landing on Hill View Road, but had not landed in South Croydon at all. She remarked to a nearby dog, "He blew it," before walking off toward her new life. (TV: The Hand of Fear) Indeed, the Doctor had mistakenly left her in Aberdeen, Scotland. Sarah held onto the hope that the Doctor would return to her, and when he didn’t, she feared he may have died. (TV: School Reunion)

The 1970s
According to one account, Sarah encountered the Fourth Doctor again in 1979. (PROSE: Suitors, Inc.)

The 1980s
In 1978, the Doctor sent a crate to Sarah Jane, in care of her Aunt Lavinia on Hill View Road, in South Croydon. Sarah Jane had already moved out by that time and was travelling extensively, "never in one place long enough to lick a stamp," as Lavinia put it. Lavinia herself left the following year, and took the crate with the rest of her furnishings to the manor house she had purchased in Moreton Harwood, Gloucestershire, where it stayed in the attic for another two years. On 18 December 1981, Sarah Jane arrived for Christmas at Lavina's new home, only to find that Lavinia had left early for her American lecture tour, leaving Sarah Jane and Lavinia's new ward, Brendan Richards, to celebrate the holidays without her. The pair promptly opened the crate to discover K9 Mark III who explained that he was a gift from the Doctor, prompting Sarah to happily remark that he didn't forget. With the help of K9 and Brendan, Sarah Jane uncovered and stopped Moreton Harwood's murderous cult of Hecate. (TV: A Girl's Best Friend)

After this happened, Sarah, Brendan, Lavinia and K9 continued to investigate and stop other cults and witchcraft covens present in Britain. (PROSE: Powerstone, The Shroud of Azaroth, Hound of Hell, The Monster of Loch Crag, Horror Hotel, The Curse of Kanbo-Ala) After having a go at living in the Gloucestershire countryside (TV: A Girl's Best Friend), Sarah Jane and K9 soon moved to a semi-detached house in Camberwell. (PROSE: Harry Sullivan's War) Sarah Jane allowed K9 outdoors unattended, and their gate bore a "beware of dog" sign. (TV: The Five Doctors)

One morning, on her way out to catch a bus, circa 1983, Sarah Jane dismissed K9's sense of danger and declined to either stay home or take him with her. She was quickly swept up by the Time Scoop which removed her to the Death Zone on Gallifrey. There, she took part in the Games of Rassilon and reunited with the Doctor's third incarnation. She met the First, Second, and Fifth Doctors (though she was confused as to who the Fifth Doctor was, which the Third Doctor promised to explain later), and introduced herself to Tegan Jovanka. Sarah also had a reunion with the Brigadier and briefly met Susan Foreman and Vislor Turlough. (TV: The Five Doctors) She did not appear to recognise Susan as the former teenager whom she had briefly seen at the junk yard twenty years earlier. (PROSE: Playtime)

In 1983, Lavinia Smith sent Sarah and K9 to Egypt, where they investigated an incursion by Silurians. (COMIC: City of Devils)

Shortly after this, while investigating a story about the anti-bioweapons brigade in 1983, Sarah Jane helped Harry Sullivan to clear his name and stop an anarchist revolution. (PROSE: Harry Sullivan's War)

One account claimed that, following the Cyberman invasion, (TV: The Tenth Planet) Sarah Jane, as UNIT's official chronicler, phrased it as "the Aladdin's Lamp of applied technology," and wrote of it: "At one and the same time, the Cyberman invasion was both the greatest disaster and most astonishing blessing ever to have happened to the human race," since humans were able to salvage the abandoned Cyberships and make advances in space travel. (PROSE: The Power of the Daleks)

In 1987 Sarah Jane made an article about Francis Augur for the Metropolitain magazine. She later said that this wasn't one of her best works. She spent too much time exploring his passion for protecting the environment rather than focusing on his work as a doctor. In 2008 she met Francis Augur again. (AUDIO: The Glittering Storm)

The 1990s
By one account, Sarah Jane accompanied the Doctor's seventh incarnation to a jazz concert in the Royal Albert Hall and defeated an invasion of Earth by rogue members of the insectoid Kalik species. (COMIC: Train-Flight)

In the early 1990s, Sarah Jane, K9 and Mike Yates investigated a supposedly haunted house, and foiled a plot by the Master to kill the Doctor. (PROSE: Housewarming)

In 1995, Sarah Jane worked with the Brigadier to defeat the Great Intelligence, which had possessed Victoria Waterfield, another of the Second Doctor's companions. (HOMEVID: Downtime)

In 1996, with the Doctor's eighth incarnation's companion, Sam Jones, she fought human rights abuses and met a potential future husband, Paul Morley. (PROSE: Christmas on a Rational Planet, PROSE: Interference - Book One, Interference - Book Two)

In 1997, she assisted the Doctor's seventh incarnation against the Cortez Project in Hong Kong and died. (PROSE: Bullet Time) The Council of Eight had altered history by having Sarah die well before she should have done. Her death was undone by the Eighth Doctor's eventual defeat of the Council. (PROSE: Sometime Never...)

After Brendan returned from the University of Cambridge, (PROSE: Housewarming) he assisted Sarah and K9 in investigating a supposedly demonic pig spirit. When K9 became possessed by this spirit, Sarah worked out a way of exorcising it by electrocuting K9, defeating it. (PROSE: The Sow in Rut)

K9 began slowly breaking down and Sarah Jane was not able to repair K9's future technology. She did not show him to anyone else out of fear that revealing his technology could rewrite human history. Having essentially given up on being able to repair him, she relegated him to a cardboard box in her attic. (TV: School Reunion; PROSE: Moving On)

After K9 had completely broken down, Sarah began writing fiction based upon her adventures, and other companions she had met previously. (PROSE: Balloon Debate)

In 1998, Sarah was visited by her younger self, who was accompanied by the Fourth Doctor and Harry Sullivan. (PROSE: System Shock)

According to one account, by 1998 Sarah had married Paul Morley and taken his name. As "Sarah Jane Morley", she addressed the Nobel Academy in 1998. (PROSE: Christmas on a Rational Planet) By several other accounts, Sarah Jane had never been married before she met Peter Dalton; she lamented that, after travelling with the Doctor, no other man was able to compare, and she had grown old alone. (TV: School Reunion, Invasion of the Bane, The Wedding of Sarah Jane Smith)

Sarah Jane lost another family member in 1998 when her aunt, Lavinia Smith, died, (PROSE: Millennium Shock; TV: The Wedding of Sarah Jane Smith) and, sometime before this, Africana had passed away too. (PROSE: The Curse of Kanbo-Ala)

Changes
Over the years, Sarah Jane had grown more pacifist, and she chose to help the Earth by quietly opposing those aliens hostile to it and welcoming those who would befriend it. Her philosophy of alien contact stood in contrast to UNIT and the Torchwood Institute, whom she believed tended go in "all guns blazing". (TV: Invasion of the Bane, Journey's End) Her inheritance from Aunt Lavinia afforded her considerable freedom and resources. (TV: The Wedding of Sarah Jane Smith)

She continued to work as an investigative reporter after her departure from Planet 3 and her aunt's death. (AUDIO: Comeback) She was joined by fellow investigators Natalie Redfern and Josh Townsend. A conspiracy to destroy her career was initiated against her by her old enemy Hilda Winters, who intended to commit a vicious bio-terrorist attack and frame Sarah for it, but Sarah and her companions thwarted this. (AUDIO: Mirror, Signal, Manoeuvre)

During this period, Sarah Jane drove a red Volkswagen Beetle she called "Ethel," until it was blown up by her enemies. (AUDIO: Comeback)

Four years on, Sarah had become tired and morose, knowing she couldn't talk about her past with anyone and starting to think she'd imagined it. She also became involved in the machinations of the doomsday cult known as the Crimson Chapter of the Orbus Postramo, who believed in a four-hundred-year-old tome named the Book of Tomorrows, which claimed aliens would wipe out humanity in the year 2000 — and discovered that the tome made reference to her. (AUDIO: Buried Secrets) To her horror, she discovered the Chapter wanted to commit genocide so their prophecy would be fulfilled, and they believed she was the human herald of the alien apocalypse. While she prevented this, she was distraught to find out the Orbus Postramo and the Book of Tomorrows had been formed due to comments she'd made to Giuliano while travelling with the Doctor. (AUDIO: Fatal Consequences)

Following this and the discovery that her friend Josh was a cold-blooded killer for the rival White Chapter cult, she admitted she was lonely and wondered if the Doctor had left her on Earth for a specific task. Needing something to believe in again, she went on the world's first commercial spaceflight, which would pass a comet that the White Chapter had said would bring salvation, only for the flight to be sabotaged by the last Crimson Chapter acolyte, killing Josh and leaving Sarah with failing life support and a vision of something she felt she'd been searching for. NASA intended a rescue mission to save her. (AUDIO: Dreamland)

At some time Sarah moved to 13 Bannerman Road in Ealing, and established her home office in the attic. There, she hung photos of Brigadier Lethbridge-Stewart, Harry Sullivan, and herself with K9 Mark III. (TV: Invasion of the Bane) Also in the attic, she kept K9's remains in a cardboard box. (TV: School Reunion; PROSE: Moving On) Amongst the residents of Bannerman Road, she was viewed as a quiet and unsociable neighbour. Kelsey Hooper, though likely exaggerating, described her as a "mad woman". (TV: Invasion of the Bane)

A geologist friend gave Sarah Jane a crystal that had been expelled from Krakatoa. Soon, she discovered that the crystal — actually a Xylok — could communicate with her laptop; she followed its plans and built for it a supercomputer in her attic wall, into which the Xylok was integrated. The resulting sentient computer took the name Mr Smith, and provided her with access to countless databases, communications systems, and functioned as a research laboratory. (TV: The Lost Boy, Invasion of the Bane)

Sarah Jane and Bernice Summerfield at some point enjoyed a coffee together and shared memories of their times in the TARDIS. (PROSE: A Mutual Friend)

During Christmas 2006, Sarah witnessed the Sycorax invasion, in which she suspected the Doctor's involvement. (TV: School Reunion)

Reunion with the Tenth Doctor
In 2007, Sarah Jane investigated strange goings-on at Deffry Vale High School. While investigating the school at night she crossed paths with substitute physics instructor "John Smith". Later that night as she investigated the school, she entered a room and was shocked to see the familiar police box shape of the Doctor's TARDIS. Exiting the room, she saw John Smith, who she correctly identified as the Doctor, now in his tenth incarnation. After a very brief catching up, he introduced her to his companion Rose Tyler and Rose's boyfriend, Mickey Smith. In return, Sarah Jane led the Doctor outdoors and reunited him with the inoperative K9 Mark III. The pair reminisced at a coffee shop whilst the Doctor performed such repairs to K9 as he could, managing to restore basic functionality but with only limited power. Meanwhile, Rose felt threatened by Sarah Jane and jealous of the attention the Doctor paid to her. Working together the next day, their mutual animosity and competition got the better of them until Sarah Jane broke the tension by joking with Rose about the Doctor's eccentricities and his quasi-romantic behaviour toward the TARDIS, and they bonded.

Sarah Jane, K9, Rose, Mickey, and the Doctor foiled the Krillitanes' attempts to crack the Skasis Paradigm using their mind-altering oil on the children. In the process, however, the newly reactivated K9 sacrificed his life by blowing up the school with the Krillitanes inside. Sarah Jane came to terms with her inability to move on with her life and left the Doctor's company with resignation. She declined his offer to rejoin the TARDIS, but convinced the Doctor to take on Mickey Smith as a companion — "The TARDIS needs a Smith". The TARDIS dematerialised to reveal K9 Mark IV, a rebuilt version of Mark III with "new omniflexible hyperlink capabilities". Sarah happily departed with the newest iteration of her beloved robot dog. (TV: School Reunion) At some point, she obtained a sonic lipstick. (TV: Invasion of the Bane)

K9's unique abilities, however, forced their separation almost as soon as he arrived. He became involved in a long-term project to stabilise an artificial black hole. A space-time link in a safe in Sarah Jane's attic allowed periodic contact between K9 and his mistress (TV: Invasion of the Bane) and brief teleportation of K9 back to the attic in emergencies. (TV: From Raxacoricofallapatorius With Love, Journey's End, The Lost Boy, The Mad Woman in the Attic)

Sarah Jane found it refreshing to learn about other former companions of the Doctor and their post-companionship lives. In doing so, she learned that Ian Chesterton and Barbara Wright had become professors at the University of Cambridge and had reportedly not aged since the 1960s; Ben Jackson and Polly Wright ran an orphanage in India; Harry Sullivan cured countless people with his vaccines before his death; Tegan Jovanka championed aboriginal rights in her native Australia; and "Dorothy...something", had founded a philanthropy, A Charitable Earth, with which she raised millions of pounds. (TV: Death of the Doctor)

Adventures With Maria, Luke and Clyde
The Bane invasion changed Sarah's life dramatically; previously, she was a slightly cold woman who lived alone, and afterwards, she had a family, both literally, in the case of Luke, and figuratively, in the case of Maria. In 2008, its events exposed her secrets to her young neighbour, Maria Jackson, who had moved into 36 Bannerman Road. With "the archetype", a human boy artificially created by Bane technology, they defeated the Bane Mother. In the aftermath, Sarah Jane adopted the boy, re-naming him Luke, after suggesting Alistair and Harry as names. Sarah was no longer content to live alone and chose to include Maria and Luke in her adventures. (TV: Invasion of the Bane)

She enrolled Luke at Park Vale School, which Maria also attended. At Park Vale, Luke and Maria befriended the "joker" Clyde Langer. However, she soon found something was amiss in the school due the rapid decay of the food there. She soon learned that a branch of the Slitheen had infiltrated the school to use a device they had tricked Luke into partially reworking to drain the sun. However, the device could not handle the power of the sun and exploded, taking some Slitheen with it while others escaped. Because Clyde had aided in the defeat of the Slitheen, Sarah Jane allowed him to join her "gang". (TV: Revenge of the Slitheen)

Accompanied by Clyde and Luke, Sarah Jane next investigated the sighting of a nun at a retirement home. There, she met Bea Nelson-Stanley, who she learned had encounters with Sontarans just like her. She was also hiding a key to a portal that allowed the parasitic Gorgons to invade. Though she was nearly made into its new host, Sarah Jane succeeding in closing the portal and giving the key back to Bea as a memento of her deceased husband. (TV: Eye of the Gorgon)

When teenagers began vanishing during random storms, Sarah Jane found that they were being kidnapped by General Kudlak to fight in the Ghost Wars. However, the trouble was actually caused by the Mistress, a computer that lied to Kudlak about the war's end. After he returned the children he recently had taken back to Earth, Sarah Jane allowed him to leave in peace and search for the other children he had sent away. (TV: Warriors of Kudlak)

When several people in Ealing were stealing gold Sarah Jane started to investigate. She took Maria to the Auriga Clinic where some of the burglars were threated. There Maria was being injected with gold, while Sarah Jane talked to Francis Augur. Sarah Jane later found out that Maria was under the control of the Keratin, who controlled her through the gold injection. The Kreatin used Maria to spy on Sarah Jane. Sarah Jane did not want to worry Maria and did not want to let the Kreatin know, that she was onto them which could endanger Maria's life. Sarah Jane told Clyde and Luke not to mention the Kreatin or Maria's nightly visit of the Auriga Clinic towards Maria. The next night Sarah Jane and Luke followed Maria to the Auriga Clinic. Maria and the other people who were controlled by the Kreatin wanted to take away the oceans of the planet Earth to get the gold of the ocean. The Kreatin wanted to use the gold to be able to control the whole universe. Sarah Jane later pressed a patch with lithium citrate on Maria's neck and Maria got free of the Kreatin's mind control. The Kreatin was killed by salt water and couldn't invade Earth any longer. (AUDIO: The Glittering Storm)

Sarah Jane accompanied Mr. Bradbury history class, which included Maria, Clyde and Luke, on a school trip to the Stone Whisperers. There the alien Ravage started to take control of Luke's mind. Sarah Jane supported Luke when he fought a mental battle against Ravage and helped Luke expelling Ravage from his mind. (AUDIO: The Thirteenth Stone)

Her fate was later switched with Andrea Yates' own by the Trickster, making Earth vulnerable to an incoming meteor. However, when Andrea rejected the Trickster's offer and agreed to die as she had been supposed to, Sarah Jane was able to save Earth from the meteor with Mr Smith's help. Maria's father Alan learned of her secret life and offered his computer tech expertise when they needed assistance. (TV: Whatever Happened to Sarah Jane?)

When a news report showed Luke to be a missing boy belonging to a couple, Sarah Jane was forced to give him up. However, it turned out it was a plot by the Slitheen, who were posing as the humans claiming to be Luke's parents, and Mr Smith, who wished to free his fellow Xyloks from inside the Earth. As the Slitheen were double-crossed by Mr Smith, they helped her and Mr Jackson get to Mr Smith and re-programme him. (TV: The Lost Boy)

When the Daleks transported Earth to the Medusa Cascade in 2009, Sarah Jane and Mr Smith answered the call of former Prime Minister Harriet Jones and, with Torchwood Three, worked to contact the Tenth Doctor by having Mr Smith make every telephone on Earth ring the Doctor's TARDIS. She reluctantly left her son behind in Mr Smith's care and was confronted by two Daleks. (TV: The Stolen Earth) She again met Mickey Smith and made the acquaintance of Jackie Tyler, who saved her from the Daleks, and was then transported to the Dalek base ship, the Crucible. In the heart of the Crucible, she once more met Davros and, working with Jack Harkness, threatened to destroy the Crucible with a warp star she owned. After the defeat of the Daleks, she co-ordinated with K9 and Mr Smith to transmit the vital codes to the TARDIS, whereupon she helped to pilot the TARDIS and tow the Earth back home. As she said another farewell to the Doctor, Sarah Jane commented that, although he often spoke of being lonely, his wide range of companions gave him essentially the largest family on Earth. (TV: Journey's End)

Again with Luke, Clyde, and Maria, she saw off the Sontaran known as Kaagh (the last survivor of the Sontaran invasion of Earth) who wanted to take Sarah Jane back to Sontar to stand trial in the Tenth Doctor's stead. During that adventure, Maria announced that her father had a job offer to move to America and she had decided to let him take it. Six weeks later, she moved out. (TV: The Last Sontaran)

Escapades with Rani, Luke and Clyde
Shortly afterwards, Rani Chandra, an aspiring teenage journalist, and her parents Gita and Haresh moved into Maria's former address and joined Luke and Clyde in defeating a child-stealing energy entity which had inspired the Pied Piper myth. Reluctantly, Sarah took Rani into the team. The entity thrived off of Sarah's fears of clowns which had started one night in childhood. She overcame her fear because of her love for Luke overpowering it when he was kidnapped by the entity. With Clyde's jokes weakening the entity, she forced it back into a piece of the meteor it came from. (TV: The Day of the Clown)

She later went to a show done by Martin Trueman, who correctly guessed her past with the Doctor. This made her curious as to how he knew this. The eventual realisation was that he had been chosen as the host for the Ancient Lights, a consciousness that came from the universe before this one, and wished to control this universe. She tried to save Trueman when the Lights were foiled, but he chooses to be absorbed by them and leave Earth. (TV: Secrets of the Stars)

In 2009 Rani, Clyde and Luke found Janksia's three artefacts, which made Janksia's space ship able to take of. They fell under the influence of the artefact and tried to protect it from non-Persopolisians. Luke hid himself with the black diamond of Earnfield inside a cupboard in the Natural History Museum, where he was doing his work experience. Dr Wendeline Minot called Sarah Jane and asked her for help. Luke brought the diamond to Janksia who fell into a garbage compactor which crushed him to death. Luke was released of the diamond's control. Because the diamond was alien, Sarah Jane Smith told Mr Smith to make a replica of it and gave the duplicate to the museum. She also gave another alien artefact to the museum. In exchange, the staff would not tell anyone that Luke had taken the black diamond. (AUDIO: The Time Capsule)

In the same year the Victorian house of the Burden family swapped places with the O'Brain's house from 2009. Sarah Jane helped to place the houses into correct time again. (AUDIO: The Ghost House)

She later went to search for an alien in hospital, leaving Mr Smith shut down and notes for her companions not to touch alien artefacts in her attic. It was during this time Rani found the Berserker pendant and left it there, only for Clyde's dad to take it and nearly turn into a berserker from using the pendant to get whatever he wanted. Sarah Jane returned just in time as Clyde had been forced to forget Luke, Rani and his own mother. They returned Paul to normal and got rid of the pendant. (TV: The Mark of the Berserker)

Returning a boy to his home time through a time fissure, Sarah Jane found the other side led to Foxgrove in 1951, the time of her infancy. She wished to meet her parents and did so, but disabled their car to prevent them from dying. However, once the Trickster appeared and revealed it had all been a part of his plan to manifest corporeally, Sarah Jane repaired the car and sent her parents off, now feeling immensely proud of them. (TV: The Temptation of Sarah Jane Smith)

Later, Mrs Wormwood returned to Earth alongside the Sontaran Kaagh in an attempt to summon Horath, the immortal tyrant of the Dark Empire. With help from Brigadier Lethbridge-Stewart and due to infighting between Kaagh and Mrs Wormwood, they were able to stop this apocalypse and trap the duo between dimensions. This was the last time Sarah Jane saw the Brigadier in person for a while. (TV: Enemy of the Bane)

Sarah Jane and her friends fought Androvax, a Veil who possessed her body to gain access to nanobots to build a spaceship to leave Earth. However, thanks to Luke, Rani, and Clyde, as well as a Judoon, she got it back and learned the Judoon had "grounded" Rani and Clyde to Earth for impeding his search. (TV: Prisoner of the Judoon)

She and the gang also helped a lonely alien named Eve get back to her Ship and fly away with her friends. Ship absorbed the energy from the black hole K9 was guarding to take off, bringing him back to Sarah Jane's side. She was also temporarily removed from existence by Ship, who was damaged and did not bother to correct its mistake, until Adam, Eve's son, reversed the damage in the future. (TV: The Mad Woman in the Attic)

When Rani, Clyde and Luke missed the schoolbus which would take them on a classtrip to Snowdonia Sarah Jane brought them there. As she couldn't return that day she planed to stay one night. In Snowdonia she suddenly saw Rani at two places at the same time. Sarah Jane later found out that the second Rani was one of the Shadow People, an alien species who were created by the Shedagen to imitate and serve other creatures. The shadowy figure could only exist among other creatures. It was scared, that if Sarah Jane and her friends leave it would stop existing. So it didn't want to let them go. Sarah Jane convinced the figure to let them drive away. Sarah Jane waved goodbye to the figure before they left. (AUDIO: The Shadow People)

Sarah Jane later met Peter Dalton and they got engaged, much to Luke, Rani, and Clyde's surprise. At her wedding she had two very special, uninvited guests, her greatest ally and arch enemy. She was teleported to limbo by the Trickster and separated from her companions and the Doctor. She had to allow Peter to sacrifice himself to defeat the Trickster. She had genuinely been in love with Peter and when she and the others returned to Earth, she was left heartbroken. She was checked up on by Luke, Clyde, and Rani as well as the Doctor, who allowed Sarah Jane's gang to have a look inside the TARDIS. She then bid another farewell to the Doctor in the manner of their original departure, both asking each other not to forget them. (TV: The Wedding of Sarah Jane Smith, The Hand of Fear)

Invited by Celeste Rivers to partake in a search for the ghosts of those taken by the spirit Erasmus Darkening, Sarah Jane found that he was not a ghost, but an alien who had become trapped between dimensions due to Lord Marchwood damaging the machine he was using to try to get home. Sarah Jane destroyed him and the machine, allowing those trapped by Darkening to finally pass on. (TV: The Eternity Trap)

The Mona Lisa came to life shortly after Sarah Jane and Luke argued for the first time about typical teenage habits. Sarah Jane was temporarily trapped in a painting by the Mona Lisa, but was freed after her companions tricked the painting and destroyed her "brother". (TV: Mona Lisa's Revenge)

Later Sarah Jane attempted to thwart another Slitheen plot which threatened the Earth. Despite the best efforts of Luke, Rani, Clyde, K9, and her, the Slitheen could not be stopped. However, members of the Blathereen family arrived in time to stop the Slitheen. They tricked Sarah Jane into accepting a gift: a Rakweed plant. It mutated overnight and began to spread across London, threatening to kill anyone infected by its spores. Luke was the first to inhale the spores and almost died. A way for Mr Smith to destroy the Rakweed was discovered, but Sarah Jane was forced to kill the Blathereen, an act she immediately regretted. (TV: The Gift)

When other members of the Slitheen-Blathereen family kidnaped Sarah Jane Rani was forced to help to grow Rakweed, so that Sarah Jane was released. (GAME: Plants) The Rakweed was later destroyed by Clyde. (GAME: Sound)

Sarah Jane and Luke were informed by Mr Smith that a space ship crashed on Earth. They went to crash site of the ship, saved the pilot of the ship and brought him to the attic. Soon after this the Krulius appeared and teleported himself, Sarah Jane and the pilot to his space station. Sarah Jane used her sonic lipstic to inform Mr Smith about her whereabouts. Mr Smith told the Judoon where the Krulius was hiding. The Judoon arrested the Krulius and brought Sarah Jane back to Earth. (COMIC: Monster Hunt) After this, Rani was teleported to the Krulius space ship. She escaped and returned to the attic and told Sarah Jane, Luke and Clyde about her experiences. Sarah Jane said that they have to expect trouble since the Krulius had returned. (COMIC: Return of the Krulius) Meanwhile the Krulius prepared for a war against Sarah Jane Smith and her gang. He came with an army of aliens to Bannerman Road and attacked Sarah Jane's house. Sarah Jane and her gang fought the Krulius and his army off. The army had to return to the space ship. (COMIC: Defending Bannerman Road)

When a story about Hank Carter and the Wraith Warriors was written, a journal with Sionic Paper and these figures began to appear in the real world. Sarah Jane helped Rani Chandra and Gregory P. Wilkinson to defeat Hank Carter and the Wraith Warriors. (AUDIO: Wraith World) Later the Umorgus tried to invade Earth and were stopped by Sarah Jane and Luke. (AUDIO: Deadly Download).

Luke told Sarah Jane that he would be doing his A levels a year early whilst she was held captive by a Slitheen. Rani and Clyde quickly defeated the Slitheen with a bucket of vinegar and Sarah Jane said Luke should go to university. (TV: The Nightmare Man)

After the incident with the Master Race, Sarah Jane asked Mr Smith to create a cover story so that no one would suspect more alien activity, using a fake story of the wi-fi system suffering a major technical malfunction all around the world that caused everyone to have hallucinations. She was later told by Luke that the Doctor had arrived and saved his life. She watched as he waved goodbye before entering the TARDIS; having witnessed the upcoming events for the Doctor before, she smiled tearily, knowing that this would be the last time she would see the Doctor, at least in that incarnation. (TV: The End of Time)

After Luke
When the time came, Luke passed his A Levels with flying colours, as Sarah Jane expected. Luke was then plagued by nightmares caused by the extradimensional Nightmare Man entity. (TV: The Nightmare Man) During that time Sarah Jane and Martha Smith-Jones were occasionally meeting up for a coffee. They had become friends and Sarah Jane had told Martha all about Luke. When Luke suffered from the nightmares and did not feel well, she wanted to call Martha. Sarah Jane thought that, as a doctor, Martha might be able to help. However, Luke told Sarah Jane that he was all right and Sarah Jane didn't make the call. (PROSE: The Nightmare Man) Despite not being able to help, Sarah Jane was amazed that Luke, Clyde, and Rani entered the same nightmare to be together and defeat him by overcoming their fears, trapping the Nightmare Man in Clyde's nightmare of an older version of herself bragging about Luke. Alive and well, Luke left for the University of Oxford in Sarah Jane's old car, a yellow Volkswagen Beetle, that she had given him after the repairs had been finished. She sent K9 with Luke to care for him. (TV: The Nightmare Man)

Although Luke and K9 were no longer with Sarah Jane, Clyde and Rani stayed behind and the trio continued to have adventures in 2010. Androvax returned to Sarah Jane and asked for her help. Along with the Men in Black, they saved Earth from hyperdimensional cataclysm, allowing Androvax to leave Earth without destroying it and find a new home planet for the remnants of the Veil species. (TV: The Vault of Secrets)

In the same year an old Nadloon circus comedy cruiser crashed in the Thames. Sarah Jane Smith and her friends recovered the cruiser from the Thames. (WC: Defending Bannerman Road)

Sarah Jane, Rani and Clyde went to the Pharos Institute again to study a fossilised Silurian egg. (TV: SJAF 6)

She received word from UNIT that the Doctor had died and that they were taking charge of his funeral with the Shansheeth. However, Sarah Jane was sceptical about this as she believed that she would feel something if the Doctor died. She also met her immediate predecessor as the Doctor's companion, Jo Jones, and bonded over memories of their travels with the Doctor; Jo was just as sceptical. When it was revealed the Shansheeth had lied about the Doctor's death, Sarah was shocked to come face to face with the Doctor in his newest body. She and Jo were soon captured by the Shansheeth so their memories could be used to create a new TARDIS key via a memory weave. With the help of the Doctor, the two women overloaded the machine and hid in a lead-lined coffin as it self-destructed. After this, she used "TARDIS" as a search word and learned about other ex-companions working to help make Earth a better place. "With friends like us, he's never going to die, is he?" (TV: Death of the Doctor)

Sarah Jane was teleported to a sub-dimension along with the rest of humanity by the Automatons. Clyde and Rani remained on Earth due to their grounding by the Judoon and they solved the mystery, returning alien king Gavin back home after he ordered the return of the human race. Sarah Jane told Clyde and Rani how proud she was of them and after having Mr Smith fix the records that Gavin moved to Australia, got pizza for her young friends to celebrate their first successful adventure without her. (TV: The Empty Planet)

Soon after, the Bannerman Road gang investigated a shop owned by a mysterious shopkeeper who transported Sarah Jane, Clyde, and Rani to three different moments in time to obtain pieces of chronosteel using a time window. Arriving in 1889, Sarah Jane met a young woman named Emily Morris who was investigating a haunted house. They discovered the house was melding with its future self and saw two children locked in a room on fire. This was how Emily had lost her mother nine weeks earlier. Under Sarah Jane's guidance, Emily used her fear to travel through time and open the door, saving the children and obtaining the chronosteel key. Sarah Jane took the key and began to teleport back to 2010, but Emily wanted Sarah Jane to stay with her and took the key, inadvertently sending Sarah Jane back to the future empty handed. However, Emily passed the key down to her granddaughter, Angela Price, who gave it to the Shopkeeper. He stabilised the time window and teleported away, saying his parrot's work was done. Sarah Jane then had a cup of tea and chat with Angela to learn more about Emily and Angela. (TV: Lost in Time)

Sarah Jane and the gang met Ruby White, a woman who supposedly defended the Earth like Sarah Jane. Sarah Jane thought she was getting too old to continue defending the planet and passed her duties on to Ruby. It turned out Ruby was a Qetesh, a member of a race that drained life force through emotion and excitement, and she had been draining Sarah Jane whenever they met. Ruby handcuffed Sarah Jane next to her stomach — a separate part of her being — and left her in a cellar to drain her life force directly. She was eventually set free by Clyde, Rani, and Luke who had come back from university to defeat Ruby, using her artificial intelligence to show every human on the planet a hologram of a meteor headed towards them, causing Ruby to absorb over 6 billion thrills. Ruby's stomach was destroyed and all of the life force she had stolen from Sarah Jane returned. Sarah Jane then used Ruby's teleport bracelet to warp the Qetesh back to her prison ship where she belonged. (TV: Goodbye, Sarah Jane Smith)

Adopting Sky and subsequent adventures
In 2011, a baby was left on Sarah Jane's doorstep. She named the young girl Sky. The baby caused power fluctuations around Bannerman Road. Sarah Jane and Rani investigated a crash site for a supposed meteor the previous night, where she met Professor Rivers again. When they found that Clyde and Sky had been taken to a power plant by Sky's mother, Miss Myers, she saw Sky's transformation from baby to a pre-teen. Rani and Clyde deactivated the core of the power station, foiling Miss Myers' plot to bring the entire Metalkind species to Earth that would have caused Sky to detonate and destroy them all, as per her purpose. When Miss Myers and the Metalkind had left Earth at supposedly the cost of Sky's electrical powers, the gang returned to Bannerman Road where Sarah Jane decided to adopt her after learning that it was the Shopkeeper and Captain who left the child with her as the Shopkeeper explained in person. (TV: Sky)

Sarah Jane enrolled Sky in Park Vale Comprehensive School the day it rained fish. Sarah Jane, along with the other people important in Clyde's life, was put under Hetocumtek's curse making her turn against Clyde and tell him he was to stay away from her. The curse on her was later broken with the help of Sky, who urged her and Rani to remember what Clyde meant to them. She and the rest of the gang reunited with Clyde and together defeated Hetocumtek, lifting the curse. Sarah Jane helped Clyde look for his new friend but they later learned that she had already left London on a haulage truck. (TV: The Curse of Clyde Langer)

As she was one of the top three journalists in the United Kingdom, Sarah Jane was invited to the rehearsal of the launch of the SerfBoard by Joseph Serf. However, she found that Serf's assistant, John Harrison, was actually the one pulling the strings and Serf himself was a hologram controlled by enslaved Skullions. With the help of her two children and one of the former cleaning staff, Adriana, Sarah Jane managed to sink John's plans by using the hologram's hypnotism on the audience to convince them that the computer was rubbish. After John was teleported away with the escaping Skullions, Sarah Jane recommended Adriana join UNIT as her kind-heartedness towards friendly aliens was just what they needed; she said mentioning her name would ensure good pay. (TV: The Man Who Never Was)

Sarah Jane, Clyde, Rani and Sky went to an antiques auction where Sarah Jane found the head of the Difference Golem Adam. Adam was brought back to life. He escaped and tried to activate other Difference Golems. Sarah Jane helped to find Adam and Adam's consciousness was then brought back to the future. (AUDIO: Children of Steel)

An alien ship landed at White Cross shopping mall. Sarah Jane, Clyde, Rani and Sky went there to find out why the ship has landed there. They later found out that the Veritas were hunting the magician Zandoo, because they thought practising magic was like lying. Before the Veritas could find Zandoo, they realised that Sarah Jane had lied a lot to keep the existence of aliens hidden infront of humans. They caught Sarah Jane and showed her former lies. Then they wanted to punish Sarah Jane for her lies. When the Veritas saw the chaos that was caused, as the humans in the shopping centre got to know about aliens they realised that Sarah Jane only lied to protect the humans. Sarah Jane convinced the aliens that Zandoo also wasn't lying and that his magic show was only a kind of entertainment. (AUDIO: Judgement Day)

Later Life
Sarah Jane and her gang continued to have adventures, defend Earth, and save countless lives. Statues were raised in their honour and they left behind a legacy that lasted forever. (PROSE: The Wedding of Sarah Jane Smith, TV: The Man Who Never Was) Sarah Jane was still alive in 2013 according to the Eleventh Doctor. (COMIC: The Girl Who Loved Doctor Who )

At some point between 2011 and 2059, occupation of Sarah Jane's house at 13 Bannerman Road, Ealing, passed to Rani Chandra and her family. (TV: The Mad Woman in the Attic)

According to one account, Sarah Jane eventually had a daughter named Lauren and a grandchild called Lily. The Fifth Doctor visited her one Christmas and helped Sarah Jane bond with her granddaughter. (PROSE: Lily)

Andrea Yates' world
The Trickster swapped Sarah Jane's destiny with that of school friend Andrea Yates. Consequently, Sarah Jane, not Andrea, drowned in 1964 on a school trip to a pier and never led the life she would have alongside the Doctor. Had her life not been restored, life on Earth would have been likely destroyed by an asteroid that only Mr Smith could have stopped. (TV: Whatever Happened to Sarah Jane?)

Donna's world
In Donna's World, time was altered as the Doctor's companion Donna Noble was assaulted by a member of the Trickster's Brigade who coerced her into turning right instead of left six months prior to Donna's first encounter with the Tenth Doctor, thereby preventing their meeting and her from saving his life.

In 2008, Sarah Jane investigated the Royal Hope Hospital with Maria, Clyde and Luke. (TV: Turn Left) When the Royal Hope Hospital was teleported to the moon by the Judoon, (TV: Smith and Jones) Sarah Jane tried to step into the Doctor's role and defuse the situation. Though she did manage to deactivate the MRI weapon, she could do nothing about the hospital's dwindling supply of oxygen; along with everyone else, she, Luke, Maria, Clyde, and Martha Jones all suffocated. (TV: Turn Left)

The Trickster's Earth
The Trickster used an elaborate plan to entice Sarah Jane into preventing the death of her parents. This gave him the chance to manifest himself fully in our reality and take control of the planet in yet another alternate timeline. Sarah Jane's actions made her a notorious figure in this dystopian world. In the end, Sarah Jane's parents chose to sacrifice themselves in order to circumvent the Trickster's plan, erasing the alternate timeline. (TV: The Temptation of Sarah Jane Smith)

Parallel universe Earth
The Eleventh Doctor once visited a parallel universe version of Earth in which his adventures were chronicled in a television series titled Doctor Who. In this universe, Sarah Jane was portrayed by an actress named Elisabeth Sladen, who was deceased by this time, though the Doctor stated that Sarah Jane in his universe was still alive and well and living in Ealing. (COMIC: The Girl Who Loved Doctor Who)

Personality
As a companion, Sarah Jane was confident, courageous, compassionate and inquisitive. She had a sharp mind and tongue. She was also something of a feminist; she was infuriated when the Third Doctor asked her to make coffee (TV: The Time Warrior) and she often sparred verbally with fellow companion Harry Sullivan over his old-fashioned and unintentionally patronising attitude towards her. Her feminism was more practical than fanatical and did not get in the way of close friendships with Harry and the Doctor himself. She once said that she loved Harry very dearly. (TV: Death of the Doctor)

Sarah Jane shared a strong rapport with the Doctor. Her later life was shaped by her finding him a tough act to follow. She stopped short of saying she had fallen in love with him, though several of her exchanges with him after their reunion and the context of one of her conversations with Rose strongly implied she had developed deep feelings for him. (TV: School Reunion) However, her relationship with the Doctor was said to be more than a romance. (TV: Secrets of the Stars) Despite the passage of time, she maintained her can-do personality. After reuniting with the Doctor, she remained a close friend of his.

During her time defending Earth with her young friends, Sarah Jane was a motherly and excellent leader. She was very protective of her young allies and blamed herself when they got into trouble. (TV: Goodbye, Sarah Jane Smith et al) This made her rather cold and secretive to strangers but her gang helped her open up to others. (TV: Invasion of the Bane, The Mad Woman in the Attic) She adored her young friends, considering them her family. (TV: The Lost Boy et al) She was essentially to them what the Doctor was to her: an older, wiser mentor.

Sarah Jane was extremely proud of Luke and loved him, calling him the most important thing in the universe. (TV: The Gift et al) When she met Jo Jones, they became very fond of each other. They hugged and even high-fived. (TV: Death of the Doctor) She didn't think babies cute but rather rubbery. (TV: Sky) She considered the lives of homeless people to be the most alien of all and was saddened that many people did not know because they did not want to. (TV: The Curse of Clyde Langer)

Sarah Jane also loved K9 deeply, due to him being the nearest thing to a family she had for over 20 years, and was devastated at the prospects of losing him. (TV: School Reunion, The Nightmare Man) She also showed great compassion for Mr Smith, often treating him like a human rather than a computer. (TV: The Wedding of Sarah Jane Smith, Mona Lisa's Revenge)

In contrast to her periodic and proficient use of firearms in her twenties, Sarah Jane grew fiercely opposed to violence and killing, and showed sympathy to her enemies like Martin Truman, the Slitheen-Blathereen and even Androvax, (TV: Secrets of the Stars, The Gift, The Vault of Secrets) as they simply did these things, not because they were bad, but because they were hurt or felt inferior. This went hand in hand with her strong mind. However, this pacifistic nature caused her enemies to frequently consider her naive, most notably Miss Myers and John Harrison. (TV: Sky, The Man Who Never Was) She grew to dislike the military, including UNIT and Torchwood, but remained a friend of the Brigadier and felt that her gang could not defeat a Sontaran or the Dark Hoard but knew UNIT could. (TV: The Last Sontaran, Enemy of the Bane, Goodbye, Sarah Jane Smith) She hated the Trickster, considering him to be the most malevolent enemy she had as he had tried using her friends and family against her to try manifesting. (TV: Sarah Jane's Alien Files episode 1)

Rani once pointed out to the Tenth Doctor that Sarah Jane didn't like being called just "Sarah", though he replied, "She does by me". (TV: The Wedding of Sarah Jane Smith) Indeed, during her years travelling in the TARDIS, the Doctor, along with a few other individuals such as Harry and Mike Yates, referred to her many times simply as "Sarah".

Skills
Despite her later dislike of violence, Sarah was an excellent shot with firearms (TV: Pyramids of Mars) and knew Venusian karate. (TV: A Girl's Best Friend)

She was resistant to hypnosis, even if it was more powerful alien technology rather than simple methods, (TV: The Man Who Never Was) due to having already been put through it several times in her youth while journeying with the Doctor. (TV: Planet of the Spiders, The Masque of Mandragora, The Hand of Fear) Sarah could also whistle. (TV: Revenge of the Cybermen)

Sarah Jane was one of Britain's top journalists. Just three of the country's very top journalists have been invited to watch the presentation of the SerfBoard. Sarah Jane was one of them. (TV: The Man Who Never Was) She also wrote her own book UNIT Fighting for Humankind. (TV: Whatever Happened to Sarah Jane?)

Popularity and significance
Sarah Jane Smith is one of the most popular of the Doctor's companions, as well as one of the most iconic. Apart from Brigadier Lethbridge-Stewart, no other individual has maintained a higher profile as a Doctor Who companion. On-screen, she has appeared with the Third, Fourth, Tenth and Eleventh Doctors, as well as with First, Second, and Fifth Doctors in The Five Doctors. Accordingly, she and Brigadier Lethbridge-Stewart are the only companions to have each appeared on-screen alongside at least seven incarnations of the Doctor. The two characters' actors, Elisabeth Sladen and Nicholas Courtney, coincidentally died within weeks of each other in 2011; she was honoured with an "In memory of" dedication at the start of the 2011 series première The Impossible Astronaut, followed by a half-hour retrospective TV special airing immediately after that episode, while Courtney was eulogised on-screen (using Lethbridge-Stewart as his in-universe proxy) in the 2011 series finale The Wedding of River Song; and each was memorialised with retrospective pages on the BBC's Doctor Who website.

On-screen, Sarah has met the Daleks, the Cybermen, the Ice Warriors, the Slitheen, the Judoon, the Master (in The Five Doctors) and Davros. She is the only companion to have met Davros in two different stories: his début serial Genesis of the Daleks and the 2008 episode Journey's End, more than 33 years later. Her début story, The Time Warrior, introduced the Sontarans. She, K9 and Brigadier Lethbridge-Stewart are the only classic era companions to have appeared on Doctor Who in the revived era, aside from archival footage, and she did so in four episodes. Her iconic farewell scenes with the Fourth Doctor in The Hand of Fear were reenacted with the Tenth Doctor in The Wedding of Sarah Jane Smith and School Reunion.

She and K9 were together the first companions to have been given their own spin-off series, and were the only ones have been spun-off in the "classic era".

Casting
Elisabeth Sladen was not the original actress cast to play Sarah Jane. The role originally went to April Walker. She was fully contracted for the whole of season 11, but Barry Letts discovered that she had no real chemistry with Jon Pertwee. She was quietly paid off for her entire contract and Elisabeth Sladen was brought in to replace her. (INFO: Invasion of the Dinosaurs) Though it was known for years that there had been "another Sarah Jane", Letts and Sladen went to their graves without revealing her identity. Walker's name was discovered only when the DVD info text writer chanced across her name while doing research into Dinosaurs.

Sarah Jane spin-offs
Sarah Jane has appeared in two television spin-offs, K9 and Company, introducing and co-starring K9 Mark III, (which never got beyond the pilot episode, A Girl's Best Friend), and The Sarah Jane Adventures. Starting in 2002, she appeared in two seasons of an audio series, Sarah Jane Smith. The K9 Annual gives some idea of how the K9 and Company series might have progressed if it had gone to a full series.

Her spin-off, The Sarah Jane Adventures, hosted the Tenth and Eleventh Doctors, along with classic era companions Brigadier Lethbridge-Stewart, Jo Grant, K9 and herself. No Doctor nor classic era companion has appeared on any other spin-off (although the Doctor's TARDIS, containing the Tenth Doctor, is heard arriving off-camera at the end of the Torchwood episode, End of Days which dovetails directly into the start of Utopia). The first use of classic era archival footage in the revived era occurred in the opening pan of her series' pilot, Invasion of the Bane, and the first reference to the UNIT dating controversy occurred in The Lost Boy, before either aired on Doctor Who.

The Sarah Jane Adventures was to have featured additional classic era stars, until cancelled by the death of Elisabeth Sladen. Russell T Davies revealed in issue 445 of Doctor Who Magazine, as confirmed by Sophie Aldred in an interview, that Aldred was to have returned as Ace, both in present day and flashback sequences which potentially might also have included Sylvester McCoy as the Seventh Doctor.

Sarah Jane special
The Doctor Who Magazine special for Holiday 1992 concentrated on Sarah Jane Smith. The article The Roving Reporter details her life from an in-universe perspective, establishing several of the "facts" later corroborated by The Sarah Jane Adventures, except that it uses the "near future" version of UNIT dating.

Continuity and canon
Sarah Jane Smith's return to television in School Reunion overwrites some previously established continuity from spin-off merchandise, such as novels. Apart from The Five Doctors, which shows Sarah meeting up with the Doctor (in the form of his third incarnation), in the Doctor Who Magazine comic Train-Flight, she shared an adventure with the Seventh Doctor. Interference - Book One and Interference - Book Two portray her meeting with the Eighth Doctor and inviting Samantha Jones to stay with her. Terrance Dicks' short story Farewells also shows a reconciliation with the Fourth Doctor. School Reunion strongly implies that the Doctor and Sarah never met again after their parting in The Hand of Fear.

Lawrence Miles' Christmas on a Rational Planet refers to Sarah under the name "Sarah Jane Morley" in 1998. The same author's Interference — Books One and Two, set partly in 1997, has the 1997 version of Sarah seeing her future self marrying a man named Paul Morley a few years in her future. This is contradicted by The Wedding of Sarah Jane Smith, in which Sarah has explicitly never been married before her wedding to Peter Dalton.

The short story Lily by Jackie Marshall shows the Fifth Doctor meeting with an older Sarah, who has a grand-daughter.

The Sarah Jane Adventures uses background from the The Roving Reporter article, with the change of pushing her birthdate back a few years to fit in better with the idea that the UNIT stories took place in approximately the years of broadcast.

The Big Finish Productions audio drama series Sarah Jane Smith released its final episode only a few weeks before School Reunion was broadcast. Its continuity is not necessarily overridden by the new series, and in fact the absence of K9 from the audio stories is explained in School Reunion, which also establishes that Sarah Jane is still an active investigator, as profiled by Big Finish.

Spelling
Though rendered "Sarah Jane" in closing credits on television and in the bodies of most text-based narratives, Smith's forenames were consistently hyphenated by the letterers of Polystyle Publications, Ltd. Every TV Comic story held that she was "Sarah-Jane".

Taken from the reference book, Companions: Fifty Years of Doctor Who Assistants (written by Andy Frankham-Allen and published by Candy Jar Books in June 2013)...

"It is important to note from the outset that, certainly according to her, her first name is ‘Sarah’ and not ‘Sarah Jane’. The only time she is seen to use ‘Jane’ is when introducing herself as ‘Sarah Jane Smith’. However, her family seem to call her ‘Sarah Jane’, including her Aunt Lavinia. (TV: A Girl's Best Friend) and her parents. (TV: The Temptation of Sarah Jane Smith) The Doctor, occasionally, refers to her as ‘Sarah Jane’, a term of affection from him (used, most notably, moments before he ‘dies’ in his lab). Once her time with the Doctor comes to an end, Sarah takes to calling herself ‘Sarah Jane’ again, and doesn’t allow anyone, except the Doctor, to call her ‘Sarah’.
