School Reunion (TV story)

School Reunion was the third adventure of Series 2 of Doctor Who. This episode marks the return of Sarah Jane Smith and K9 Mark III.

Synopsis
Sarah Jane Smith and K9 join the Tenth Doctor, Rose and Mickey to investigate sinister events at a modern-day comprehensive school, and take on the evil Krillitanes.

Plot
At the Deffry Vale High School, the headmaster, Mr Finch, notices a student waiting outside his office. She says she has a headache, and has not simply gone home because she lives in an orphanage. Mr Finch offers sympathies that there is no-one to miss her, and invites her into his office; it is nearly time for lunch. The door closes, there is a flap of wings, and the girl screams.

Together with Rose, the Doctor, under the alias "John Smith", has gone undercover in the school. He teaches a physics class, asking a few simple questions about physics, which none can answer except a student called Milo. After asking a few more questions, the Doctor advances onwards through higher levels of knowledge, finally asking how to travel faster than the speed of light. Milo answers every question without missing a beat.

Meanwhile, Rose is working undercover in the cafeteria. At lunch, she goes over and talks to the Doctor, complaining about the last two days. The Doctor mentions that it was Mickey who alerted them to something odd going on, and he was right. Everyone at the school seems too well-behaved, and there is something odd about the chips. Rose eats a few, saying she likes them. The school menu has been designed by Mr Finch himself to improve concentration and performance. Another teacher, Mr Wagner, approaches one of the students, Melissa. He tells her that Milo has failed him, so she is being moved up to the top class. He also summons another student, Luke, but not Kenny, who for some reason is not allowed to eat the chips. The Doctor observes all this quietly, then looks up and sees Mr Finch gazing down on the cafeteria floor, watching everything.

In the kitchen, Rose watches the other kitchen staff, all wearing gloves and face in masks, bringing in a large barrel. Mrs Jackson, the head Dinner Lady, warns them not to spill a drop. Mickey calls Rose on her mobile phone, telling her about the massive UFO activity he has discovered around the area. However, his investigations are being blocked by something called Torchwood. Rose, in turn, tells him that the kitchen staff were all replaced three months ago with a new set. As they speak, the barrel slips, spilling something over one of the staff who starts to burn. The rest usher her into a side room. As Rose starts to phone for an ambulance, Mrs Jackson tells her not to worry — the woman is all right, even as Rose hears screams and sees lots of smoke appear. Rose glances down at the barrel, which is leaking a golden, oily substance.

In the Maths classroom, Mr Wagner tells the children at their computers to put their headphones on. The screens flicker on, and the monitors begin to display a green rotating cube with rapidly scrolling, alien-looking symbols, and seemingly random text on the right. The children start to type on their keyboards with incredible speed.

Mr Finch escorts a journalist, Sarah Jane Smith, around the school. Sarah has been assigned to a profile on him, and Finch explains that one of the policy changes he has made are free — but compulsory — school dinners. In the staff room, the Doctor is speaking to Mr Parsons, head of History, who tells him of the extraordinary knowledge of his students since Finch became Headmaster. Also, since his arrival, seven teachers came down with flu, and were replaced by strange new ones. The teacher the Doctor is replacing resigned when she won the lottery, which she did not even enter. Mr Finch brings Sarah into the staff room, and when the Doctor sees her, he begins to smile. When he introduces himself as John Smith, Sarah remarks that she once knew a man who went by that name. When she finds out that "Smith" is a new teacher, she starts asking him if he has noticed anything odd. Her questions show that she has lost none of her inquisitive nature, and the Doctor is delighted, although he does not reveal his real identity to her.

As the Doctor wanders the halls in a slight nostalgic haze, Kenny goes into the Maths room. He sees, to his shock, a bat-like creature beneath one of the desks, which transforms rapidly into Mr Wagner. Wagner tells Kenny to leave, and the boy beats a hasty retreat. School ends for the day, and night falls. Sarah Jane Smith breaks into the school to explore, even as the Doctor, Rose and Mickey do the same. The Doctor sends Mickey to the Maths room and Rose to get a sample of the oil while he checks out the headmaster's office. All through this there are the sounds of flapping, the occasional shriek and winged shadows flitting across walls.

Sarah Jane Smith, trying to break into Mr Finch's office, notices she is being watched. She enters a store room and to her shock sees the TARDIS standing there. Backing out, she sees "John Smith", who calls her "Sarah Jane", and she realises it really is the Doctor. After a brief exchange, they hear a piercing scream and they run towards the sound, meeting Rose along the way. The Doctor introduces the two women, and Rose is immediately jealous. The scream turns out to be Mickey, who opened a cupboard only to be covered in shrink wrapped rats. Sarah surmises that the rats are for dissection, but Rose retorts that rat dissection hasn't been used in schools for years, making a snide dig at Sarah's age. As they head for Finch's office, Mickey welcomes the Doctor to "the missus and the ex" — every man's worst nightmare. The Doctor suggests that the rats may be food for something, and when the enter Finch's office, they find out what it is: thirteen large, bat-like creatures hanging from the ceiling, asleep. They back out hurriedly, but as they shut the door, one of the creatures wakes up and shrieks. Outside, the Doctor tells them they have to go back in so that he can use the TARDIS to analyse the oil sample Rose procured. Sarah tells the Doctor that she may have something that can help him, and takes him to her car, revealing an inactive and rusty K9 MK III, with one of his side panels missing. Sarah explains that one day it had just stopped working, and she could not repair the advanced technology inside it.

Not knowing that they are being trailed by Mr Finch and another bat-creature, they go in Sarah's car to a nearby café, where the Doctor works on repairing K9. Mickey teases Rose about her jealousy, while Sarah asks the Doctor why he never came back for her. The Doctor tries to brush it off, saying that she was getting on with her life. Sarah replies that he was her life. The hardest thing was adjusting back to mundane life after all she had seen. She asks him why he could not have come back, and the Doctor turns serious and does not reply.

K9 comes back to life, and recognises the Doctor as its master. He smears some of the oil sample on its eye sensor, and K9 determines it is Krillitane oil. The creatures are Krillitanes, a composite species which take the best physical parts of other species they conquer. The Doctor did not recognise them because they looked different back then. He realises that they are doing something to the children.

As they leave the café, Rose asks the Doctor if Sarah is her future; that she will be left behind like all his other companions. The Doctor tells her he did not go back for Sarah because it would have been too hard; "I don't age. I regenerate. But humans decay, you wither and you die. You can spend the rest of your life with me. But I can't spend the rest of mine with you. I have to live on, alone. Thats the curse of the Time Lords" (-The Doctor) Mr Finch hears the phrase "Time Lords" and sends the other Krillitane down to swoop over them, although it does not harm anyone.

The next day all of them return to the school. The Doctor sends Rose and Sarah to discover what is inside the computers, and tells Mickey to stay in the car with K9 as surveillance — a task Mickey compares to being "sent to the back of the class with the safety scissors and glitter". The Doctor himself is going to have a word with Mr Finch. The two confront each other at the swimming pool. Finch confirms that he is a Krillitane named Brother Lassar; the wings being a recent addition to their form, having been obtained from the invasion of Bessan ten generations ago. What the Doctor sees as Human is just a morphic illusion. Surprised to see a Time Lord, Finch refers to them as a race of pompous, dusty senators, afraid of change and chaos, and now all but extinct. He can sense, however, that the Doctor is different, but still refuses to reveal his plans, challenging the Doctor to work it out. Finch says that they are not enemies, and asks if the Doctor would declare war on them. The Doctor quietly replies that he had much more mercy when he was younger, and this is their only warning. Finch promises, however, that the next time they meet; the Doctor will join with him.

Working on the computers, Sarah and Rose begin to argue about who has had more experience time travelling, yelling the names of the different monsters they have met. Both of them soon realise the argument is pointless and bond by comparing notes on the Doctor, bursting into laughter when he enters, much to his consternation.

Mr Finch tells the other Krillitanes that they are moving to the final phase. The school will be sealed, and they will become gods. Even though it is break time, intercom calls all pupils to class and the staff to the staff room. All the pupils appear strangely happy that the break has ended early, except Kenny, who hesitates, but eventually follows the others inside. Meanwhile, the Krillitanes begin by devouring the rest of the staff.

In the Maths room, the Doctor finds the computers fixed with a deadlock seal, something which even the sonic screwdriver cannot breach. Mr Finch seals all of the school's exits while Mr Wagner activates the computer programme which the children begin working again. Kenny finds himself unable to get out of the school, but attracts Mickey's attention. Mickey reactivates K9, asking it if it has some way to get in the school, but K9 reminds Mickey that he is in a car. Meanwhile, Rose, Sarah and the Doctor watch the symbols flash on a large screen, and the Doctor works out what it is. The Krillitanes are trying to solve the Skasis Paradigm. The Doctor explains that the Paradigm is the God-Maker, the Universal Theory; whoever solves it will be able to control the building blocks of the universe — all of time and space. The Krillitanes are boosting the children's intelligence with the oil, using them and their imaginations as a giant processing device. Finch appears at this point, asking the Doctor to join them, tempting the Doctor with the ability to change the universe, to save everyone, even restore the Time Lords. He also offers Sarah and Rose the chance to travel with the Doctor forever, never growing old. For a moment the Doctor does appear tempted, but Sarah tells him that pain and loss define them as much as happiness or love. Everything has its time, and everything ends, whether a world or a relationship. The Doctor picks up a chair and hurls it at the screen, smashing it. He tells Rose and Sarah to get out.

Mickey crashes the car through the front doors of the school and he and Kenny rush towards the pupils. Mr Finch shrieks, summoning the other Krillitanes, who transform into their bat-forms. Mickey and Kenny meet up with the others and run into the cafeteria, pursued by the bat creatures. Finch tells them he wants the Doctor alive, but to eat the others. As the Krillitanes attack, a laser bolt shoots one of them down. K9 appears in the doorway, blaster at the ready. The Doctor tells K9 to hold them off while they retreat. However, K9's battery is failing, and Finch tells the others to ignore "the shooty dog thing" and get the others. In the physics lab, the Doctor realises that the solution is the oil. The Krillitanes have changed their physiology so often that even their own oil is toxic to them now. The Krillitanes start bashing down the door. The Doctor tells Mickey to get the children unplugged and evacuated. Kenny triggers the fire alarm, the high pitched sound hurting the bat-like ears of the Krillitanes and stunning them long enough to get past to the kitchens.

Mickey unplugs the computers and gets the children out of the school. In the kitchens, the Doctor discovers the barrels of oil are deadlock sealed. The Doctor gets the others out while he and K9 stay behind. K9 tells the Doctor that the barrels will not withstand a direct hit from its laser, but as its batteries are weak, it has to remain nearby. The Doctor protests, knowing that K9 will be caught in the explosion, but the dog replies there is no alternative. Sadly, the Doctor bids his old friend good-bye, and calls it a good dog. The Doctor takes Sarah's hand and while she asks about K9, drags her away from the school. Mr Finch and his brethren enter the kitchen in human form, searching for the Doctor. Finch mocks K9 when he sees it, but K9 shoots a barrel, spilling the toxic oil over the aliens. Finch snarls to K9 "you bad dog"; the dog replies, "Affirmative." The explosion takes out a large chunk of the school. The pupils cheer the school's destruction, and hail Kenny as the hero who did it. Sarah weeps over K9's sacrifice as the Doctor comforts her.

Later, Sarah enters the TARDIS, which is standing in a park. Rose suggests that Sarah join them, but Sarah declines, saying it is time she found a life of her own. Mickey asks if he could join them in the TARDIS. Sarah says they need a Smith aboard the TARDIS, and the Doctor agrees, although Rose does not look as pleased. Before she goes, Sarah admits that she wants to stay, but tells Rose that some things are worth getting a heart broken for. She adds that someday, if Rose needs to, to find her. Outside, Sarah thanks the Doctor for her time with him. The Doctor asks if there had been anyone special, and Sarah tells him that there was this one man, who she travelled with for a while, but he was a tough act to follow. She asks him to say good-bye this time, and he does, hugging her tightly. Sarah watches the TARDIS disappears, and as it does so, a brand new K9 is revealed. K9 explains that the Doctor rebuilt and improved it. Happily, Sarah orders K9 home. They have work to do.

Story notes

 * According to Milo, faster-than-light travel can be accomplished by harnessing a quantum tunnel with an FTL factor of 36.7 recurring.
 * Mickey Smith becomes a companion of the Doctor at the end of the episode
 * According to an interview with writer Toby Whithouse in Doctor Who Magazine #367, this episode had the working title Black Ops. The original storyline submission for the episode involved the Doctor meeting Sarah while investigating events at an army base neighbouring an isolated village. The change of location to a school was suggested by Russell T Davies.
 * This is the first time that companions from the original series of Doctor Who appear in the new series. Up to this point, there had been some debate in fandom over whether the revived Doctor Who series actually takes place in the same continuity as the 1963-89 series, despite numerous references which supported continuity; the appearances of Sarah Jane and K9 in this episode are considered several of the major pieces of evidence to support that it does (Sarah Jane, in addition, utters a line of dialogue recognizing that the TARDIS interior had been changed). Other pieces of evidence include the Journal of Impossible Things images of past Doctors in DW: Human Nature, the canonical appearance of the Fifth Doctor in DW: Time Crash, the return of Davros with direct references to Sarah Jane's involvement in DW: Genesis of the Daleks in DW: The Stolen Earth / Journey's End, the return of the Brigadier in SJA: Enemy of the Bane, the infostamp acquired by Jackson Lake on the Doctor's life in DW: The Next Doctor, and the hologram displayed by the Atraxi ship in The Eleventh Hour which shows a montage of the first ten Doctors.
 * The K9 prop used at the end of the episode is one of the original props from the 1970s.
 * Finch's unusual turn-of-phrase "Forget the shooty-dog thing" (referring to K9) strongly echoes the dialogue patterns used extensively on Joss Whedon's television series Buffy the Vampire Slayer. This is perhaps an intentional nod, as the actor who plays Finch, Anthony Head, is best known for his role as Rupert Giles on that series.
 * Even before appearing in School Reunion, Head was already connected to the Doctor Who franchise, having provided narration for Doctor Who Confidential; he has also been identified as one of several actors considered at various times to play the Doctor. After appearing in this episode he has continued to narrate Confidential and also provided the voice of Baltazar in the animated serial DW: The Infinite Quest.
 * Although strongly implied in the case of Rose since at least DW: The Parting of the Ways, and discounting the unique case of one-off companion Grace Holloway in DW: 1996 TV movie, this episode marks the first time a companion has expressed having anything beyond platonic feelings towards the Doctor. Later, Rose, Martha Jones and Jack Harkness would make their feelings known as well. In a related vein, this episode marks the first time the Doctor has explained at any length how the departure of companions affects him, although he stops short of mirroring Sarah Jane's feelings.
 * In one scene Rose and Sarah break up with laughter when The Doctor enters the room, after spending several minutes comparing notes on the Doctor. To get a realistic reaction, David Tennant wore a fake moustache (unbeknownst the actresses) as he entered the scene. Their reaction was caught in one take.
 * During the scene in the fish and chip shop when the Doctor and Sarah talk about her leaving him, 'Love Will Tear Us Apart' by Joy Division, is played in the background.
 * Although this episode marked the return of Elisabeth Sladen and Sarah Jane Smith to Doctor Who proper, Sladen had in fact been reprising the role for some time in other media. Earlier in the same month School Reunion was first broadcast, the final episode of Big Finish Productions' Sarah Jane Smith audio drama series was released, which had been going off-and-on since 2002. Sladen also reprised the role in the 1995 independent film RP: Downtime, in two early-90s BBC Radio dramas with Jon Pertwee, and had also appeared in the 1993 pastiche, DW: Dimensions in Time.
 * Sarah Jane has a Volkswagen car in this episode. In The Sarah Jane Adventures she has a Nissan Figaro.

Filming locations

 * The primary location for the school filming was Duffryn High School in Newport

Continuity

 * When Sarah and Rose argue they refer to a lot of encounters with aliens. Sarah refers to meeting:
 * Mummies (DW: Pyramids of Mars)
 * "Lots of robots" (DW: The Time Warrior, Robot, The Sontaran Experiment, The Android Invasion, and The Five Doctors, )
 * Daleks (DW: Death to the Daleks and Genesis of the Daleks)
 * Anti-matter monsters (DW: Planet of Evil)
 * Dinosaurs (DW: Invasion of the Dinosaurs)
 * The Loch Ness Monster (DW: Terror of the Zygons)


 * Rose refers to meeting:
 * Ghosts (DW: The Unquiet Dead)
 * Slitheen in 10 Downing Street (DW: Aliens of London/ World War Three)
 * Dalek Emperor (DW: The Parting of the Ways)
 * "Gas-mask zombies" (DW: The Empty Child)
 * A Werewolf (DW: Tooth and Claw)


 * The Doctor left Sarah on Earth in DW: The Hand of Fear and this story is referenced on several occasions. It is revealed that Sarah Jane was dropped off in Aberdeen (in north-east Scotland) rather than South Croydon in London. At the end time, Sarah realised that the Doctor had "goofed" and that she was not in South Croydon.
 * The Doctor left K9 Mark III with Sarah in the spin off series K9 and Company.
 * The Doctor says "Correct-a-mundo", adding "A phrase I have never used before, and will hopefully never use again." In NSA: The Feast of the Drowned he used the phrase "Ace-a-mundo", and makes an almost identical comment on it.
 * Sarah has previously encountered two incarnations of the Doctor since leaving: PDA: Bullet Time (Seventh Doctor), EDA: Interference - Book One (Eighth Doctor).
 * Sarah speaks to the Doctor of events of DW: The Christmas Invasion.
 * Rose expresses surprise that the Doctor had travelled with other companions, but in DW: The Doctor Dances he state that he has "travelled with a lot of people".
 * K9 has been called a tin dog once before, by the Time Lord Drax in DW: The Armageddon Factor.
 * Although a well-established piece of information when relating to the original series, this episode marks the first time the revived series clearly recognized on screen that incarnations prior to the Ninth Doctor existed (except for the Ninth Doctor's comment in Rose about his ears, his reference to kissing complete strangers in DW: The Long Game, the Cyberman head in DW: Dalek and referring to it as "an old enemy") (although the episode stops short of explicitly defining the current Doctor as the Tenth, only that "half a dozen" regenerations had occurred since he and Sarah Jane last met. Although that would make him the Tenth Doctor, as half a dozen plus four is ten.) Up to this episode, there was still lingering doubt in some fan circles as to whether the continuity of the revived series indeed connected with that of the 1963-89 series, and this episode is considered the turning point in firmly establishing the connection (later to be undeniably confirmed by DW: Time Crash and DW: The Next Doctor).
 * Rose complains that the Doctor leaves his companions behind after a while, but in fact, out of 32 companions, only four have been left behind, one of which got kicked out for bad behavior, another one the Doctor was terrified of, his own granddaughter whom he believed deserved a better life, and Sarah Jane Smith. All the rest died, were separated due to circumstances beyond his control, had their memories erased, or decided to leave on their own. Still, other individuals (such as Grace Holloway) were aquainted with the Doctor only for the course of the current adventure but never travelled with him as companions. However as Rose at this point is only familiar with Adam, Jack, and now Sarah Jane, her argument is accurate in this context.
 * Although not indicated on screen in this episode, nor on screen in any episode of The Sarah Jane Adventures, the novelisation of the SJA pilot episode Invasion of the Bane revealed that the Doctor left Sarah Jane a sonic lipstick and other items in a secret compartment within K9. On screen, the sonic lipstick debuts in the Invasion of the Bane episode, but no explanation is offered as to where it came from. It appeared for the first time on Doctor Who during DW: Journey's End.
