Helen Sinclair

Helen Sinclair was a companion of the Eighth Doctor.

Early life
Helen Sinclair was born in England around 1933. (AUDIO: The Red Lady) She had two brothers; Harry, whom she did not always get along with, and George. As a young woman, her father was cruel and acted as a bully to both her and her mother, which Helen attributed to their gender as her brothers did not receive the same treatment. (AUDIO: Absent Friends)

Both Helen and George thought that their aunt Phyllis's cat was evil as it hissed and scratched a lot, but she later learnt that it was sick and in pain and would allow Helen to stroke it if she was gentle. She found the cat's purring rewarding. (AUDIO: World of Damnation)

Her grandmother suffered from a terminal disease, which Helen took some time to come to terms with. After she died, Helen found that she could only recall when her grandmother first told the family that she was sick and not when she told them that it was terminal. (AUDIO: Ship in a Bottle)

Helen's only time spent outside of Great Britain was a camping holiday to Jersey. (AUDIO: The Galileo Trap)

Career
Helen worked as a specialist in translation in the National Museum's Department of Linguistics (AUDIO: Ship in a Bottle) and became assistant to Professor Walter Pritchett, with whom she shared a fond relationship. (AUDIO: The Red Lady) She commuted by bus from her home in Tooting and was often late. (AUDIO: The Galileo Trap)

Despite being more qualified and having worked at the museum four years longer, Helen was passed over for a promotion in 1963 by Professor Garland, who promoted Timothy instead. She correctly determined that the appointment was due to her gender, which was confirmed by Professor Garland. Whilst Professor Pritchett expressed his sympathies, he was happy not to have lost his assistant. (AUDIO: The Red Lady)

Meeting the Doctor and Liv
In 1963, Helen was given some of Dr Francis McCallum's papers to translate and met the Eighth Doctor and Liv Chenka, who broke into her office in search of a tablet that she was working on deciphering. She eventually joined the pair in investigating the Red Lady, in the course of which Professor Pritchett died. Once it was resolved, Helen was fired by Professor Garland for the unexplained disappearance of McCallum's collection and joined the Doctor and Liv in the TARDIS, suspecting that the police would be on her doorstep the following day. (AUDIO: The Red Lady)

The trio travelled to Florence in 1639 due to Helen's tablet being a message for the Doctor from Galileo Galilei. She was excited by her newfound ability to read Latin. She and Liv joined Cavalli 2 in investigating Cleaver and his spaceship, later helping the Doctor defeat both Cleaver and Fortuna. Galileo encouraged Helen to continue travelling with the Doctor, which she chose to do when given the offer to return home instead of going after the Eleven. (AUDIO: The Galileo Trap)

On Phaiton, Helen and Liv were put to work cooking and cleaning by the Orbs. They managed to slip away but were caught by the Eleven, who was convinced by the Eight to keep them alive whilst the Doctor was at large. Helen was to be dissected by an Orb once the Doctor was captured, but she was saved by Paine and escaped with Liv to the TARDIS, which dematerialised and rescued the Doctor. With the Eleven defeated, the Doctor told Helen and Liv that they needed a holiday. (AUDIO: The Satanic Mill)

Freeing the Sonomancer
After this ordeal, the Doctor took her and Liv to Stegmoor to recuperate. She wanted to go somewhere a bit more alien. She helped to move the Doctor when he fell unconscious. She told the Doctor about the Voord spaceship on the beach. (AUDIO: Beachhead) She couldn't understand the dimensions of the antique TARDIS. Caleera used her powers to empathise with her. (AUDIO: Scenes From Her Life)

When they landed in San Francisco in 1906, Liv trusted her to guide her around the city as it was closer to her time than Liv's. She was taken by Aldo Deluca because he wanted to know about the Gift. (AUDIO: The Gift)

On Syra, Ruslan tried to threaten her into telling the truth and then trapped her with River Song. She helped River to contact Galactic Heritage. Because they were not to meet until much later in his lifetime, Helen promised to keep River's existence secret from the Doctor. (AUDIO: The Sonomancer)

Defeating the Doom Coalition
When she realised they had landed in Calcot in 1998, she decided to take a train back to London to discover what had happened to her friends and family. In London, she went to her old house and found out that it had been converted into flats. She later went to see her brother George Sinclair. George then told her about how their mother, father and brother had died, as well as how the suspicions of her role in the "theft" had tainted the family reputation so significantly that George's fiancé had left him. After asking the Doctor to take her back, he told her this was impossible. She was now part of events and could not go back and change her own timeline. (AUDIO: Absent Friends)

She was sent by the Doctor to Rome in 2016 in order to find a piece of the Doomsday Chronometer. She met Rosalia who showed her the collection of clocks in the museum she worked with. There she met the Clocksmith. (AUDIO: The Eighth Piece)

Before entering the museum, she met River again, who told her to come with her on a scavenger hunt to help her find the Eighth Piece. She collected many paintings and discovered where the Eighth piece was and took it back to Rome. She was then frozen in time for the Clocksmith's enjoyment before the Doctor arrived. She managed to escape the collapsing museum and went back to the TARDIS just in time to see Whitley regenerate. (AUDIO: The Doomsday Chronometer)

Liv had to explain the effects of regeneration to her after witnessing it. After the Nine told her that Liv had died on Gallifrey, she wanted to leave and she couldn't believe the man she thought was the Doctor had just left, before she discovered that he was the Nine, an earlier incarnation of the Eleven. She was appalled at the Nine murdering the Time Lords at the Crucible of Souls. Padrac then revealed he was working with the Eleven, and trapped her, Liv and the Doctor in a scape capsule careering into the nontime of a murdered future by Padrac. (AUDIO: The Crucible of Souls)

The group tried to head back to the Crucible in an attempt to stop Padrac, but the capsule proved to be locked on a fixed course. After seeing some pressure suits she thought of jumping out and swimming in the other direction. She tried to calm Liv down after she became upset. They jumped out of the pod and rode the shockwave back into normal time. (AUDIO: Ship in a Bottle)

Liv and Helen appeared back in the normal universe with only five minutes of oxygen. They were rescued by a Time Ship which traversed the vortex and started to disintegrate. After Liv managed to get them to Earth she wanted to get to a spaceport to get away from an Earth which was disintegrating. River later told Helen to tell Liv who she was. River managed to get her to Gallifrey where she got to the TARDIS and left with Veklin to find the Doctor. (AUDIO: Songs of Love)

Helen and Liv went exploring New York. When they went to the main museum they saw a picture of the TARDIS and a Weeping Angel which had been bequeathed by them. At the museum they started to hear about the Weeping Angels. projected an angel which then became an angel in front of them. However, they were saved by Veklin. They joined up with the Doctor again, but the Eleven trapped them on top of a skyscraper. The Monk was sent back in time and Ollistra was pushed off the building, causing a regeneration, but the Doctor, Liv and Helen managed to get away to the TARDIS and headed back for Gallifrey to finally stop Padrac before his plans succeeded. (AUDIO: The Side of the Angels)

The group headed to Gallifrey. Helen wanted to join the Doctor in the Panopticon but he wouldn't let her, instead she was tasked in evacuating the Time Lords. When the Eleven escaped from his restraints he stole a Battle TARDIS and kidnapped her. Caleera contacted her via the Matrix, granting Helen the telekinetic powers of the Sonomancer. She was able to stop the blast from the Eleven's staser with her mind. Caleera got her to crash the TARDIS into the Resonance Engine to defeat the Doom Coalition. The Battle TARDIS was not destroyed in the blast, so the Doctor and Liv went searching for it. (AUDIO: Stop the Clock)

Reunion with the Doctor and Liv
The Battle TARDIS crash landed on Rykerzon, and Helen and the Eleven were taken as prisoners. During that time, Helen cared for the Eleven and tried to help him control his condition and suppress the voices of his other incarnations. She would sing to soothe him, and he pretended to reciprocate, and called her his saviour. When the Eighth Doctor and Liv arrived looking for Helen, she was thrilled to see them again, despite the Doctor being sceptical of her. Eventually, the Eleven joined with the Kandyman to take over Colony 23, a plan which was then stopped by the Doctor, Liv and Helen. Helen was then welcomed back on board the TARDIS. (AUDIO: World of Damnation, Sweet Salvation)

After re-joining the TARDIS, Helen continued travelling with the Doctor and Liv. During this time, they took a trip to Liv's home world, Kaldor. (AUDIO: Escape from Kaldor)

After the Doctor was dragged into hell in an unfavourable trip to Salzburg, Helen spent decades trying to pilot the TARDIS. After bringing a notable saint to Salzburg to save the day, she was on the brink of death, having aged considerably in the time she spent trying to figure out how to control the TARDIS. Liv remembered the Wish Granter's cryptic quote and realised that she could use his powers to restore Helen to her old self. (AUDIO: Better Watch Out, Fairytale of Salzburg)

Stranded in 2020
After escaping the collapsing console room, Helen, Liv and the Doctor moved into 107 Baker Street. Helen was told by the Curator, whom she met twice before following him to the Under Gallery, that she and Liv had to make sure to look after the Doctor. (AUDIO: Lost Property) She gave Robin Bright-Thompson some tuition in history and decided to become a tutor.

Helen witnessed a robber leaving Sanjit's convenience store and found that Liv had been shot before giving chase. She apologised to DCI Treadwell for the Doctor's behaviour and involvement in the case and, after the man was caught, she encouraged the Doctor not to give up on the TARDIS nor on living his life. (AUDIO: Wild Animals)

Helen helped the Doctor investigate the extraterrestrial surveillance of the house and Mr Bird after they became suspicious of him. (AUDIO: Must-See TV)

After the Doctor won You Either Know It or You Don't, Helen and Liv convinced him to invest the £80,000 on the house rather than towards his efforts to restore the TARDIS. She took Robin shopping and attempted to discourage his interest in Divine Intervention, whose representative, Rafaella Hicks, told her that she was unsuited for. She was present when the TARDIS was partially-restored and the Doctor told her that they would soon take it for a test drive. (AUDIO: Divine Intervention)

Personality
Helen was intelligent, sceptical and willing to admit when she was wrong. (AUDIO: The Red Lady) She was compassionate, which could sometimes allow her to be manipulated, (AUDIO: The Gift, World of Damnation) and trusting, to the extent that she did not tell Liv or the Doctor about River Song's identity. (AUDIO: The Sonomancer, Songs of Love) She was sensible, except when running from the law. (AUDIO: World of Damnation)

She felt that society had never allowed her to be the best that she could be and was pleased that her strengths were celebrated rather than feared whilst travelling with the Doctor. (AUDIO: Scenes From Her Life) She wanted to be successful to spite her father. (AUDIO: Absent Friends) She sometimes felt redundant next to the Doctor and Liv, but Liv assured her that she had more than proved herself. (AUDIO: Ship in a Bottle)

Above all else, Helen admired lexicology and linguistics. (AUDIO: L.E.G.E.N.D.)

Behind the scenes
In the behind the scenes extras to Doom Coalition 1, producer David Richardson cites Doctor Who's first producer Verity Lambert, (BFX Doom Coalition 1) who at the time was BBC's youngest ever and first female producer,  as a source of inspiration for the character of Helen Sinclair. This is acknowledged through Helen's coming from 1963, the same year that Doctor Who first aired. (BFX Doom Coalition 1)
