Susan Foreman

Susan Foreman is the first known companion to travel with the Doctor. Susan appears to have taken her surname from the Owner of the Junkyard the TARDIS lands in during the 20th Century, I.M. Foreman. Susan is the Doctor's granddaughter, and has been travelling with him since he left Gallifrey.

Biography
Susan appears to be a typical teenage girl, and insisted – despite the Doctor’s reservations – to go to school at Coal Hill School. Her grandfather is proved right in his reservations as her knowledge is noticed by her teachers – her comments to Barbara Wright about the inaccuracies of the French Revolution text book being just one such incident. She, like all teenagers, loves pop music, but despite in general passing as an ordinary teenage girl, Susan’s alienness is hinted at in the fact that she read the thick French Revolution text book in just one evening.

Amongst Susan’s character traits are her ability, under certain circumstances, to communicate telepathically – as seen when the travellers meet the Sensorites. She’s an adventurer, and braves the petrified jungle and mutated Thals to get the anti-radiation drugs the travellers need while they are on the planet Skaro.

When Barbara and Ian Chesterton first meet Susan, she’s enjoying ‘normal’ life, and over their adventures together she grows up. Initially Susan has a crush on Ian, although this passes, and she grows to see Barbara as her mature confidente. Ultimately Susan falls in love with freedom fighter David Campbell on Earth in the 22nd Century.

Throughout her travels Susan mentions other planets she has visited – the ‘metal seas of Venus’, the planet Esto (where plants communicate telepathically) – and talks of her own planet. She tells Ping-Cho that her home is “as far away as a night star”. She also describes her planet to the Sensorite leader. She is obviously home-sick.

The Doctor realises that Susan will never leave him of her own free will, as she believes that he’s dependant on her. So, in an emotional move, he locks her out of the TARDIS and promises that one day he’ll return. On this goodbye he leaves her to finally find a place she can belong, and the home which she confides to David she has never really had.

After her grandfather left her on Earth with David, Susan settled down to marry and be a wife in the new order. She was, with others of the rebel group, a founder of the reborn human race on Earth. Finally she had the home, and family, she’d never known before.

Susan crossed paths with her grandfather again, 20 years after they’d parted company. Borusa collected Susan in a time scoop, and placed her with her grandfather, in his first incarnation, in the Death Zone on Gallifrey. After Borusa was defeated by The Five Doctors Susan was returned to her home.

''The Doctor first met Susan (from his perspective) during a visit to Ancient Gallifrey; she recognized him as her grandfather, who had come to rescue her from the breakdown of society during that era. She appeared to have been one of the last children born on Gallifrey before the Pythia's Curse, and to have been the Other's granddaughter. ''(Lungbarrow)
