This alcohol-addled female Doctor escaped the Time Lords (DW: The War Games), and now lifes on Earth and works at Sainburys. She abandoned her TARDIS outside a small village in the southwest of England.
Two Time Lords are sent to capture and return The Doctor to Gallifrey for sentence. They do this and inform the Doctor that her means of escape has embarrassed their superiors, as has the fact that she did so by changing gender. They’d originally intended to sentence the Doctor to exile on Earth, but now sentence her to be confined to her TARDIS for the rest of her life; if she tries to escape, her ship will dematerialise forever, and it will be as if she never existed.
As there are no guards available to take the Doctor back to her TARDIS, she politely sees herself back. The Doctor enters the TARDIS to find a note from a young Time Lord claiming that he sympathises with her and is giving her the opportunity to escape with little fuss. The Doctor operates the TARDIS controls, but as it begins to dematerialise, it occurs to her a moment too late to wonder whether he was telling the truth.
