The Doctor meets Jan and realises that he is really in love with Ace. Seemingly making his mind up about something, the Doctor enters Puterspace, only to be attacked by Phaedrus and members of the Church of the Vacuum and trapped in a recreation of his third regeneration, where he was dying of radiation poisoning, alone in the TARDIS. Ace breaks in to rescue him and the scene shifts to a recreation of Ace's home and one of her arguments with her mother. Suddenly, Julian appears and Ace realises that he has been absorbed intyo the alien's group consciousness. With the help of Christopher, whose mind still lives on inside Puterspace despite the death of his body, Julian regains enough of his individuality to help Ace and the Doctor escape. In the confusion, Phaedrus is trapped in his own worst memory, of the time when he performed the mercy killing of his dying mother.
