The Cyber Controller awakens to find that, since it had conditioned its brain to function in a state of reversed polarity, it is unable to function properly. Emotional memories resurface in its organic brain, and, confused and frustrated, it smashes up the rest of the base and allows Ruby and the Doctor to escape. The Doctor and Ruby flee back to the Jade Pagoda and return the crew and passengers to the Elysium. There, Ruby finds Brack dying of hypothermia, and saves his life by injecting him with the Cybermen's metabolic booster. The Jade Pagoda is about to collapse in upon itself, and as the Doctor prepares to depart, Ruby asks if she can join him. But she realises that she's left her Nanocom in the coat she draped around Brack and when she returns to reclaim it, the Pagoda dematerialises without her.
