Notes from wiki
Rachel Talalay Steven Moffat 1 July 2017 TBD 83
Escaping to the next floor of the ship, the Doctor tries to comfort Bill, who has retained her humanity, though this is wearing thin. This floor of the ship is a simulated countryside, where the group helps defend the villagers from the oncoming Cybermen. Knowing they are overwhelmed, the Doctor attempts to convince Missy and the Master to help him. They refuse, though Missy seems conflicted. Hoping to save the villagers, the Doctor tells Nardole to take them to another floor while he sacrifices himself. Bill opts to stay with the Doctor, and Nardole says goodbye, taking the villagers to safety. Elsewhere, before escaping to their TARDIS, Missy betrays the Master to help the Doctor by stabbing him in the back, triggering the regeneration process. He shoots her in return, killing her. The Doctor fights off the Cybermen, but is shot by the now fully-converted Bill. He proceeds to blow up the whole floor, killing himself. Bill somehow survives, with Heather appearing before her. They kiss, and Heather reveals she changed Bill into her species so she could live on. The two take the Doctor back to his TARDIS, Bill using her species' healing powers to bring him back before she and Heather leave to see the universe together. The Doctor awakens as the regeneration process begins. He refuses, attempting to stop it, and exits the TARDIS onto an icy planet, where he is greeted by the First Doctor.
