Rose visits Sally and overhears her talking to one of the robots. Rose is horrified to realize that Sally is actually a robot, and that she and the other three are all surviving members of Glint's crew. She hears footsteps, and hurries to hide in a cupboard. She gets out, opens the door further down, and sees Jimm curled into a small ball. Sally comes out, and Rose tries to be casual as she leaves, and then runs down to tell the Doctor. He tells Dugg to barricade the door. Sally threatens them from the other side, and gives them a few minutes to decide what to do. The Doctor creates a diversion quickly, and they let Sally and the other robots come in with Jimm.
