IAN: Susan Foreman? She's a genius! (BARBARA rolls her eyes, and the two teachers get up to leave.) BARBARA: Who? SUSAN: You are surprising, Mr. Chesterton. IAN: Too stupid...or just doesn't know. There she is! IAN: I take things as they come, come on. Feel it! (He faces them again.) Various antiques decorate the place. (The DOCTOR takes an electronic object out of his pocket and walks to the console. A thing that looks like a police box, standing in a junkyard...it can move anywhere in time and space!? DOCTOR: (He puts his hands on SUSAN'S shoulders.) (The DOCTOR laughs.) SUSAN: Grandfather, let them go now! Hold it...
(The shaking worsens, and the teachers are flung across the room, BARBARA into a chair and IAN onto the floor - a raucous grinding engine sound rises and falls through the room, the cylindrical column begins to rise and fall. TARDIS.
