- The Doctor: Running away with a spaceman in a box, anything could happen to you.
- Clara: That's what I'm counting on.
- Bram Van Baalen: You crazy lunatic!
- The Doctor: My ship, my rules!
- Gregor Van Baalen: You'll kill us all! And the girl.
- The Doctor: She''s going to die if you don't help me. Don't get into a spaceship with a madman. Didn't anyone ever teach you that?
- The Doctor: There is no self-destruct. Hey? Hey? Hey? Had you going, though, boys, didn't I? I just wiggled a few buttons. Yeah, the old wiggly button trick. And the face. You've got to do the face.
- [in a mock serious tone]
- The Doctor: "Save her or we all die."
- Clara: The library. I saw it. You were mentioned in a book.
- The Doctor: I'm mentioned in a lot of books.
- Clara: You call yourself Doctor. Why do you do that? You have a name. I've seen it in one corner of that tiny...
- The Doctor: [shushing her] If I rewrite today, you won't remember. You won't go looking for my name.
- Clara: I always feel so safe after we've spoken.
- The Doctor: Marvelous. Keep this door shut.
- Clara: That will NOT be a problem.
- Clara: [after escaping from the creature] What do you keep in here? Why have you got zombie creatures? Good guys do not have zombie creatures. Rule one, basic story telling!
- [Bram separates a section of the TARDIS console. Voices from the past start leaking out and overlapping each other]
- Susan Foreman: [as said to Ian and Barbara] Well, I made up the name TARDIS from the initials: Time And Relative Dimension In Space.
- The Doctor: ...dimensionally transcendental.
- Jo Grant: What's that mean?
- The Doctor: You sexy thing!
- Idris: See, you do call me that! Is it my name?
- The Doctor: You bet it's your name!
- The Doctor: [as said to Leela] That's trans-dimensional engineering. A key Time Lord discovery.
- The Doctor: [as said to Rose Tyler] The assembled hordes of Genghis Khan couldn't get through that door, and, believe me, they've tried.
- Martha Jones: It's just a box...
- Amy Pond: We are in space!
- Martha Jones: ...with that room crammed in!
- Ian Chesterton: That thing that looks like a Police Box, standing in a junkyard, it can move anywhere in time and space?
- Clara: [reading from "The History of the Time War" in the Tardis library] So that's who...
- [she's interrupted by a creature growling behind her]
- Gregor Van Baalen: What makes you think we'll help?
- The Doctor: [throws a few switches and a countdown appears on the monitor] I just activated the Tardis self-destruct system. One hour until this ship blows. Don't try to leave. The Tardis is in lockdown. I'll open those doors when Clara's by my side.
