- Clara: [on the phone] You're always showing me amazing things. Well, I, Doctor, have finally got something amazing to show you.
- The Doctor: Yes, well, there are some things that I've never seen, but that's usually because I've chosen not to see them. Even my incredibly long life is too short for Les Miserables.
- [first lines]
- Maebh: I'm lost. Please, can you help me?
- The Doctor: [pointing in a random direction] It's that way.
- [starts to close the door, but sees trees all around the Tardis]
- The Doctor: Are those trees?
- Maebh: I need the Doctor. Are you the Doctor?
- The Doctor: Yes. Do you have an appointment? You need an appointment to see the Doctor.
- The Doctor: When you drink a glass of Coke, it's only this big,
- [gestures with his hands]
- The Doctor: but it's actually got this much sugar
- [opens arms wide]
- The Doctor: in it. It works a bit like that.
- Maebh: What does?
- The Doctor: The Tardis. It's bigger on the inside than the outside. Or did you not notice?
- Maebh: I just thought it was supposed to be bigger on the inside, so I didn't say anything.
- Danny: [pointing to the top of a Geometry diagram] How do we find "X"? Ruby?
- Ruby: It's there sir, at the top.
- Danny: No, how do we find...
- Ruby: It's not lost. It's there, at the top, look!
- Danny: No, how do we find the value of "X"?
- Ruby: Why are you asking me all the questions? Give someone else a go.
- Clara: Look, is she alright? Would you bring her over?
- The Doctor: I can't bring her over. I'm a Time Lord, not a child minder!
- Clara: You've got a spaceship, all we've got are oyster cards.
