The Doctor: Okay. Uh, same time you left, same place... ish.
Clara: "Ish"? Don't give me an "ish."
The Doctor: These readings are very, uh... ish-y
The Doctor: Impressive.
Clara: No, not impressive. Annoying.
The Doctor: No, this is impressive. (points at Clara) This is annoying. The TARDIS never does this. This is huge! Well, not literally huge. Slightly smaller than usual. Which is huge.
Clara: Yes, I get it, you're excited. When can I go home?
The Doctor: Could you not just let me enjoy this moment of not knowing something? It happens so rarely.
Clara: I'm, umm... I'm the Doctor.
The Doctor: Don't you dare.
Clara: Doctor Oswald. But you can call me Clara.
Rigsy: I'm Rigsy. So, uh, what are you a doctor of?
The Doctor: Of lies.
Clara: Well, I'm usually quite vague about that. I think I just picked the title because it makes me sound important.
The Doctor: Why, Doctor Oswald, you are hilarious.
Clara: Oh, sorry, I'm talking to someone else who's listening in. Doctor, Rigsy. Rigsy, Doctor.
The Doctor: Hello, barely sentient local.
The Doctor: This explains everything. Their from a universe with only two dimensions. And yes, that is a thing! It's long been theorized, of course, but no one could go there and prove its existence without a heck of a diet.
The Doctor: Congratulations, lying is a vital survival skill.
Clara: Well, there you go.
The Doctor: And a terrible habit.
The Doctor: So what's next, Doctor Clara?
Clara: Lie to them.
The Doctor: What?
Clara: Lie to them. Give them hope. Tell them they're all going to be fine. Isn't that what you would do?
The Doctor: In a manner of speaking. It's--it's true that people with hope tend to run faster, whereas people who think they're doomed...
Clara: Dawdle. End up dead.
The Doctor: So that's what I sound like.
Clara: Rule number one of being the Doctor: use your enemy's power against them.
The Doctor: I tried to talk, I want you to remember that. I tried to reach out, I tried to understand you. But I think that you understand us perfectly. And I think that you just don't care. And I don't know whether you are here to invade, infiltrate, or just replace us. I don't suppose ti really matters now. You are monsters. That is the role you seem determined to play, so it seems that I must play mine. The man who stops the monsters. I'm sending you back to your own dimension. Who knows? Some of you may even survive the trip. And if you do, remember this. You are not welcome here. This plane is protected. I am the Doctor, and I name you the Boneless!
The Doctor: Ah, the return of the fluorescent pudding brain.
Clara: Do you realize he can hear you now?
The Doctor: I know.
Clara: Come on, why can't you say it? I was the Doctor and I was good.
The Doctor: You were an exceptional Doctor, Clara.
Clara: Thank you.
The Doctor: Goodness had nothing to do with it.
