The Doctor: Picture the biggest ship you've ever seen. Are you picturing it?
Salvager: Yeah.
The Doctor: Good. Now forget it. Because this ship is infinite.

Well? Come on then. Eat up. You're full? I expect so. Because there's quite a difference between what was and what should have been. There's an awful lot of one but there's an infinity of the other. An infinity is too much, even for your appetite.

Doctor Who: I do!!

You're both good men. You just forget it sometimes.

Clara

The Doctor: Clara? You asked me what we're going to do, I told ya. We're going to go to hell, or wherever it is people go when they die, if there is anywhere. Whatever it is we're gonna go there and we're gonna find Danny. And if it is in any way possible, we're going to bring him home. Every culture has a concept of an afterlife. I always meant to have a look around, see if I could find one.
Clara: You're going to help me?
The Doctor: Well, why wouldn't I help you?
Clara: Because of what I just did, I just...
The Doctor: You betrayed me. You betrayed our trust, you betrayed our friendship, you betrayed everything that I've ever stood for. You let me down!
