CLARA: I'm the Doctor.

DOCTOR: Don't you dare.

CLARA [OC]: Doctor Oswald.

CLARA: But you can call me Clara.

RIGSY: I'm Rigsy. So er, what are you a doctor of?

DOCTOR: Of lies.

CLARA [OC]: Well, I'm usually quite vague about that. I think I just picked the title because it makes me sound important.

JAC: It's an odd world nowadays, isn't it?

CLARA: It's always been an odd world.

JAC: Mmm. I mean, doesn't it feel, sometimes, that things are coming to an end? Everything's just going nuts.

CLARA: You're middle-aged, that's what it is. No offence. Everybody middle-aged always thinks the world's about to come to an end. Hmm. Never does. It's here. Oh, my God.

BORS: What is it you dread?

DOCTOR: Why would I dread anything?

BORS: You're always making jokes. You never sit still, like you're running in fear of days to come.

DOCTOR: I thought you were an idiot.

BORS: I know. I thought that too.

DOCTOR: Good. I was worried I would have to break it to you
