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.

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.
