GIRL: I'm always losing things. I lost my best pencil, my schoolbag, and my gran, and my mojo.

DOCTOR: Your mojo?

GIRL: I got it back, though.

DOCTOR: Hey, that's good.

GIRL: My mum says I shouldn't talk to strange men.

DOCTOR: Ah, you mum's right.

GIRL: Are you strange?

DOCTOR: Oh, dear. I'm way past strange. I think I'm probably incredible.
