MISSY: I am your friend.

DOCTOR: Makes no difference.

MISSY: I know it doesn't. I know I'm going to die. I have to say it, the truth. Without hope. Without witness. Without reward. I am your friend.

DOCTOR: Do you know a girl called Penny?

BILL: Well, yeah.

DOCTOR: What's she like?

BILL: Out of my league.

DOCTOR: No.

BILL: Sorry, what? No?

DOCTOR: No.

BILL: What does that mean, no?

DOCTOR: It means I'm a scary, handsome genius from space and I'm telling you no, she's not out of your league.
