HELEN: Does that mean the woman that captured me was working for them? For the Masters?

DOCTOR: Could be, maybe The Rani? He partnered with her once.

LIV: The Rani?

DOCTOR: Another old school friend of mine. Also evil.

LIV: What were they teaching you at your school?

CHARLEY: Come on. Take my hand.

DOCTOR: But we can see now. We don’t need to hold on to each other.

CHARLEY: I know. Take my hand anyway.

DOCTOR: Cheer up. Look, there's a mouse.

CHARLEY: I am deeply cheered.

DOCTOR: (Blithely) Yes, I imagine so. It's quite clear that Frederick brought the car into the house, ran himself over with it, and put it back outside before he finally expired

COMPASSION: Remember that the Doctor isn't perfect, either.

FITZ: I know that.

COMPASSION: You dote on the Doctor, Fitz. You haven't worked it out yet, how he tolerates us. Humans are just the Time Lords' embarrassing relations. Isn't it how you'd feel if you had to travel round with only the inferior species for company?

FITZ: You make us sound like pets. Is that your big idea, Compassion? We're the Doctor's pets?

COMPASSION: Yes. But it's like the difference between cats and dogs. A dog thinks, My owner loves me and feeds me and takes care of me, so he must be god. A cat thinks, My owner loves me and feeds me and takes care of me so I must be god. He's got you to sit up and beg, like a well-trained dog. Well, he won't change me.

I.M. FOREMAN: You’ve never been a woman, have you?

DOCTOR: I’m not sure I’ve ever even been a man.
