DOCTOR: Logic, my dear Zoe, merely enables one to be wrong with authority.

ZOE: I don't want to be thought of as a freak. Leo said I was like a robot, a machine. I think he's right. My head's been pumped full of facts and figures which I reel out automatically when needed, but, well, I want to feel things as well.

JAMIE: You're just not trained for an emergency like this.

ZOE: Well, that's the whole point. What good am I? I've been created for some false kind of existence where only known kinds of emergencies are catered for. Well, what good is that to me now?

JAMIE: Hey, we're not done yet, you know.

ZOE: And if we survive? What then, Jamie? Suppose we do get ourselves out of this mess. What have I got left? A blind reliance on facts and logic.

CORWYN: Thank you. And your friend?

JAMIE: Er, the Doctor

.

CORWYN: I can't put that down.

JAMIE: Er. John Smith.

CORWYN: Really?

JAMIE: Aye.
