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.

ISOBEL: You're still worried about your two friends, aren't you?

ZOE: Yes, a bit.

ISOBEL: They can't have got themselves into any sort of trouble, can they?

ZOE: Oh, you wouldn't say that if you knew them. If there's trouble to be found, the Doctor and Jamie can't miss it.

ZOE: Of course he can. The Doctor's almost as clever as I am.

DOCTOR: Goodbye, Zoe.

ZOE: Goodbye, Doctor. Will we ever meet again?

DOCTOR: Again? Now, Zoe, you and I know, time is relative, isn't it?

DOCTOR: All right, all right, I suppose you want to see my pass? Yes, well, I haven't got one. And I'm not going to tell you my name, either. Now you just tell Brigadier Lethbridge-Stewart that I want to see him. Well, don't just stand there arguing with me, man! Get on with it!

LIZ: Yes, well, he wants us to join him. 'Miss Shaw and the Doctor will report themselves forthwith to Wenley Moor. Attend a briefing meeting at precisely-'

DOCTOR: My dear Miss Shaw, I never report myself anywhere. Particularly not forthwith.

SHORT: I do hope you'll include us in your article. We've been sadly misrepresented.

SARAH: Really? Well, we're covering a number of fringe organisations, and I'm sure we'll find a place for you. Somewhere between the flying saucer people and the flat Earthers.

DOCTOR: By the time I've called look out, what's your name?

ROMANA: Romanadvoratnelundar.

DOCTOR: By the time I've called that out, you could be dead. I'll call you Romana.

ROMANA: I don't like Romana.

DOCTOR: It's either Romana or Fred.

ROMANA: All right, call me Fred.

DOCTOR: Good. Come on, Romana.

DOCTOR: Er, excuse me! What I'd like to know. Where did you get those jelly babies?

ROMANA: Same place you get them.

DOCTOR: Where?

ROMANA: Your pocket.

ROMANA: K9, what is tennis?

K9: Real, lawn or table, mistress?

ROMANA: Never mind. Forget it.

K9: Forget. Erase memory banks concerning tennis. Memory erased.

TEGAN: How do we find the index file? Of course, if we had an index file, we could look it up in the index file, under index file. What am I saying? I'm talking nonsense.

MONARCH: I have over thrown the greatest tyranny in the universe. External and internal organs.

NYSSA: What about love?

MONARCH: Love?

ENLIGHTENMENT: The exchange of two fantasies, your Majesty.

ACE: I felt like I could run forever, like I could smell the wind and feel the grass under my feet and just run forever.

DOCTOR: Still, I rather like the look of it here.

EVELYN: Oh, yes, terrific. It's cold, it's wet, it's foggy, and it definitely isn't the Galapagos Islands. We're probably in the middle of post apocalypse Bromsgrove in the ninety fifth century. If this is Earth at all.

NYSSA: I thought we couldn't change history.

DOCTOR: This place. All decay and despair. It feels like an end. Yet you and I know what's coming afterwards. So it's not an ending. Just an alternative.

NYSSA: So we can't change history.

DOCTOR: Who says? I think history's old enough to take care of itself.

ROMANA: K9 is a vicious robot criminal from the fifth galaxy. Aren’t you, K9?

K9: Affirmative!

ROMANA: Leela. Are you saying you’re afraid of me?

LEELA: You are also two people. The person I know, and the person you once were. Who

is… so different.

ROMANA: You’ve always known I was a Time Lord. Regeneration is a natural part of the

progression of our lives. Completely without consequence.

LEELA: One person cannot become many without consequence.

JAMIE: What the Doctor said... it was true. All of it. I've seen such wonders! I've walked on the moon. I've watched Atlantis sink beneath the waves. I've been to the other side of space and back again. And everywhere we went, there were monsters.

STRAX: And how will she locate the Doctor?

VASTRA: To find him, she needs only ignore all keep-out signs, go through every locked door, and run towards any form of danger that presents itself.

STRAX: Business as usual, then.

VASTRA: Business as usual.

GREGSON: Well, it's just laid an egg.

VASTRA: It's dropped a blue box marked Police out of its mouth. Your grasp of biology, it troubles me.

CLARA: If Vastra changed, if she was different, if she wasn't the person that you liked?

Jenny: I don't like her, ma'am. I love her. And as to different? Well, she's a lizard.

DOCTOR: Blaming the Universe is the only way I can get out of bed in the morning.
