SARAH JANE: Doctor, you're being childish.

DOCTOR: Well of course I am. There's no point in being grown up if you can't be childish sometimes.

“Because every time you see them happy you remember how sad they’re going to be. And it breaks your heart. Because what’s the point in them being happy if they’re going to be sad later? The answer is, of course, because they are going to be sad later.”

“A straight line may be the shortest distance between two points, but it is by no means the most interesting.”

“Logic, my dear Zoe, merely enables one to be wrong with authority.”

“The very powerful and the very stupid have one thing in common. They don’t alter their views to fit the facts, they alter the facts to fit their views. Which can be uncomfortable if you happen to be one of the facts that needs altering.”

“Our lives are different to anybody else’s. That’s the exciting thing. There’s nobody in the universe can do what we’re doing.”

“Anybody remotely interesting is mad in some way or another.”

“Optimism. Belief that everything will work out well. Irrational, bordering on insane.”

DOCTOR: You think it'll last forever, people and cars and concrete, but it won't. One day it's all gone. Even the sky. My planet's gone. It's dead. It burned like the Earth. It's just rocks and dust before its time.

ROSE: What happened?

DOCTOR: There was a war and we lost.

ROSE: A war with who? What about your people?

DOCTOR: I'm a Time Lord. I'm the last of the Time Lords. They're all gone. I'm the only survivor. I'm left travelling on my own 'cos there's no one else.

ROSE: There's me.

“Good evening. I'm a Lizard Woman from the Dawn of Time, and this is my wife.”

RIVER: Does sarcasm help?

DOCTOR: Wouldn't it be a great universe if it did?

DOCTOR: Times end, River, because they have to. Because there's no such thing as happy ever after. It's just a lie we tell ourselves because the truth is so hard.

RIVER: No, Doctor, you're wrong. Happy ever after doesn't mean forever. It just means time. A little time. But that's not the sort of thing you could ever understand, is it?

“But you can't rewrite history! Not one line!”

“It felt cruel... to be shown something I couldn't have any more. Felt like, er, I'd rather not have known. I'd rather not have met her, cos having met her and then... being without her, that's worse. How do you deal with that?”

LIZ: Then what do you do, exactly?

BRIGADIER: We deal with the odd, the unexplained, anything on Earth, or even beyond.

LIZ: Alien invaders? Little blue men with three heads?

BRIGADIER: Ten tons of alien material drift through space and land on this planet every day.

LIZ: And do no harm to anyone.

JAMIE: Doctor, come on, will ye? The whole place is going to blow up.

DOCTOR: Oh, it's quite all right, Jamie. The planet is quite safe. There's just going to be a localised volcanic eruption. It'll only affect the island.

JAMIE: Maybe so, but we happen to be on the island.

DOCTOR: Oh, my word!

LEELA: I was so alone in the world of dreams when you left… The wildlands were dark and so quiet. I… I do not wish to be alone.

ROMANA: There will be a place for you with me. For always. Whatever face I wear.

“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: 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.

“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!”

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.

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.

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.

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.

“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.”

“Blaming the Universe is the only way I can get out of bed in the morning.”

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.

“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?

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.

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.

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.

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.

K9: This unit does not have feelings, mistress.

LEELA: That is untrue, K9. Many times you and the other K9–

K9: Neither K9 unit possesses feelings, mistress.

LEELA: You should not be afraid of your feelings, K9.

ROMANA: Yes, thank you. If we can move on from the emotional support group session?

“I'm being set up! Again! It's obvious. Why would I help you if I was the terrorist? I'm being set up, I tell you. Surely even you can see that. You can't let her stab me, K9, it's not legal!”

“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.
