DOCTOR: This world is uninhabited. Nobody lives here and – so far – nobody has ever lived here. There’s wildlife, yes, but nobody that could look up and say, “Look at those five stars over there. They remind me of that weird fish I saw in the river the other day.

RUBY: They don’t look anything like a fish. They look like a slipper.

DOCTOR: That’s something else that hasn’t happened before

RUBY: What?

DOCTOR: People arguing about what’s right in front of them. Next one of us will start a religion worshipping the Great Fish of the Stars and the other will declare themselves a follower of the Celestial Bedsock and, before we know it, the world’ll go to hell in a handbag

DOCTOR: But there is one thing that I should warn you about, Ruby, and this is really very serious. With all of my adventures throughout Time and Space, I have to tell you there is always a twist at the end.

DOCTOR: I thought that was non-diegetic.

‘The Saga of the Time Lords,’ Rose repeated, as the play’s title flashed up once again. ‘Isn’t this a bit like watching a home movie for you?’ She looked around. ‘With really high production values?’

‘From what I’ve heard, it’s more like fan fiction,’ the Doctor said. ‘And don’t get me wrong. I love fan fiction. You should read some of mine. But I sincerely doubt anybody here has ever actually met a Time Lord, let alone been to Gallifrey.’

DOCTOR: Never be cruel. Never be cowardly. Hate is always foolish. Love is always wise. Always try to be nice, but never fail to be kind.

BILL: So, the Time Lords, bit flexible on the whole man-woman thing, then, yeah?

DOCTOR: We're the most civilised civilisation in the universe. We're billions of years beyond your petty human obsession with gender and its associated stereotypes.

BILL: But you still call yourselves Time Lords?

DOCTOR: Yeah. Shut up.

GABBY: When the TARDIS “blasts off”, it makes a noise like an elephant and a piano bringing sexy back.

DOCTOR: The way I see it, every life is a pile of good things and bad things. The good things don’t always soften the bad things, but vice versa, the bad things don’t always spoil the good things or make them unimportant.

DOCTOR: You know when grown-ups tell you everything's going to be fine and you think they're probably lying to make you feel better?

AMELIA: Yes.

DOCTOR: Everything's going to be fine.

AMY: You're worse than my aunt.

DOCTOR: I'm the Doctor. I'm worse than everybody's aunt.

DOCTOR: Hello. I'm the Doctor. Basically, run.

SARAH: So there's three of you?

ROSE: Three Doctors?

JACK: I can't tell you what I'm thinking right now.

DOCTOR: Everybody lives, Rose. Just this once, everybody lives!

DOCTOR: Confusing, isn’t it? When you don’t know who the bad guys are.

GILBROOK: My great-grandfather was just a kid, working in the fields when it happened.

BRODLIK: When what happened?

GILBROOK: Fields. Can you imagine that? Huge areas of land where crops would grow. Crops that could feed dozens of people. And my great-granddad. He looked up into the sky. And so he told his son, and so he told my dad. He saw that Koteem ship explode. He saw it… He said it was like paint spilling across a table. It seemed that fast… He said.. He said it was almost beautiful.

DOCTOR: It’s all a matter of perspective, isn’t it?

DOCTOR: As for making a difference, I don’t think we really influenced anything at all.

DOCTOR: Sometimes, if you stare at a painting for too long and get too close to it, all you can see are the brushstrokes. The harder you stare, the more formless and meaningless it seems to become.

NYSSA: And that’s your analogy for the whole of the universe, is it? A painting you don’t want to look at too closely in case it doesn’t mean anything?

DOCTOR: I don’t know. Sometimes I think of it that way, yes.

DOCTOR: We need to end the story.

EVELYN: Why? Stories don't end in real life. Sally was right. There's no happy ever after. There's happy, and then there's the day after, which might be happy, and then the day after, which might be happy, but keep on going far enough and you'll get to a day which isn't. There's never a final end.

SALLY: Oh, there is.

DOCTOR: No, Sally. That's the wonderful thing about life. You can't rule a neat line under it. But individual stories can end—and then you move on to the next one. It might be a better story or a worse one. It might be a sequel to something you've done before. The important thing is, that they're your stories. And no one can take that away from you.

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

CHARLEY: I am deeply cheered.

ELIZA: We don’t have to go back to our own times, though. We could go back to the age of the dinosaurs or something.

JUSTINE: Why would we want to do that?

ELIZA: I don’t know. It’d just be interesting. You know. We could start our own Faction Paradox mission there. In the middle of the Jurassic or wherever.

JUSTINE: A mission?

ELIZA: Yeah, why not?

JUSTINE: For prehistoric reptiles?

ELIZA: We’re agents of Paradox, for gods’ sake. For all we know we could be the ones who go back in time and start the human race. We could be the original Adam and Eve! Eve and Eve! Whatever!

JUSTINE: If that were true I think we’d have been informed.

ELIZA: I’d just quite like to ride on a dinosaur.

DOCTOR: Hello, welcome to my mind! Sorry for the mess.

DOCTOR: But it was a childish dream that made you a doctor! You dreamt you could hold back death. Isn't that true? Don't be sad, Grace. You'll do great things.

DOCTOR: I love humans. Always seeing patterns in things that aren’t there.
