DOCTOR: Okay. Name - the Doctor. Occupation - not a doctor. Current status - just passing by. Employer - myself. Address - that blue box over there. Now, if you don't mind, I just got snowmanned, and I would like to go home.

DOCTOR: It's funny, cos I wonder where the TARDIS goes at random. Maybe it lands on some outcrop by the sea. And there's a tribe and they worship it for 100 years. Then they grow up and try to burn it. Then they get wise. They preserve it. Then they build a city all around it, till the TARDIS is just a tiny little dot, surrounded by skyscrapers and monorails. Time passes and the city falls. It all gets swept away. And there's the TARDIS… still on its outcrop… by the sea. She's the only thing I've got left.

DOCTOR: Oh, the blossomiest blossom. That's the only sad thing. I want to know what happens next. Right, then. Doctor Whoever-I'm-about-to-be. Tag, you're it.

ELEVENTH DOCTOR: Know and time-travelling murderers with a passion for the convoluted?

TWELFTH DOCTOR: About two off the top of my head. But I’ve locked one in my basement and we’ve married the other.

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.

DOCTOR: Winning? Is that what you think it's about? I'm not trying to win. I'm not doing this because I want to beat someone, or because I hate someone, or because, because I want to blame someone. It's not because it's fun and God knows it's not because it's easy. It's not even because it works, because it hardly ever does. I do what I do, because it's right! Because it's decent! And above all, it's kind. It's just that. Just kind. If I run away today, good people will die. If I stand and fight, some of them might live. Maybe not many, maybe not for long. Hey, you know, maybe there's no point in any of this at all, but it's the best I can do, so I'm going to do it. And I will stand here doing it till it kills me. You're going to die too, some day. How will that be? Have you thought about it? What would you die for? Who I am is where I stand. Where I stand, is where I fall. Stand with me. These people are terrified. Maybe we can help, a little. Why not, just at the end, just be kind?

DOCTOR: Without hope. Without witness. Without reward.

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.

DOCTOR: They're not your rescuers. They're your replacements. The end point of capitalism. A bottom line where human life has no value at all. We're fighting an algorithm, a spreadsheet. Like every worker, everywhere, we're fighting the suits.

DOCTOR: My entire understanding of physical space has been transformed! Three-dimensional Euclidean geometry has been torn up, thrown in the air and snogged to death! My grasp of the universal constants of physical reality has been changed forever!

DOCTOR: Sorry. I've always wanted to see that done properly.

RIVER: Does sarcasm help?

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

DOCTOR: There's this emperor and he asks this shepherd's boy, how many seconds in eternity? And the shepherd's boy says there's this mountain of pure diamond. It takes an hour to climb it, and an hour to go around it! Every hundred years, a little bird comes and sharpens its beak on the diamond mountain. And when the entire mountain is chiselled away, the first second of eternity will have passed! You must think that's a hell of a long time. Personally, I think that's a hell of a bird.

BONNIE: It's not fair.

DOCTOR: Oh, it's not fair! Oh, I didn't realise that it was not fair! You know what? My TARDIS doesn't work properly and I don't have my own personal tailor.

BONNIE: The things don't equate.

DOCTOR: These things have happened, Zygella, they are facts. You just want cruelty to beget cruelty. You're not superior to people who were cruel to you, you're just a whole bunch of new cruel people. A whole bunch of new cruel people being cruel to some other people, who'll end up being cruel to you. The only way anyone can live in peace is if they're prepared to forgive. Why don't you break the cycle?

BONNIE: Why should we?

DOCTOR: What is it that you actually want?

BONNIE: War.

DOCTOR: Ah, ah right! And when this war is over, when you have a homeland free from humans, what do you think it's going to be like? Do you know? Have you thought about it? Have you given it any consideration? Because you're very close to getting what you want. What's it going to be like? Paint me a picture. Are you going to live in houses? Do you want people to go to work? Will there be holidays? Oh! Will there be music? Do you think people will be allowed to play violins? Who's going to make the violins? Well? Oh, you don't actually know, do you? Because, like every other tantrumming child in history, Bonnie, you don't actually know what you want. So, let me ask you a question about this brave new world of yours. When you've killed all the bad guys, and when it's all perfect and just and fair, when you have finally got it exactly the way you want it, what are you going to do with the people like you? The troublemakers. How are you going to protect your glorious revolution from the next one?

BONNIE: We'll win.

DOCTOR: Oh, will you? Well, maybe... maybe you will win! But nobody wins for long. The wheel just keeps turning. So, come on. Break the cycle.

BONNIE: Why are you still talking?

Because I want to get you to see, and I'm almost there!

BONNIE: You know what I see, Doctor? A box. A box with everything I need. A 50% chance.

KATE: For us, too.

DOCTOR: And we're off! Fingers on buzzers! Are you feeling lucky? Are you ready to play the game? Who's going to be quickest? Who's going to be the luckiest?

KATE: This is not a game!

DOCTOR: No, it's not a game, sweetheart, and I mean that most sincerely.

BONNIE: Why are you doing this?

KATE: Yes, I'd quite like to know that, too. You set this up -- why?

DOCTOR: Because it's not a game, Kate. This is a scale model of war. Every war ever fought, right there in front of you. Because it's always the same. When you fire that first shot, no matter how right you feel, you have no idea who's going to die! You don't know whose children are going to scream and burn! How many hearts will be broken! How many lives shattered! How much blood will spill until everybody does what they were always going to have to do from the very beginning -- sit down and talk! Listen to me. Listen, I just... I just want you to think. Do you know what thinking is? It's a fancy word for changing your mind.

BONNIE: I will not change my mind.

DOCTOR: Then you will die stupid. Alternatively, you could step away from that box, you can walk right out of that door and you could stand your revolution down.

BONNIE: No! I'm not stopping this, Doctor. I started it. I will not stop it. You think they'll let me go, after what I've done?

DOCTOR: You're all the same, you screaming kids. You know that? "Look at me, I'm unforgivable." Well, here's the unforeseeable. I forgive you... after all you've done. I forgive you.

BONNIE: You don't understand. You will never understand.

DOCTOR: I don't understand? Are you kidding? Me? Of course I understand. You mean, you call this a war? This funny little thing? This is not a war! I fought in a bigger war than you will ever know. I did worse things than you could ever imagine. And when I close my eyes... I hear more screams than anyone could ever be able to count! And do you know what you do with all that pain? Shall I tell you where you put it? You hold it tight... till it burns your hand, and you say this... No one else will ever have to live like this! No one else will have to feel this pain! Not on my watch!

DOCTOR: Sometimes the only choices you have are bad ones. But you still have to choose.

DOCTOR: We all change, when you think about it. We're all different people all through our lives. And that's okay, that's good, you've got to keep moving, so long as you remember all the people that you used to be. I will not forget one line of this. Not one day. I swear. I will always remember when the Doctor was me.

ELEVENTH DOCTOR: It's a timey-wimey thing.

WAR DOCTOR: Timey what? Timey-wimey?

TENTH DOCTOR: I've no idea where he picks that stuff up.

CLARA: Be a doctor. You told me the name you chose was a promise. What was the promise?

TENTH DOCTOR: Never cruel or cowardly.

WAR DOCTOR: Never give up, never give in.

DOCTOR: Charley, C'Rizz, Lucie, Tamsin, Molly. Friends, companions I've known, I salute you. And Cass, I apologise. Physician, heal thyself.

OHILA: We restored you to life, but it's a temporary measure. You have a little under four minutes.

DOCTOR: Four minutes? That's ages. What if I get bored? I need a television, couple of books, anyone for chess? Bring me knitting.

HOUSE: Fear me. I've killed hundreds of Time Lords.

DOCTOR: Fear me. I've killed all of them.

DOCTOR: We’re all stories, in the end. Just make it a good one, eh?

DOCTOR: People assume that time is a strict progression of cause to effect, but actually from a non-linear, non-subjective viewpoint, it's more like a big ball of wibbly-wobbly, timey-wimey... stuff.

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

DOCTOR: The Daleks have failed! Why don't you finish the job and make the Daleks extinct. Rid the Universe of your filth. Why don't you just die?

DALEK: You would make a good Dalek.
