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: 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: Without hope. Without witness. Without reward.

DOCTOR: Who I am is where I stand. Where I stand is where I fall.

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: Human progress isn't measured by industry, it's measured by the value you place on a life. An unimportant life. A life without privilege. The boy who died on the river, that boy's value is your value. That's what defines an age. That's what defines a species.

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: So, assuming tonight is all we have left.

DOCTOR: I didn't say that.

RIVER: How long is a night on Darillium?

DOCTOR: Twenty four years.

RIVER: I hate you.

DOCTOR: No, you don't.

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?

DOCTOR: Nothing’s sad until it’s over, and then everything is.

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.

DOCTOR: If you think because she is dead I am weak, then you understand very little. If you were any part of killing her, and you're not afraid, then you understand nothing at all. So, for your own sake, understand this. I am the Doctor. I'm coming to find you, and I will never, ever stop.

DOCTOR: I can't! Why is it always me? Why is it never anybody else's turn? Can't I just lose? Just this once?

DOCTOR: As you come into this world, something else is also born. You begin your life, and it begins a journey towards you. It moves slowly, but it never stops. Wherever you go, whatever path you take, it will follow. Never faster, never slower, always coming. You will run. It will walk. You will rest. It will not. One day, you will linger in the same place too long. You will sit too still or sleep too deep, and when, too late, you rise to go, you will notice a second shadow next to yours. Your life will then be over.

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: Do you know what thinking is? It’s just a fancy word for changing your mind.

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

DOCTOR: Let me tell you about scared. Your heart is beating so hard, I can feel it through your hands. There's so much blood and oxygen pumping through your brain, it's like rocket fuel. Right now, you could run faster and you could fight harder, you could jump higher than ever in your life. And you are so alert, it's like you can slow down time. What's wrong with scared? Scared is a superpower. It's your superpower. There is danger in this room and guess what? It's you.

DOCTOR: He asked you a question. Will you help me?

CLARA: You shouldn't have been listening.

DOCTOR: I wasn't. I didn't need to. That was me talking. You can't see me, can you? You look at me, and you can't see me. Have you any idea what that's like? I'm not on the phone, I'm right here, standing in front of you. Please, just, just see me.

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.

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.

DOCTOR: I walked away from the last Great Time War. I marked the passing of the Time Lords.

I saw the birth of the universe and I watched as time ran out, moment by moment, until nothing remained.

No time. No space. Just me.

I walked in universes where the laws of physics were devised by the mind of a mad man.

I've watched universes freeze and creations burn. I've seen things you wouldn't believe. I have lost things you will never understand.

And I know things. Secrets that must never be told. Knowledge that must never be spoken. Knowledge that will make parasite gods blaze.

So come on, then. Take it! Take it all, baby! Have it! You have it all!
