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: Without hope. Without witness. Without reward.

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: It's my back.

RIVER: Your back?

DOCTOR: Yeah, my back's playing up. It simply refuses to carry the weight of an entirely pointless stratum of society who contribute nothing of worth to the world and crush the hopes and dreams of working people.

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: I've finally run out of corridor. There's a life summed up.

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.

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.

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: London...what a dump.

DOCTOR: You betrayed me. Betrayed my trust, you betrayed our friendship, you betrayed everything that I've ever stood for. You let me down!

CLARA: Then why are you helping me?

DOCTOR: Why? Do you think I care for you so little that betraying me would make a difference?

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: 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.

WAR DOCTOR: Great men are forged in fire. It is the privilege of lesser men to light the flame, whatever the cost.

(River's image goes to hit the Doctor, and he catches her arm in his hand.)

RIVER: How are you even doing that? I'm not really here.

DOCTOR: You are always here to me. And I always listen, and I can always see you.

DOCTOR: There are laws of time. Once upon a time there were people in charge of those laws, but they died. They all died. Do you know who that leaves? Me! It's taken me all these years to realize that the laws of time are mine and they will obey me!
