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.

DOCTOR: Love, in all its forms, is the most powerful weapon we have. Because love is a form of hope. And like hope, love abides. In the face of everything.

DOCTOR: We’re all capable of the most incredible change. We can evolve while still staying true to who we are. We can honour who we’ve been and choose who we want to be next. Now’s your chance. How about it?

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.

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: 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?

RIVER: Does sarcasm help?

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

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: 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.

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

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

MASTER: The title you chose: Doctor. Now, it’s not just a man of healing. It means “teacher”. It means “tutor”. Whereas I am a Master. We both want to change the universe, to make it better, it’s only the scale of our ambition separates us.

DOCTOR: What are you saying? You’d like to have been a Doctor but you didn’t have the patients?

CLARA: I know it's scary and difficult, but do you love being the man making the impossible choice?

DOCTOR: Why would I?

CLARA: Because it's what you do, all day, every day.

DOCTOR: It's my life.

CLARA: Doesn't have to be. Is it like-

DOCTOR: Like what?

CLARA: An addiction?

DOCTOR: You can't really tell if something's an addiction till you try and give it up.

CLARA: And you never have.

DOCTOR: Let me know how it goes.

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.

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

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!

DOCTOR: I'm not running away. But this is one corner of one country in one continent on one planet that's a corner of a galaxy that's a corner of a universe that is forever growing and shrinking and creating and destroying and never remaining the same for a single millisecond. And there is so much, so much to see, Amy. Because it goes so fast. I'm not running away from things, I am running to them before they flare and fade forever. And it's all right. Our lives won't run the same. They can't. One day, soon maybe, you'll stop. I've known for a while.

DOCTOR: 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.

DOCTOR: Who's she?

SARDICK: Nobody important.

DOCTOR: Nobody important. Blimey, that's amazing. Do you know, in nine hundred years of time and space, I've never met anyone who wasn't important before.

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