DOCTOR: Come here. I've got you. Yeah? It's okay. I'm here.

DOCTOR: Wilfred Mott. Oh, now I feel better. Now nothing is wrong, nothing in the whole wide world! Hello, me old soldier!

WILF: I never thought I'd see you again after all these years. Oh, Doctor, that lovely face! It's like springtime.

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.

DONNA: Why did this face come back?

DOCTOR: I don't know.

DONNA: To say goodbye?

DOCTOR: We're binary.

DONNA: She's not, because the Doctor's…

DOCTOR: ..male…

DONNA: ..and female.

ROSE: And neither. And more.

DOCTOR: I really do remember, though. Every second with you. I'm so glad you're back, cos it killed me, Donna. It killed me, it killed me, it killed me.

ROSE: After all these years, I'm… finally me.

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

DOCTOR: Without hope. Without witness. Without reward.

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?

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

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

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?

I am the Doctor. I'm coming to find you, and I will never, ever stop.

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

QUELL: So, what are you a doctor of?

DOCTOR: Now, there's a question that's never asked often enough. Let's say intestinal parasites.

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: Imagine a thing that must never be seen. What would it do if you saw it?

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.
