VALARIE: As my mum told me once - don't put anything off until tomorrow... Except giving up.

DOCTOR: Oh! Pssh! They are not time travellers. Excuse me. Time travellers are great. Like the best. Like, wow. This lot just bimble.

DOCTOR: The funny thing is, I fought all those battles for all those years, and now I know what for. This. I've never been so happy in my life.

15th DOCTOR: Mel, what do you think?

MEL: I think you're beautiful.

14th DOCTOR: Still beautiful?

MEL: Yeah.

DONNA: But you keep on going. And that's the adventure. The one adventure you've never had. Because I've… I've worked out what happened. You changed your face, and then you found me. Do you know why?

14th DOCTOR: No.

DONNA: To come home.

15th DOCTOR: Ah! It's more than that. Our whole lifetime. That Doctor that first met the Toymaker never, ever stopped. Put on trial, exiled, Key to Time, all the devastation of Logopolis.

14th DOCTOR: Adric.

15th DOCTOR: Adric. River Song. All the people we lost. Sarah Jane has gone. Can you believe that for a second?

14th DOCTOR: I loved her.

15th DOCTOR: I loved her. And Rose. But the Time War, Pandorica, Mavic Chen. We fought the Gods of Ragnarok, and we didn't stop for a second… ..to say, what the hell?

14th DOCTOR: But you're fine.

15th DOCTOR: I'm fine because you fixed yourself. We're Time Lords. We're doing rehab out of order.

15th DOCTOR: We won the game. You get a prize, honey, and here is mine!

15th DOCTOR: Look after him, you know? Now, you two, if you don't mind, there is a great big universe out there calling, and I've got to get going. So off you pop, old man.

14th DOCTOR: Oh. You're the old man. You're older than me.

DONNA: Actually, that is true. He's younger because you came after him. So you're the older Doctor.

15th DOCTOR: Okay, kid. I love you. Get out!

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: You okay?

DOCTOR: I will be.

DONNA: When?

DOCTOR: A million years.

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 destroyed half the universe because of me. We stand here now on the edge of creation, a creation which I devastated. So, yes, I keep running. Of course I do. How am I supposed to look back on that?

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: Two hearts. One happy, one sad.

FUGITIVE DOCTOR: Let me take it from the top. Hello, I’m The Doctor.

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?

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: 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: You look, er, amazing.

RIVER: Doctor, you have no idea whether I look amazing or not.

DOCTOR: Well, you've moved your hair about, haven't you?

RIVER: Well done. It's very sweet of you to try.

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.
