DOCTOR: This has been an absolute joy.

"ROSE TYLER": Oh, hello!

DOCTOR: That’s our lives, Belinda. We travel in and out of the slipstreams of time. Beautiful things can be forgotten and gone. But they still happened, somewhere. I think one thing remains. I love you. And I love you, Pops. That will never change.

SCOOT: Polish Polish

NARVIN: I loathe small talk. I rarely engage in it It seems such a pointless waste of effort.

SUSAN: Oh, pet. Anything to help. I don't mind. I'll make the tea.

IBRAHIM: Did you make this tea?

SUSAN: I did, yes.

IBRAHIM: Don't make the tea.

RUBY: Who are you?

DOCTOR: I'm the Doctor.

FLOOD: Busy man, sweetheart. You and your box of tricks. You look like you've lost a pound and found a sixpence. What's wrong?

DOCTOR: Just wondering. Maybe I'm the bad luck.

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: Was it me, or was Isaac Newton hot?

DOCTOR: He was, wasn't he? He was so hot. Oh! Is that who I am now?

DONNA: Well, it was never that far from the surface, mate. I always thought…

DONNA: Have you got the controls set to "famous", or what?

Not-Thing: My arms are too long.

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: I know these teeth. What? What? What?!

TENTH DOCTOR: What? What?

SIXTH DOCTOR: What are you afraid will happen if you pause for breath?

TENTH DOCTOR: That there won't be another.

DOCTOR: It’s not about losing hope. It’s about never forgetting that hope's always there, even when you can’t see it.

DOCTOR: You don’t need me telling you your family isn’t always the one you were born in. Usually it is, and that’s great, that’s fantastic, but it’s not always like that, and that’s ok. And if you do find people who love you - hold on tight.

YASMIN: Make a wish and skim it.

DOCTOR: I wish...

YASMIN: You can't say your wish out loud!

DOCTOR: You can where I'm from. I wish... I wish this would go on forever.

DOCTOR: Two hearts. One happy, one sad.

RANI: You know what I think? I think it's not over, because I don't think she's dead. I really don't. That's not just me being mad, cos I honestly think in my heart and soul that he came back for her. Right at the end, the Doctor came back for his Sarah Jane, and he said, shall we go? Out into the stars? One last trip? And she said, oh yes please. And I think they're out there now, Sarah Jane and the Doctor in the TARDIS, travelling through space and time forever, in a story that never ends.

DOCTOR: None of us know for sure what's out there. That's why we keep looking. Keep your faith. Travel hopefully. The universe'll surprise you... constantly.

The lives of the Doctor run together.

I see a hero. I see a changeling. I see a warrior. I see a god. I see faces change, and hearts break. The pages tear as futures writhe and on some there is fear and on others hope, and on a thousand more I see a world of green and blue and I know that’s where he’s headed, where he’ll go a million times, where he’ll go as long as they’ll have him and sometimes a little bit more.

FIRST DOCTOR: There is good and there is evil. I left Gallifrey to answer a question of my own. By any analysis, evil should always win. Good is not a practical survival strategy - it requires loyalty, self-sacrifice and love. And so, why does good prevail? What keeps the balance between good and evil in this appalling universe? Is there some kind of logic? Some mysterious force?

BILL: Perhaps it's just... a bloke.

FIRST DOCTOR: A... bloke?

BILL: Yeah! Perhaps it's just some bloke, wandering around, putting everything right when it goes wrong.

FIRST DOCTOR: Well, that would be a nice story, wouldn't it?

BILL: That would be the best.

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.
