ANNALORE: Heroes don't need villains in order to be heroes.

DOCTOR: He'd have loved you.

ANNALORE: Who?

DOCTOR: The Doctor. An aggressor turned ally? An invasion foiled, all due to reason and debate. Not a single shot fired! No one dead! No one even injured! Congratulations. He's be proud of every single one of you.

ANNALORE: Thank you.

DOCTOR: Pity he's dead.

ALISTAIR DONOVAN: Say something else.

WAR DOCTOR: There's nothing I can say.

ALISTAIR DONOVAN: Do something then!

WAR DOCTOR: Nothing to be done.

ALISTAIR DONOVAN: You're the Doctor!

WAR DOCTOR: No. I'm just what's left.

LUX: I'm a two-dimensional character, you can't expect a backstory!

SCOOT: Polish Polish

CHRIS: The overrides are biometrically linked to me.

DOCTOR: So I’d need a sample of your DNA to trip the lock. Right! You know what you need to do.

CHRIS: Oh, all right, fine. I’ll kiss you.

(Mwah! Chris kisses the Doctor.)

DOCTOR: Oh. No, I just meant a follicle of your hair.

CHRIS: Oh. Really?

DOCTOR: But don’t worry about it.

CHRIS: Oh, I’m so embarrassed.

DOCTOR: There should be enough on my lips, um—oh, actually I probably need a bit extra. Hang on.

(Mmmmwah! The Doctor kisses Chris back.)

DOCTOR: I mean, basically the code came from nowhere, but then so did the universe, and no-one complains about that.

DOCTOR: Ugh! Do you see? This is why nobody likes you! You have to be mysterious all the time. That's why everyone leaves you. That is why you are always alone.

DOCTOR: Do you know how lonely you are? You live in a great, big, giant spaceship and there aren't any chairs! And you haven't even noticed because nobody ever comes round!

PARS: That’s what Time Lords have always done, Bevvakk. Build a great many doors. Then lock them all, and hidden the keys.

They always found one another, didn't they? Romana, and Narvin, and Leela; always together in some combination. An enclave of familiarity against the vastness of time.

TEGAN: This is you all over Doctor, you're always thinking about the adventure, you never stop to look after the people you're supposed to care about!

DOCTOR: That's not fair.

NYSSA: The Doctor was trying to protect you Tegan.

TEGAN: Only as far as it suited his own interests.

EMILY BARNFATHER: Who are you Doctor?

DOCTOR: I am me.

DOCTOR: We’re not lost, Charley. Think of it more as we’ve “gone on holiday by mistake”.

CHARLEY: Doctor, that’s life with you all over!

DOCTOR: What can I say? I’m the original accidental tourist.

DOCTOR: We've gone on holiday by mistake!

RUATH: I'm so glad you remember me Doctor.

DOCTOR: Ruath! How could I possibly forget you?

RUATH: 700 years is an awfully long time. I see you're on your fifth body already, very careless of you.

DOCTOR: The universe is rather more dangerous than Gallifrey.

DOCTOR: You know Tegan, sometimes I wonder how well I'd get along without you.

TEGAN: Thank you.

DOCTOR: Probably quite alright, all things considered. Now, a fresh cup of tea would be terribly useful.

TEGAN: Yeah? Well, you know where the kitchen is.

CYBERLEADER: You are not from this world. You are a Timelord.

DOCTOR: Oh, is that why my body keeps changing? I just thought it was vindictive puberty.

HAYDEN: It is a necessary evil.

DOCTOR: Oh I've met evils you wouldn't believe, gods and devils, warewolves and vampires, every monster every child's ever imagined creeping out from under the bed and you know what? They're all real. But a necessary evil - that's the only one that's a fiction.

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…

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?

DONNA: I was thinking… And let me finish, okay? I know I sound daft, but… I wonder how long they'll wait, Rose and Shaun and my mother. Standing there in that alley… waiting for the TARDIS to come back. What if we never do? And then time will pass. Rose will grow up, she'll have a life. She might go back to that alley once a year for old times' sake, but she'll move on. Not Shaun, though. He'll keep going back every single day. He's nice, you know. He's lovely. I hope you get to know him.

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.
