DOCTOR: She just dropped some coffee into the console.

DONNA: But don't worry, he's got a time machine, which means he can blame me for all eternity.

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

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: Allons - as idiots say - y.

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.

Not-Thing: My arms are too long.

Not-Doctor: The notion of shape is strange.

Not-Donna: It limits. It is limiting.

Not-Donna: We came from nothing.

Not-Doctor: We are not-things.

Not-Donna: But you, you’re not nothing.

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've got to say, this is the biggest nightmare of my life. But… I look quite good.

NOT-DONNA: I can't argue.

DOCTOR: Oh, I keep thinking, I wish I hadn't done that thing with the salt.

DONNA: What, the bad luck thing? But that was just a lie.

DOCTOR: Normally, except… I invoked a superstition at the edge of the universe, where the walls are thin and all things are possible. I've just got this feeling.

DONNA: What?

DOCTOR: A feeling of something… which is gone. Fine. Good. Onwards.

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.
