OHILA: We restored you to life, but it's a temporary measure. You have a little under four minutes.

DOCTOR: Four minutes? That's ages. What if I get bored? I need a television, couple of books, anyone for chess? Bring me knitting.

“Charley, C'Rizz, Lucie, Tamsin, Molly. Friends, companions I've known, I salute you. And Cass, I apologise. Physician, heal thyself.”

DOCTOR: I just want to say, you know, you have never been very reliable.

IDRIS: And you have?

DOCTOR: You didn't always take me where I wanted to go.

IDRIS: No, but I always took you where you needed to go.

“I wanted to see the universe, so I stole a Time Lord and I ran away. And you were the only one mad enough.”

“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.”

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: You let one of them go, but that's nothing new. Every now and then, a little victim's spared because she smiled, because he's got freckles, because they begged. And that's how you live with yourself. That's how you slaughter millions. Because once in a while, on a whim, if the wind's in the right direction, you happen to be kind.

MARGARET: Only a killer would know that. Is that right? From what I've seen, your funny little happy go lucky little life leaves devastation in its wake. Always moving on because you dare not look back. Playing with so many peoples lives, you might as well be a god. And you're right, Doctor. You're absolutely right. Sometimes you let one go. Let me go.

I.M. FOREMAN: You’ve never been a woman, have you?

DOCTOR: I’m not sure I’ve ever even been a man.

EVELYN: Oh no. You are going to sing.

DOCTOR: Well, yes, I am.

DOCTOR: When does all this stop for you? The games, the betrayals, the killing?

MASTER: Why would it stop? I mean, how else would I get your attention?

“There's this emperor and he asks this shepherd's boy, how many seconds in eternity? And the shepherd's boy says there's this mountain of pure diamond. It takes an hour to climb it, and an hour to go around it! Every hundred years, a little bird comes and sharpens its beak on the diamond mountain. And when the entire mountain is chiselled away, the first second of eternity will have passed! You must think that's a hell of a long time. Personally, I think that's a hell of a bird.”

“What do you want me to be? Someone who knows exactly what he’s doing and has it all under control, or just some fellow who makes it up as he goes along, and still makes it happen? Which do you want it to be? Magic tricks, or magic?”

“[Shouting] All hail Frobisher! All hail the big talking bird!”

YANA: Time and time and time again. Always running out on me.

MARTHA: Can I have a look at that?

YANA: Oh, it's only an old relic. Like me.

MARTHA: Where did you get it?

YANA: Hmm? I was found with it.

MARTHA: What do you mean?

YANA: An orphan in the storm. I was a naked child found on the coast of the Silver Devastation. Abandoned, with only this.

MARTHA: Have you opened it?

YANA: Why would I? It's broken.

MARTHA: How do you know it's broken if you've never opened it?

YANA: It's stuck. It's old. It's not meant to be. I don't know.
