DOCTOR: Don't be sorry. Don't be sorry at all. Your life… is out there now. I've shown you monsters and planets, and legends… but this… Honey, your adventure is just beginning.

DOCTOR: We fought a monster. And now… I must become a monster.

RUBY: Why does a land mine have lights on it?

DOCTOR: Oh, capitalism.

RUBY: Excuse me?

DOCTOR: Flashy lights play well in a showroom. Modern warfare. Death by salesman.

DOCTOR: If it goes wrong, you will be caught in the blast.

RUBY: Well, let's get it right, then.

DOCTOR: Ruby, I forbid this.

RUBY: Yeah, good luck with that.

SPLICE: Silly. He's not gone. He's just dead. He's not gone.

DOCTOR: That is right. That is exactly right. You keep the faith, Splice.

MUNDY: I thought you didn't like faith much, Doctor.

DOCTOR: Just because I don't like it doesn't mean I don't need it, Mundy.

DOCTOR: I'm a much bigger bang than you bargained for. I'm a lot more explosive than I look, and honey... I know how I look. Put a quantum chain reaction through me and I will shatter this silly little battlefield of yours into dust. All of it, in a heartbeat, into dust.

DOCTOR: I went down to the beach and there she stood, dark and tall at the edge of the wood. "The sky's too big, I'm scared," I cried. She replied, "Young man, don't you know there's more to life than the moon and the President's wife?"

DOCTOR: Yeah, two minutes, no lingering. Plenty more universe to see and, quite frankly, your lifespan sucks.

RUBY: Where are we?

DOCTOR: In the middle of a war.

RUBY: Oh. I was kind of hoping for a beach.

DOCTOR: Ah. What do you think this is?

RUBY: It's not a beach.

DOCTOR: Give it time. Everywhere's a beach eventually.

DOCTOR: Most armies would notice that they were fighting smoke and shadows, but not this lot, Ruby. You know why? Cos they have faith.

MUNDY: Shut up.

DOCTOR: Faith. The magic word that keeps you never having to think for yourself. Just surrender, Mundy. Just stop, and it's all over.

MUNDY: Prove it.

DOCTOR: What, seriously? Now you need proof, faith gyal?

DOCTOR: We're all dead eventually. There's hardly any time that we're not dead. Which is a good thing, too. We've got to keep the pace up, otherwise nothing would get done. Dying defines us. Snow isn't snow until it falls.

RUBY: Snow...?

DOCTOR: Yeah, snow. We all melt away in the end, but something stays. Maybe the best part.

DOCTOR: Great name, Mundy Flynn. You should marry Ruby. Then you'd be Mundy Sunday. Go on, get married, I'd laugh every day.

MAESTRO: Music, Maestro, please!

DOCTOR: Okay. Name - the Doctor. Occupation - not a doctor. Current status - just passing by. Employer - myself. Address - that blue box over there. Now, if you don't mind, I just got snowmanned, and I would like to go home.

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.

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: Right, fam, I thought we could try the Meringue Galaxy. It's not a place, it's a restaurant where every course is meringue. And the furniture. Plus the waiters!

RYAN: Yeah. Me mates need me. And I know this sounds stupid, but... I feel like my planet needs me. You've got to fight for it, right? Look, Doctor, before... before I met you, I didn't know what I wanted to do with me life. And... and now... And now, I know.

DOCTOR: Ten months. I made it back too late. Missed my time with you.

RYAN: So, are we hugging, or...?

DOCTOR: Two hearts. One happy, one sad.

DOCTOR: Love, in all its forms, is the most powerful weapon we have. Because love is a form of hope. And like hope, love abides. In the face of everything.

DOCTOR: We’re all capable of the most incredible change. We can evolve while still staying true to who we are. We can honour who we’ve been and choose who we want to be next. Now’s your chance. How about it?

ARCHIBALD HAMISH LETHBRIDGE-STEWART: World War One?

DOCTOR: Judging by the uniform, yes.

ARCHIBALD HAMISH LETHBRIDGE-STEWART: Yes, but... What do you mean "one"?

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.

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.
