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

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: You're gonna have to trust me on this, Yaz. When have I ever let you down before?

DOCTOR: I won't disappear again.

YASMIN: Yeah, you will. One day, you will.

HARKNESS: How many people in the universe get to meet the Doctor, let alone travel with her? We're the lucky ones, Yaz. Enjoy the journey while you're on it. Cos the joy... is worth the pain.

DOCTOR: Two hearts. One happy, one sad.

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.

MASTER: Is the future going to be all girl?

DOCTOR: We can only hope.

FIRST DOCTOR: The Doctor? No, I don't think so! No, dear me, no! You may be a Doctor, but I am the Doctor. The original, you might say!

DOCTOR: Without hope. Without witness. Without reward.

DOCTOR: Winning? Is that what you think it's about? I'm not trying to win. I'm not doing this because I want to beat someone, or because I hate someone, or because, because I want to blame someone. It's not because it's fun and God knows it's not because it's easy. It's not even because it works, because it hardly ever does. I do what I do, because it's right! Because it's decent! And above all, it's kind. It's just that. Just kind. If I run away today, good people will die. If I stand and fight, some of them might live. Maybe not many, maybe not for long. Hey, you know, maybe there's no point in any of this at all, but it's the best I can do, so I'm going to do it. And I will stand here doing it till it kills me. You're going to die too, some day. How will that be? Have you thought about it? What would you die for? Who I am is where I stand. Where I stand, is where I fall. Stand with me. These people are terrified. Maybe we can help, a little. Why not, just at the end, just be kind?

MISSY: Exciting, isn't it? Watching the Cybermen getting started.

DOCTOR: They always get started. They happen everywhere there's people. Mondas, Telos, Earth, Planet 14, Marinus. Like sewage and smartphones and Donald Trump, some things are just inevitable.

BILL: You said. I remember, you said you could fix this. That you could get me back. Did you say that?

DOCTOR: I did say that, yes.

BILL: Were you lying?

DOCTOR: No.

BILL: Were you right?

DOCTOR: No.

DOCTOR: Who I am is where I stand. Where I stand is where I fall.

DOCTOR: We had a pact, me and him. Every star in the universe, we were going to see them all. But he was too busy burning them. I don't think she ever saw anything.

BILL: So, the Time Lords, bit flexible on the whole man-woman thing, then, yeah?

DOCTOR: We're the most civilised civilisation in the universe. We're billions of years beyond your petty human obsession with gender and its associated stereotypes.

BILL: But you still call yourselves Time Lords?

DOCTOR: Yeah. Shut up.

DOCTOR: It's as if his bones have disintegrated.

NARDOLE: Ooo. What could do that?

DOCTOR: A complete and total absence of any kind of sunlight.

NARDOLE: Death by Scotland.

BILL: Maybe someone's been messing around with time. Like in The Terminator.

DOCTOR: The Terminator?

BILL: It's a movie. You haven't seen it?

DOCTOR: I'm a very busy man.

(He is scanning ahead with the sonic screwdriver.)

BILL: You'd like it. It's got killer robots.

DOCTOR: Ooo, I'll put it on me list.

DOCTOR: Even if that was the truth, the fact that you're suggesting it shows there's been no change, no hope, no point. We don't sacrifice people. It's wrong, because it's easy.

MISSY: You know, back in the day, I'd burn an entire city to the ground just to see the pretty shapes the smoke made. I'm sorry your plus one doesn't get a happy ending, but, like it or not, I just saved this world because I want to change.

MISSY [OC]: Your version of good is not absolute. It's vain, arrogant and sentimental. If you're waiting for me to become all that, I'm going to be here for a long time yet.

MISSY: I am your friend.

DOCTOR: Makes no difference.

MISSY: I know it doesn't. I know I'm going to die. I have to say it, the truth. Without hope. Without witness. Without reward. I am your friend.

BILL: Doctor, you okay?

DOCTOR: Bill, I've got no TARDIS, no sonic, about ten minutes of oxygen left, and now I'm blind. Can you imagine how unbearable I'm going to be when I pull this off?

DOCTOR: They're not your rescuers. They're your replacements. The end point of capitalism. A bottom line where human life has no value at all. We're fighting an algorithm, a spreadsheet. Like every worker, everywhere, we're fighting the suits.

DOCTOR: Oh, look, Bill, it's Nardole. What a lovely surprise. I thought I sent you to Birmingham for a packet of crisps. 


NARDOLE: Yeah, I saw through your cunning ruse. 


DOCTOR: Yes, well, if you will go thinking for yourself. What do you want? 


NARDOLE: I was given strict instructions to keep you at the university. 


DOCTOR: Who by?


NARDOLE: You.


DOCTOR: Well, you're not doing a very good job, are you? I'll overlook it this once. 


NARDOLE: Do you know what this is? 


DOCTOR: If it's not crisps, you're sacked.

DOCTOR: Human progress isn't measured by industry, it's measured by the value you place on a life. An unimportant life. A life without privilege. The boy who died on the river, that boy's value is your value. That's what defines an age. That's what defines a species.
