ROMANA: Kill every last person and Unity becomes just another dead rock. Like all the other dead rocks you've left in your wake.

DALEK: Negative. Unity is more than other worlds.

ROMANA: You mean it's your fuel source. And who's going to mine that fuel? There's a war on. You don't have Daleks to spare.

DALEK: We will spare enough lives to keep the mines in operation.

ROMANA: And who will shuttle the miners back and forth to the mines? Who will cook their meals? Who will look after their children? Who will sweep the streets, and wash the laundry, and fix the plumbing? Who will live?

DALEK: That is not our concern.

ROMANA: No, I thought not, somehow.

DALEK: Provide us with the location of your associates.

ROMANA: We've been here before though, and I will never betray those I love. Not ever. So what are you going to do about it?

DALEK: Exterminate.

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?

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: 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.

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: 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.

MISS QUILL: That's the size of a kitten.

BALLON: Are kittens dangerous?

MISS QUILL: Only if you insult their worshippers online.

(Miss Quill reading The Hunger Games)

MISS QUILL: Did this really happen?

(Armitage enters.)

QUILL: Leave us! We are decorating.

(Armitage leaves.)

ROMANA: So it was you following me. You were here the whole time.

LEELA: I thought you might need some help.

ROMANA: But I said- I told you, I had to do this alone.

LEELA: And I said I thought you were being foolish. And I meant it.

LEELA: It felt like punishment. Those moments when I thought you had abandoned me like… exile.

ROMANA: I didn’t abandon you. I thought I was saving you.

NARVIN: I thought we’d lost you.

ROMANA: No chance of that, Narvin. I’m here to stay.

ROMANA: Madame President. With all due respect, if I took a week or even a day off for every friend I’ve lost, I wouldn’t get a great deal done.

ROMANA: But this isn’t the end. There’s still a place where we go on. I promise you. This will not be the end. And I’m so sorry that I abandoned you. Forgive me.

LEELA: There is nothing to forgive.

LEELA: I often wonder how my life would have turned out if he had not come.

ROMANA: Who?

LEELA: The Doctor, of course. All of time and space to voyage but he came to my world at that exact moment. If he had come to us a century before my time or after it. Perhaps he would have taken someone else.

ROMANA: But he didn’t. He took you.

LEELA: But if he had not. Perhaps I would have become old. One of the elders of my tribe. Or… or perhaps I would have remained banished and died alone in some forgotten cave. Anyways, I would have passed long ago and I would have seen so little. Experienced so little.

DOCTOR: We’ll have the door open in a jiffy.

LIV: Except we still don’t know what’s out there.

HELEN: Please be careful!

DOCTOR: Are you scaredy cats?

HELEN: No

LIV: Just sensible

DOCTOR: Oh come on, we could sit here all day being sensible, we’d still be here next week, filling out risk assessment forms. And how boring would that be?

DOCTOR: It's my back.

RIVER: Your back?

DOCTOR: Yeah, my back's playing up. It simply refuses to carry the weight of an entirely pointless stratum of society who contribute nothing of worth to the world and crush the hopes and dreams of working people.

DOCTOR: I'm a doctor. But probably not the one you're expecting.

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.

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

TREY: I’m worried, that’s all. Not that I have a problem with aliens, oh dear me no. My best friend is one after all.

LEELA: She is quicksilver. I prefer steel.

ROMANA: Goodbye, Gallifrey. I’d like to think you’d miss me but I don’t think you’ll even notice I’m gone. And who knows? One day. I may come back. Yes, one day.
