TEGAN: I can't go back there Doctor, you can't let me go back there.

DOCTOR: I won't.

ADRIC: The Doctor can find a way out of this Tegan, you know that, he'll never let any of us down.

TEGAN: This is you all over Doctor, you're always thinking about the adventure, you never stop to look after the people you're supposed to care about!

DOCTOR: That's not fair.

NYSSA: The Doctor was trying to protect you Tegan.

TEGAN: Only as far as it suited his own interests.

DOCTOR: So, what are you going to do while I pop over and get her?

TEGAN: You must be kidding, you're not going in there without me.

DOCTOR: I don't want to argue with you Tegan.

TEGAN: Then don't. You can't leave me behind, we're in this together.

DOCTOR: You realise the danger?

TEGAN: Of course I do! And I get why you're worried, okay? But what happened to Adric, isn't going to happen to me.

DOCTOR: You don't know that.

TEGAN: I do know that I'm not staying here while you and Nyssa are in danger. So unless you plan on locking me up-

DOCTOR: Alright, alright.

DOCTOR: You know Tegan, sometimes I wonder how well I'd get along without you.

TEGAN: Thank you.

DOCTOR: Probably quite alright, all things considered. Now, a fresh cup of tea would be terribly useful.

TEGAN: Yeah? Well, you know where the kitchen is.

TEGAN: You… helped me? You could’ve escaped!

ADRIC: You talk of family; we’re family

DOCTOR: Murder isn't just a puzzle, you know, it's about the people too. The lives that are irrevocably changed.

TEGAN: And that's why you're nervous to investigate?

DOCTOR: I'm not nervous. Saddened. Dismayed. When I was a different me I was hardened to that, in this incarnation I think I feel it more.

DOCTOR: What the hell are you doing?!

RUBY: I'm... just... There's...

DOCTOR: But what did you do that for? Who sees a ladder and just pops on? A ladder in the sky and you thought, "Yeah, I'll give that a go, babes"?

RUBY: They've got the baby!

DOCTOR: Health and safety. Gin and tonic division.

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: 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: It's nice to spend some time together, just the two us, don't you think?

ADRIC: I suppose so... Though, why you'd want to spend any time with me after what happened with the TSS unit, I don't know. You were so angry with me.

DOCTOR: Um, I'm sorry. I know I can be a little hard on you at times, Adric, but I see potential in you, that's all. I would hate for it to go to waste.

ADRIC: Why would it go to waste?

DOCTOR: Because sometimes you're impulsive, and you act before you've fully thought the consequences of things through.

ADRIC: I'm not stupid!

DOCTOR: No! No, you're not.

ADRIC: Then why do you treat me like a child?

DOCTOR: I... I'm afraid of losing you.

ADRIC: You're not going to lose me. I mean, where would I go? You're all I have; you, Tegan and Nyssa.

DOCTOR: I know.

ADRIC: I'm capable of so much more than you think I am. If you'd just give me a chance to prove myself.

DOCTOR: I know, you're extremely capable. One day, you're going to do something great, something very important

ADRIC: Doctor, are you sure you're feeling alright?

DOCTOR: No. No, not really.

DOCTOR: How would you feel about destroying this place?

SARAH: I mean, I'd have to talk to my insurance providers.

DOCTOR: I don't think you'll be covered for an Act of Dalek.

DOCTOR: What did you do?

NICK: It was a lot of strategic analysis, weapons assessment and battle-ready thinking.

DOCTOR: Did you duck?

NICK: Yeah.

DOCTOR: Oh, Jeff. You bad, bad man. Yaz, this is the sort of stuff about which you would ask yourself, if I set fire to this, will it have explosive and potentially devastating consequences? And the answer is yes.

DOCTOR: Because something seems impossible. We try, it doesn't work, we try again. We learn, we improve, we fail again, but better, we make friends, we learn to trust, we help each other. We get it wrong again. We improve together, then ultimately succeed. Because this is what being alive is. And it's better than the alternative. So come on, you brilliant humans. We go again and we win. Deal?

DOCTOR: What about you? Any plans? Seeing friends?

DALEK: Daleks do not have friends.

DOCTOR: Yeah, well, you've only got yourselves to blame for that.

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?

JUDGE: The court will now consider your sentence: either deportation to Australia-

ADRIC: Oh, Tegan’s from there, I’m not sure I’d like that

JUDGE: -or death!

ADRIC: … Australia sounds nice

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.

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?

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: 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.
