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

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?

DOCTOR: Without hope. Without witness. Without reward.

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.

LIV: I’ll stay, you know. As long as you need me

DOCTOR: We all need someone. That’s what hope is. Other people.

CLARA: Be a doctor. You told me the name you chose was a promise. What was the promise?

TENTH DOCTOR: Never cruel or cowardly.

WAR DOCTOR: Never give up, never give in.

LUCIE: (transmitter) ... Don't know. Maybe I'll just give you this Interocitor gizmo thing and you can play back this message, and then you'll look all pompous and say something like, "well, what if I don't want you to travel with me any more, Lucie Miller?" And I'll give you a kick in the shins and you'll say, "Ow, that hurt," and I'll say "I'll take that as a yes then, shall I?" (Laugh.) Yeah. Maybe that's how it'll go. That's what I'd like, Doctor. That's what I really like.

(Rewinding.)

LUCIE: (transmitter) ... play back this message, and then you'll look all pompous and say something like, "well, what if I don't want you to travel with me anymore, Lucie Miller?" And I'll...

(Rewinding.)

LUCIE: (transmitter) ... then you'll look all pompous and say something like...

THE DOCTOR: Well, what if I don't want you to travel with me any more, Lucie Miller?

(Fast forward.)

LUCIE: (transmitter) I'll give you a kick in the shins and you'll say...

THE DOCTOR: Ow, that hurt.

(Fast forward.)

LUCIE: (transmitter) ... and I'll say "I'll take that as a yes then, shall I?" (Laugh.) Yeah. Maybe that's how it'll go. That's what I'd like, Doctor. That's what I really like.

THE DOCTOR: It's a distress call, and it's been waiting for some time. The TARDIS must have known I was busy.

LUCIE: (transmitter) Hello? Doctor?

DAPHNE: That's ... me, isn't it?

LUCIE: (transmitter) It's me. Lucie.

THE DOCTOR: With all due respect...

LUCIE: (transmitter) Lucie Miller.

THE DOCTOR: That is the real thing.

LUCIE: (transmitter) Don't know when, where you'll be receiving this. Maybe you've forgotten all about me, again. But you left this daft gizmo thing behind, so that I could call you if I needed help. Well, I do. We all do. The whole bloomin' human race is in real trouble.

DOCTOR: Is this London?

TODD HULBERT: Yes. I used to be based in Ipswich. But when somebody’s come half way across the galaxy for a business lunch, they don’t want to have it in Ipswich.

DOCTOR: Understandable.

THE DOCTOR: Sounds like they put you on a witness protection scheme.

LUCIE: Oh yeah.

THE DOCTOR: And dumped you on me. Oh, I should have known. Who else could have shot you right into the heart of my TARDIS? Who else could have erected a shield in the vortex itself to keep me from taking you home? (Louder) And who else would presume to meddle in my life like this?

LUCIE: Yeah, they said you'd get a proper nark on about it. I remember that.

THE DOCTOR: Well, I'm not going to stand for it. Take her away. Come on, if you can ... if you can go to all the trouble of breaking down the TARDIS's defences to dump her on me, you can lift her off this godforsaken planet with no trouble at all. Come on!

LUCIE: All right, I'll say it, This is officially not what I expected my first alien world to be like. I thought there'd be less bodies in the street for a start.

THE DOCTOR: Fewer bodies, not less.

LUCIE: Whatever. Red Rocket Rising. Funny name for a planet.

THE DOCTOR: I've heard funnier.

LUCIE: Go on then. Make us laugh.

DOCTOR: Everybody lives, Rose. Just this once, everybody lives!

CHARLEY: Come on. Take my hand.

DOCTOR: But we can see now. We don’t need to hold on to each other.

CHARLEY: I know. Take my hand anyway.

DOCTOR: I'm afraid I don't believe in curses.

CHURCHWELL: A rationalist?

DOCTOR: Not exactly. I just look for the best in people.

DOCTOR: You feel that pounding in your heart? That tightness in the pit of your stomach? The blood rushing to your head, do you know what that is? That's adventure. The thrill and the fear, and the joy of stepping into the unknown. That's why we're all here, and that's why we're alive!

DOCTOR: I love humans. Always seeing patterns in things that aren’t there.
