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: 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: 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: Well, I am that mysterious adventurer in all of time and space, known only as Doctor Who. And these are my disposables, Exposition and Comic Relief.

ROMANA: K9 is a vicious robot criminal from the fifth galaxy. Aren’t you, K9?

K9: Affirmative!

TARDIS: Friendship is standing shoulder to shoulder in the face of life and death. Friendship is there when love's candle has burned and gutted. Friendship stays loyal when the enemy is at the gates. Friendship is never sacrificed, never surrendered. I was your friend.

BERNICE: So, do you have a girlfriend?

DOCTOR: No.

BERNICE: Boyfriend?

DOCTOR: No

BERNICE: Model Railway Set?

DOCTOR: Somewhere. The TARDIS is full of surprises.

BERNICE: But you’re not the sort of person that keeps a big table, with tiny trees and signal boxes and things?

DOCTOR: No.

BERNICE: Ah, then you must be interested in law and order.

DOCTOR: No. I like chaos. Big explosions. Rebellions. That sort of thing. Why do you ask?

BERNICE: Because I want to know why you go around in a police box!

DOCTOR: You know what one is?

BERNICE: It’s from my favourite era.

DOCTOR: I could’ve changed it ages ago. But I like the shape. And the motto. Call here for help. That’s what I do. I let the little children sleep safely at night, because I’ve searched through all the shadows and chased the baddies away. I’m what monsters have nightmares about! But everybody’s a monster sometimes. We all do things we regret. And sometimes we have to lose things very precious to us.

COUNTESS: I was rather under the impression that Mister Duggan was following me.

DOCTOR: Ah. Well, you’re a beautiful woman, probably, and Duggan was trying to summon up the courage to ask you out to dinner, weren’t you, Duggan?

MASTER: Doctor, why don't you come in with me? We're both Time Lords, we're both renegades. We could be masters of the galaxy! Think of it, Doctor, absolute power! Power for good. Why, you could reign benevolently, you could end wars, suffering, disease. We could save the universe.

DOCTOR: No, absolute power is evil.

MASTER: Consider carefully, Doctor. I'm offering you a half-share in the universe.

DOCTOR: Even after all this time he cannot understand. I dare not change the course of history. Well, at least I taught him to take some precautions. He did remember to look at the scanner before he opened the doors. Now they're all gone. All gone. None of them could understand. Not even my little Susan, or Vicki. And as for Barbara and Chatterton. Chesterton. They were all too impatient to get back to their own time. And now, Steven. Perhaps I should go home, back to my own planet. But I can't. I can't.
