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.

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.

RIVER: So, assuming tonight is all we have left.

DOCTOR: I didn't say that.

RIVER: How long is a night on Darillium?

DOCTOR: Twenty four years.

RIVER: I hate you.

DOCTOR: No, you don't.

DOCTOR: We all change, when you think about it. We're all different people all through our lives. And that's okay, that's good, you've got to keep moving, so long as you remember all the people that you used to be. I will not forget one line of this. Not one day. I swear. I will always remember when the Doctor was me.

DOCTOR: I walked away from the last Great Time War. I marked the passing of the Time Lords.

I saw the birth of the universe and I watched as time ran out, moment by moment, until nothing remained.

No time. No space. Just me.

I walked in universes where the laws of physics were devised by the mind of a mad man.

I've watched universes freeze and creations burn. I've seen things you wouldn't believe. I have lost things you will never understand.

And I know things. Secrets that must never be told. Knowledge that must never be spoken. Knowledge that will make parasite gods blaze.

So come on, then. Take it! Take it all, baby! Have it! You have it all!

DOCTOR: I'm not running away. But this is one corner of one country in one continent on one planet that's a corner of a galaxy that's a corner of a universe that is forever growing and shrinking and creating and destroying and never remaining the same for a single millisecond. And there is so much, so much to see, Amy. Because it goes so fast. I'm not running away from things, I am running to them before they flare and fade forever. And it's all right. Our lives won't run the same. They can't. One day, soon maybe, you'll stop. I've known for a while.

NAZI OFFICER: What are you doing here?

RIVER: Well, I was on my way to this gay Gypsy Bar-Mitzvah for the disabled, when I thought gosh, the Third Reich's a bit rubbish. I think I'll kill the Fuhrer. Who's with me?

NAZI OFFICER: Shoot her.

DOCTOR: Courage isn’t just a matter of not being frightened, you know. It’s being afraid and doing what you have to do anyway.

DOCTOR: One day, I shall come back — yes, I shall come back. Until then, there must be no regrets, no tears, no anxieties. Just go forward in all your beliefs, and prove to me that I am not mistaken in mine. Goodbye, Susan, goodbye, my dear.
