JERICHO: YOU ARE OBSERVED! And that is my power over you!

RIVER: When you love the Doctor, it's like loving the stars themselves. You don't expect a sunset to admire you back. And if I happen to find myself in danger, let me tell you, the Doctor is not stupid enough, or sentimental enough, and he is certainly not in love enough to find himself standing in it with me!

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.

RANI: What if he's not there at all? What if it's just the two of us left in the whole wide world?

CLYDE: Like Adam and Eve.

RANI: Yeah. No! There's got to be someone else. There's got to be.

DOCTOR: ...in doing so, you make it happen. Anything I do just makes it happen.

GWEN: There's one thing I always meant to ask Jack. Back in the old days, I wanted to know about that Doctor of his. The man who appears out of nowhere and saves the world. Except sometimes he doesn't. All those times in history when there was no sign of him, I wanted to know why not. But I don't need to ask any more. I know the answer now. Sometimes the Doctor must look at this planet and turn away in shame.

It reminded Sade of some of the aristocrats, who had treated imprisonment as a bad joke, a mild annoyance that would be made right before any real damage was done. They had kept their dignity right up to the moment when the drum roll stopped and the blade fell. Then, too late, they screamed like children.

As I would have done. The thought popped unwelcome into his head.

SONGSTEN: Harsh words are like blunted arrows. It is the truth that makes them sharp.
