“Demons run when a good man goes to warNight will fall and drown the sunWhen a good man goes to warFriendship dies and true love liesNight will fall and the dark will riseWhen a good man goes to warDemons run, but count the costThe battle's won, but the child is lost”

“Madame Kovarian: The anger of a good man is not a problem. Good men have too many rules.The Doctor: Good men don't need rules. Today is not the day to find out why I have so many.”

“Don’t be that kind of person who goes about falling in love everywhere.”

“Never run when you're scared. Rule 7.”

“I'll be a story in your head. That's okay. We're all stories in the end. Just make it a good one, eh? 'Cause it was, you know. It was the best. The daft old man who stole a magic box and ran away. Did I ever tell you that I stole it? Well I borrowed it. I was always going to take it back.”

“Though the man above might say hello, expect no love from the beast below”

“When you run with the Doctor, it feels like it'll never end. But however hard you try you can't run forever. Everybody knows that everybody dies and nobody knows it like the Doctor. But I do think that all the skies of all the worlds might just turn dark if he ever for one moment, accepts it. Everybody knows that everybody dies. But not every day. Not today. Some days are special. Some days are so, so blessed. Some days, nobody dies at all. (In the library, the Doctor walks back to the TARDIS. He stops, looking at the doors. Then he raises his hand, and stands there poised like that for a long moment. Finally he snaps his fingers. The doors open. He smiles slowly and walks in, joining Donna. Then he snaps his fingers again, and the doors close. River's voice continues over this.) Now and then, every once in a very long while, every day in a million days, when the wind stands fair, and the Doctor comes to call... everybody lives.”
