OCTAVIAN: Doctor Song, I've lost good Clerics today. You trust this man?

RIVER: I absolutely trust him.

OCTAVIAN: He's not some kind of madman, then?

RIVER: I absolutely trust him.

DOCTOR: A forest in a bottle on a space ship in a maze. Have I impressed you yet, Amy Pond?

RIVER: Father Octavian, when the Doctor's in the room, your one and only mission is to keep him alive long enough to get everyone else home. And trust me, it's not easy. Now, if he's dead back there, I'll never forgive myself. And if he's alive, I'll never forgive him. And, Doctor, you're standing right behind me, aren't you?

DOCTOR: Cracks. Cracks in time. Time running out. No, couldn't be. Couldn't be. But how is a duck pond a duck pond if there aren't any ducks? And she didn't recognise the Daleks. Okay, time can shift. Time can change. Time can be rewritten. Ah. Oh! ... ... Time can be unwritten.

OCTAVIAN: Listen to me, it's important. You can't trust her.

DOCTOR: Trust who?

OCTAVIAN: River Song. You think you know her, but you don't. You don't understand who or what she is.

DOCTOR: Then tell me.

OCTAVIAN: I've told you more than I should. Now please, you have to go. It's your duty to your friends.

DOCTOR: Just tell me why she was in Stormcage?

OCTAVIAN: She killed a man. A good man. A hero to many.

DOCTOR: River Song, I could bloody kiss you.

RIVER: Ah well, maybe when you're older.

AMY: Then why do I remember it at all? Those guys on the ship didn't remember each other.

DOCTOR: You're a time traveller now, Amy. It changes the way you see the universe, forever. Good, isn't it?

RIVER: You, me, handcuffs. Must it always end this way?

DOCTOR: Octavian said you killed a man.

RIVER: Yes, I did.

DOCTOR: A good man.

RIVER: A very good man. The best man I've ever known.

DOCTOR: Who?

RIVER: It's a long story. Doctor. It can't be told, it has to be lived. No sneak previews. Well, except for this one. You'll see me again quite soon, when the Pandorica opens.

DOCTOR: The Pandorica. Ha! That's a fairy tale.

RIVER: Doctor, aren't we all?

DOCTOR: Can I trust you. River Song?

RIVER: If you like. Ha, but where's the fun in that?
