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?
