DOCTOR: I wear a Stetson now. Stetsons are cool.

DOCTOR: I'm being extremely clever up here, and there's no one to stand around looking impressed! What's the point in having you all?

RIVER: Couldn't you just slap him sometimes?

DOCTOR: Time isn't a straight line. It's all bumpy wumpy. There's loads of boring stuff like Sundays and Tuesdays and Thursday afternoons. But now and then there are Saturdays. Big temporal tipping points when anything's possible. The TARDIS can't resist them, like a moth to a flame.

RIVER: You're going to have to trust us this time.

DOCTOR: Trust you? Sure. But, first of all, Doctor Song, just one thing. Who are you? You're someone from my future. Getting that. But who? Okay. Why are you in prison? Who did you kill, hmm? Now, I love a bad girl, me, but trust you? Seriously.

DOCTOR: You're lying.

AMY: I'm not lying.

DOCTOR: Swear to me. Swear to me on something that matters.

AMY: Fish fingers and custard.

DOCTOR: My life in your hands, Amelia Pond.

NIXON: You were my second choice for this, Mister Delaware.

CANTON: That's okay. You were my second choice for President, Mister Nixon.

DOCTOR: I'm going to need a SWAT team, ready to mobilise. Street level maps covering all of Florida. A pot of coffee, twelve Jammie Dodgers and a fez.

AMY: Argh! I saw you before, at the lake. And here. But then I forgot. How did I forget? What are you?

DOCTOR: Jefferson isn't a girl's name. It's not her name either. Jefferson, Adams, Hamilton... River?

RIVER: Surnames of three of America's founding fathers.

DOCTOR: Lovely fellows. Two of them fancied me.

Doctor Song, you've got that face on again.

RIVER: What face?

DOCTOR: The "he's hot when he's clever" face.

RIVER: This is my normal face.

DOCTOR: Yes, it is.

RIVER: Oh, shut up.

DOCTOR: Not a chance.

DOCTOR: Life signs?

RIVER: No, nothing that's showing up.

DOCTOR: Those are the worst kind.

DOCTOR: Shout if you get in trouble.

RIVER: Don't worry, I'm quite the screamer. Now there's a spoiler for you.

RORY: What did you mean? What you said to Amy. There's a worst day coming for you.

RIVER: When I first met the Doctor, a long, long time ago, he knew all about me. Think about that. An impressionable young girl and, suddenly this man just drops out of the sky and he's clever and mad and wonderful, and knows every last thing about her. Imagine what that does to a girl.

RORY: I don't really have to.

RIVER: The trouble is, it's all back to front. My past is his future. We're travelling in opposite directions. Every time we meet, I know him more, he knows me less. I live for the days when I see him, but I know that every time I do, he'll be one step further away. And the day is coming when I'll look into that man's eyes, my Doctor, and he won't have the faintest idea who I am. And I think it's going to kill me.
