Quotes from "Time"

The Doctor: Okay, when does this Amy step inside the box? We need to maintain a timeline.
Amy-2: Ah, as soon as she slapped Rory.
Amy: Okay.
Rory: Huh. No, why do I get slapped?
The Doctor: Because we have to stick to the established chain of events. One mistake and the whole timeline could collapse. We'd end up with two Amy Ponds forever, and then what would you do?
(Rory thinks about it, Amy slaps him) 

Amy: Do I really look like that?
Amy-2: Yeah. Yeah, you do.
Amy: Umm. I'd give you your driver's license.
Amy-2: I bet you would.
The Doctor: Ohhh, this is how it all ends. Pond flirting with herself. True love at last. Oh, sorry Rory.
Rory: Absolutely no problem at all.

The Doctor: Okay, we're back in normal flight. The TARDIS is no longer inside itself, the localized time field is no longer about to implode and rip a hole in all casualty. But just in case... Pond, put some trousers on.
