Rory: Seriously? You?
The Doctor: Do you ever remember it? Two thousand years waiting for Amy? The Last Centurion.

The Doctor: Are you lying?
Rory: Of course I’m lying.
The Doctor: Of course you are. Not the sort of thing anyone forgets.
Rory: But I don’t remember it all the time. It’s like this door in my head. I can keep it shut.
