Amy: But he (the Doctor) was dead.
River: Who told you that?
Amy: He did.
River: Rule one: the Doctor lies.
River: He said no one could save him. But he must have known I could.
The Doctor: Rule one: the Doctor lies.
River: Okay. I'm going to tell you what I probably shouldn't. The Doctor's last secret. Don't you want to know what he whispered in my ear?
Amy: He whispered his name.
River: Not his name, no.
Amy: Yeah it was. He said it was.
River: Rule one?
Amy: The Doctor lies.
