Heroes Season 2 Episode 8

Adam: Peter, what the hell was that?
Peter: Do you know me?
Adam: Of course, I know you. Peter it's me, Adam. Don't you remember. Together we're going to change history.
Peter: I'm sorry. I don't.
Adam: I see the Haitian has taken liberties with your mind.
Peter: The Haitian?
Adam: That explains why you fell off the face of the earth. But you can get back your memory. I know how.
Peter: How?
Adam: Healing. You can do what I can do. Which means the mind has to repair itself.
Peter: How do you suggest I go by doing that?
Adam: Think about what matters most to you. Do you know what that is?
(Peter pulls out a picture of Nathan and him from his pocket)
Adam: His name is Nathan.
Peter: Nathan. (breathes in deeply) Nathan.
