Melanie: You're not just a telepath. You can control objects with your mind.
David: Control may be an overstatement.

David: How do you know they won't kill her?
Syd: Because she's bait.

Cary: You have an extremely large amygdala.
David: Thanks.

David: We're having a romance of the mind.

Syd

Ptonomy: Melanie thinks you're the key.
David: To what?
Ptonomy: To winning: the war, and other things.

Melanie: David, your whole life people told you that were sick. What if I told you that's a lie? What if I told you, every memory you have of mental illness: voices, hallucinations, was just your power? And what if I could do more than just tell you? What if I could show you? Help you re-write the story of your life?

David: I have to know. Are you real?
Syd: I'm real. This is real, OK? I'm here. I came back for you. I love you. Are you gonna say it, too?
David: I love you.

Lenny: Don't worry about me. It's you that's got problems. They're coming for you, babe.
David: Who?
Lenny: They know about the hospital - what you did.
David: I didn't.
Lenny: What she did when she was you. Had your powers. They're coming and they're gonna kill you.

Lenny: Stop looking at me like that, man. I know- I'm dead - you killed me. And I gotta say, not cool, man.
David: I didn't.
Lenny: Yeah, you did. Don't blame her. Don't blame her - she was just a passenger, riding around in your body. Don't give a newbie a bazooka and then be surprised when she blows shit up.

The Interrogator: Stop. Would you say that again?
David: I said I looked in the mirror and I was her.
The Interrogator: Who?
David: Sydney.
The Interrogator: She was there with you?
David: No, somehow we - she took my place and I took hers when we kissed. But it wasn't me - I didn't do - it was her power - I think.

If the readings are right, he may be the most powerful mutant that we've ever encountered.

David: It's just Thursday. Like the 260th Thursday as a passenger on the cruise ship "Mental Health." On the plus side I've mastered eating with a spoon.
