Michael Ward: Did you ever want to kill a man?
Martin: My son, there's murder in every intelligent man's heart.
The Stranger: I want a couple of hamburgers... and I'd like them raw.
Jane: Why do they want to lock you up?
The Stranger: So they can hurt me. They put you in a shirt with long sleeves and they pour ice water on you.
The Stranger: They send you to take me back?
Jane: No, who?
The Stranger: Don't you know? The people who lock you up.
