Ben Cortman: Who is it?
Robert Morgan: It's me, Ben! We're late!
[Ben answers the door]
Robert Morgan: Ben, what's the matter with you?
Ben Cortman: Nothing and I'm going to keep it that way.
Robert Morgan: Ben, look, let's talk about this.
Ben Cortman: There's nothing to talk about. You think I'm out of my mind. You laughed at me and my theory. You might be one of them.
Robert Morgan: Ben, look, you're ill. You ought to see a doctor.
Ben Cortman: No doctors! You take care of your life, I'll take care of mine. Now get away from here. You understand, get away from here!
