Gilda: If you're worried about Johnny Farrell, don't be. I hate him.
Ballin Mundson: And he hates you. That's very apparent. But hate can be a very exciting emotion. Very exciting. Haven't you noticed that?
Gilda: You make it s.
Ballin Mundson: There is a heat in it, that one can feel. Didn't you feel it tonight?
Gilda: No.
Ballin Mundson: I did. It warmed me. Hate is the only thing that has ever warmed me.

Gilda: You're cock-eyed, Johnny! All cock-eyed.

Gilda: Got a light?
Uncle Pio: Yes, Mrs. Mundson. It is so crowded and yet so lonely, isn't it?
Gilda: How did you know?
Uncle Pio: You smoke too much. I've noticed. Only frustrated people smoke too much and only lonely people are frustrated.
