Clark: Are you ever afraid?

Bruce: No.

Clark: Not even of dying?

Bruce: No.

Clark: You don’t feel any emotion about it one way or another?

Bruce: No. I have to stay functional until my mission is complete. Then it doesn’t matter.

Clark: Yeah. I have to stay functional, too. I’m “too important”.
