Bruce Wayne: Too expensive for the Army?
Lucius Fox: I don't think they tried to market it to the billionaire, spelunking, BASE-jumping crowd.
Bruce Wayne: Look, Mr. Fox.
Lucius Fox: Yes, sir?

Lucius Fox: Mister Wayne, if you don't want to tell me exactly what you're doing, when I'm asked, I don't have to lie. But don't think of me as an idiot.
Bruce Wayne: Fair enough.
