Ben: Do you really think it's my fault that [my mother] died?
Roger: What do I know? Why do you keep looking at your watch? You got a date? Listen, if it makes you feel any better, I will do my best to remember your birthday next year.
Ben: I don't think that's gonna happen, Dad.
Roger: What do you mean?
Ben: You know, I've missed her too. Maybe as much as you have. But the difference is that, for as long as I can remember, I've had to put up with you. And doing that required a tremendous amount of patience. Goodbye, Dad. (Ben puts on a gas mask and opens a poisonous gas grenade in the van. Roger dies)
