Bruce Banner: I don't think we should be focusing on Loki. That guy's brain is a bag full of cats. You can smell crazy on him.
Thor: Take care how you speak. Loki is beyond reason, but he is of Asgard. And he is my brother.
Natasha Romanoff: He killed eighty people in two days.
Thor: He's adopted.
Steve Rogers: Sometimes there isn't a way out, Tony.
Tony Stark: Right, I've heard that before.
Steve Rogers: Is this the first time you've lost a soldier?
Tony Stark: We are not SOLDIERS! I am not marching to Fury's fife!
Steve Rogers: Neither am I! He's got the same blood on his hands that Loki does. But right now we've got to put that behind us and get this done.
