You think I'm going to listen to you! Stark said you were a traitor, so I'm taking you down!
You've never listened to anyone! Not me, and sure as heck not Iron Man! And now, you're just going to blindly follow orders? You've never done that in your life! And now you're going to get yourself killed, because Tony Stark told you to? No one tells Hawkeye what to do! Come on, Clint!
