1) Loki didn't get much of a chance to see him coming.irishda said:Loki's tricked Thor before with that whole clone thing. Yet, somehow he didn't think the Hulk was a big enough threat to use on him, even though he was counting on the Hulk to take down the entire superhero team. Plus he apparently decided to never get up and walk away at any point.
Everyone keeps pointing their guns at Bruce Banner, even after he just gets done telling them he put a gun in his mouth and the Hulk just spit the bullet out. That one really ground my gears.
If Bruce Banner's always mad, why isn't he always the Hulk. (face it, they wanted to give him something cool to say, but it doesn't make any sense)
How come Fury didn't dispatch any of those soldiers he's got all over the carrier with some experimental weapons Agent Coulson had? Even if they just had the one weapon, those elite soldiers would probably have been at least as helpful as the girl with a pistol and the guy with a bow.
2) Because he's shit scary and not everyone heard him say that. Only the main characters were in the room. It's easy to forget that the viewer can have more information than some of the characters.
3) He can control his emotions because as he demonstrated right after that line he learned how to bring out the Hulk at by his out accord and 'direct' his rage. When he transformed in the Heli-carrier attack he was pushed over the edge into direction-less rage. This is because he was already mad from the argument with the other avengers, the sudden attack on the ship would have got his heart pumping and he was likely injured when he fell through the floor.
4) It was an untested prototype. Plus he wasn't near an armoury, he was cornered in the flight deck.
