Re: Bruce B/Steve R
He had a full on nervous breakdown, Steve. I wasn't there, but from what I know there was a fight going on, you were trying to mellow the bad guy out, Hank got twitchy and took a shot, which started everything all up again. He almost died until his wife saved the day.
The Avengers went for a court martial, and he continued going crazy. Built a robot, tried to kill everyone (with the intention of saving them in the end), beat up his wife, and went completely bonkers. Like...Completely. But he got better. It took a long time, but he got better. I'm guessing by what you just said he's not exactly better in the here and now.
