The Hulk does not like this idea at all. He's only now learning the value of friends, but he likes it when people aren't mean to him, and he likes it even more when they aren't afraid of him. Iron Man's always been so easy with him, and the Hulk can sense that, not that he realizes it in so many terms.

"I'm not people. We're friends." And stupid Banner's not going to change that.

He frowns, trying to tug at the connection to Banner, trying to see what's wrong, but that's not really reliable.

"What happened?"
