"I don't think he would." Tony leaned forward, looking at Bruce solemnly, "Bruce... You controlled him. You somehow communicated to him that I wasn't a threat, and that saving me was good. I know you were in there somewhere, watching me fall, and you somehow told Hulk that I was gonna die unless you and he did something about it. And viola, I'm still around."
"I trust you, and I trust the Hulk part of you." As far as Tony was concerned, that was that, and he was determined to help Bruce accept the Hulk as much as he had.
