"Bruce..." but before Steve could even say anything, Thor was furrowing his brow and looking fairly confused.
"The Hulk is a mighty warrior! You are a mighty warrior! It is a fair few who can say they may be able to take on me and my mighty Mjolnir! Without you, we would have been lost that day. Without you, one of our own would have been gone," he nodded to Tony. Yes, he may have been able to catch Tony, but maybe not. He didn't say he doubted his own power though. Steve had to smile at that speech knowing fully that Thor had gotten smacked around by the Hulk pretty good.
"I agree, Bruce. But your part in this team doesn't have to be just as the Hulk. You're a great scientist, I'm sure I speak for all of us when I say we would benefit greatly from having a mind like yours working with us."
