Clint smirked. It wasn't the first time someone would assume he wasn't bright just because he was known for shooting arrows. Sure he wasn't as brilliant as Tony or a doctor like Bruce, but he wasn't an idiot, and he did like to watch things. "Hawkeye" was more than a nickname, really...his eyes were keen and he liked to observe before acting, especially when learning. He listened to every word Bruce spoke, even to the point where he trailed off.
"Trying to control the Other Guy without being angry all the time, huh? Hopefully your tests come to better conclusions for whatever results you and Tony can produce." He shook his head. "It's not boring, it's interesting...but, if you need to talk to Tony, I don't mind."
