Imagine: Bruce silently admiring you.

Tony had just come into the lab you and Bruce had been working in. He had his classic smug look on his face as he annoyed you and Bruce. After a while, it got annoying and you snapped.

"Tony I don't want to hurt you, but I will if you keep talking. Now if you don't mind, Bruce and I are trying to work, so if you and your cocky attitude could get out of our lab that would be great."

Bruce looked up at you proud of you as Tony mocked hurt and left the lab.
