I saw no problem with that, tbh.
First off, did Severson see the head-shaking? And if he did, did he know it was directed at him? If I was in his skates, I wouldn't know myself but at the same time I would be more disappointed in the outcome of the game to think about things like that regardless.
Besides, teammates get on other teammates all the time. Just 'cause you're a rookie doesn't prevent you from acting like a teammate who is upset at another teammate for a bad play.
I'm sure Kinky had seen the replay by now and saw it was a bad deflection so he probably went "my bad" to Damon later on anyway.....(and that's IF Damon knew that Kinky was shaking his head at him)
