As a scrum was unfolding in the corner, Hyman and Benn stood just inside the blueline, looking fairly friendly as they held each other back from the scrum to avoid any odd-man situations, one arm around each other. As they disengaged, Benn chopped the stick out of Hyman's hands. Hyman flashed him a look like "seriously, bro?" and then as he went to pick up his stick, Benn grabbed him by the collar and the pushing and shoving began.
Benn thrives when playing this style of game, so it's no shock to see him mixing it up. As far as the interaction itself, it went from relatively friendly to pretty dicey in a real hurry.
