Breakdown-
This is at university of Illinois in bromley hall which is a private dorm. For some reason the makers of bromley decided that a room made with glass walls in a college environment was a great idea.
Anyway, the girl and guy are sparring in some kick boxing (both ROTC kids) and the girl was showing off some self defense moves i guess. So slowly a crowd began to gather around the fight and this kid with a gay umbrella starts knocking on the glass wall with it.
Obviously the kids never been to a zoo or aquarium cause thats like the first thing they tell you to not do. So the girl tried knocking on the glass to scare him and the guys like "move over babe, im a total alpha male" and meant to knock on the glass but accidentally fully followed through with his punch. Shattering the glass wall and getting glass on the beta kids face. Got a couple lil cuts but hes aright.
