Watching it several times again, you see the fan walk past and Brown is clearly making his way toward the guy. Comes up from behind and left hooks the dude in the backside of his medulla oblongata. Still curious what prompted that. Did the guy smart off to Brown as he went past? Did he push Brown or bump into him? Just wondering because something happened to cause TB to pursue that one guy.
That said, unless this kid punched him, kicked him, threw something on him, then Brown went full thug mode. I want to represent the kid. I'm pretty sure he lost partial vision in his left eye, was concussed and fractured his dick from that punch.
