It would be to their advantage to have a smiling nice Bobby that flashes back and snaps, then switches to normal nice smiling guy. Somewhat like a serial killer. Something happens in the match that flips his switch. He gets tied up in the ropes or some shit just like his siblings tied him up in the woods and dude just loses his fucking mind and gives someone a savage beatdown to the point that the crowd gets a bit uncomfortable. Maybe have the locker room clear out to pull him off and him get up and act like nothing happened.
