Bear you could play at his own game if you're willing to go far enough. Heavy D... I'm pretty sure is just genuinely stupid. I doubt he'd understand anything other than being hit with a plank of wood.
Although he seems to have some sort of genuine deep-rooted issue with food, so there might be an angle there. I thought he was joking / deliberately being defiant when he took the piece of cake that Bear was tempting him with (when he was supposed to be on slop)... but then he seemed so genuinely grateful and completely abandonned all animosity when Aubrey and Renee gave him... some extra peppers?? His face... it was like it was christmas
