I saw this thread while Googling "bully characters", and I didn't see it in the list of threads in the folder it's in. So I hope it's alright to post here lol.
For Petey and Gary, I think they ended up getting married. I mean, the game makes it look like there's something between them at the very beginning lol.
Loved the part where Gary was picking on Petey. "Oh Marissa! Let me see your breaststroke! Or is it the guys you wanna see Petey?"
