At the end of the episode, Jim takes Georgie back as an employee so I don’t know where the whole resentment came from. Jim realize that Georgie was right about the tires. Georgie realize that the competition was a guy who liked Mandy’s mom and we’re still making rude comments about her and he wasn’t gonna stand for it cause he’s a southern gentleman and he told Mandy’s mom about it, but never told Jim. I don’t think this will have anything to do with the break up and even if he did inherit Jim’s store. It’s not like he can’t change the name of the store with or without Jim’s blessing. I mean they’re only 11 so then there’s a lot to go.
