Yeah, definitely not. And with Lavon and AB's situation, there were feelings lingering between them through most of season 3 so it didn't make much sense for Lavon to randomly still love Lemon after all that time. It seemed they tried to make it seem like they always loved each other because Lavon once told Lemon that "they could put their feelings aside for as long as they want, but it doesn't mean they aren't there", BUT Lavon loved 2 other women after her so....
