I honestly have no problem with Fatboy and actually actively like him but that's partially because he's never been thrust into the forefront of the show for too long. Fatboy does no harm as a supporting character, even without Dot he was involved with Donna a little bit recently and also seems to be Charlie's only proper friend as well. I honestly don't see him going anywhere for quite a while to come, especially since I have this weird feeling that June Brown is extremely fond of Ricky, it'd at least help explain how he was still brought back into the fold after his suspension controversy.
