>>79024182The reality is a lot of comedy-centric shows rely on their characters keeping the traits that make them funny or stand out. Idiots will remain idiots, snobs will remain snobs, selfish will remain selfish, etc. The cast of Seinfeld never got over their flaws through its run, and in KotH you Dale remaining the paranoid nut and Bill remaining the sad, awkward man (at least until the very end of the show, where it wouldn't matter as much).
I think the best you can hope for is that even if Timmy keeps on making stupid wishes, he'll still have plenty of scenes where he and Chloe are just having a good time and enjoying each others company.
