N o ! There must have been something. We just all missed it. The writing can't really be that bad!
I think the case is a bit different with Jonathan, though. I can imagine that as a parent you're very critical about the friends your son/daughter hangs out with. Jonathan disliked Lionel so much that he just never could ignore the fact that Lex was Lionel's son, no matter how many times Lex proved himself trustworthy. So at least, with Jonathan it makes some sense. Chloe on the other hand...
