I think Jimmy has had a crush on Lois in some other show or movie.. can't remember which either. I think it's pretty cute even though I ship Jimmy/Chloe.

I didn't like Chloe until season 5 when Chloe prooved to be a true friend to Clark. I liked her a lot more when she started to give up on Clark but still being there for him as a friend. That's why I don't like Clark/Chloe, because it would cheapen Chloe as a character if she protected Clark just because she was in love with him. IMO Clark/Chloe was over by season 5 (despite the kiss but they never followed up on that) which was when Chloe began to grow as a character.
