I'm still a little unsure as to why Sam hates Clark so much. I thought that alt-Clark didn't know a thing about the Lois in his world until canon Lois came over and "introduced" herself, which ended up in breaking alt-Clark & Lana's engagement.

So alt-Clark has been looking for his Lois ever since... right? Or did you say in the fic that alt-Clark gave up looking for Lois and that's the reason that Sam hates him?
