Clark is affected by red krytonite in season 1 before even knowing about the green stuff and he sleeps with Cat as Clark and then with Lois as Superman. The real challenge here is this: what happens next and how does Clark deal with the consequences?
Things I want in the fic:
A pregnancy scare for Cat, but no actual pregnancy. It affects her worldview dramatically.
An Elvis story from Perry to Superman.
Jimmy realizing that Clark and Superman are one and the same, and that he's been with both Lois & Cat within 24 hours of each other.
A side plot of Lex Luthor running for President of the US against Bruce Wayne.
Things I don't want in the story:
Jonathan Kent.
Jack.
Anything beyond the known laws of physics with the obvious exception of Superman.
