OH OH OH!!!!!
We can get an overlap episode, Forest Gumping everything to show how lois has ALWAYS known since she fund him (in a crater?) naked in the middle of a corn field? Y'Know who what the the same they did with Lost every other episode to show the complete relevance of new characters to EVERYTHING that had ever come before.
I might actually like Lois more if she's been a bigger ass than then she intended to help Clark gloss over his secret for the most part, however when she found out oliver was green aeeow, she tried to hide it from Clark... Great shades of inception! A Bluff in side a bluff?
