Clark was silent for a long moment. “That’s not exactly what I was expecting to hear. Can I ask why?”
I point this line out because it's very unlike Clark; however, you've given us quite a different Clark. One who's overcome quite a lot to get where he is. He wasn't sheltered by the love of his parents, and he's had some hard living to do, but he's battled through that marvelously to become a wonderful and intriguing person. I think what I'm trying to say is, you've really painted a brilliant picture of a completely different Clark Kent. And I can *hear* his tone, and up front manner, and it fits wonderfully with the Clark you've created. Did that make any sense? :p
“Then we can just be passing through. I could pretend to be your fiancé.”
The idea had popped into her head with a flash of inspiration. “You could just pretend to be coming home for a visit. Simon doesn’t know me by appearance…I could just pretend to be the little woman.”
Whee! I like that idea.
She should know; she’d had that with Lex, before he was killed.

What?!
“You wouldn’t want to do that,” Clark said, turning to watch the road once again. “I didn’t exactly have a happy childhood in Smallville.”
Lois grinned. “So you were a nerd in high school? It’ll do your reputation a world of good to be seen with a woman like me.”
Oh boy... Lois doesn't have a clue what she's getting into... not that I have any more than an inkling... Eeps!
Okay, Shayne, I'm all caught up!! Ready for the next part.

I'll try not to fall behind again.
Oh... and since you asked... I think this definitely should stay as one story! I agree with what Yvonne said.
