You know, except for Lois's age-inappropriate clothing (which, given her new circle of friends, might not be so inappropriate), as long as Clark takes her home first - with Jonathan in the front seat and Lois in the back with Martha - I don't see anything indecent about that. It's certainly more appropriate than the homecoming Claude had planned for her.
I like the idea that Clark would believe that Lois was a narc. It fits, and it might even help her cover. If he thinks she's looking for drugs and dealers, he'd be far more inclined to protect her cover story. So no, I don't think you have a problem with your story.
Lois, however, is going to have to tie Lucy to a chair and duct-tape her mouth closed. Otherwise there'll be a murder in the Lane household tonight. And Lois better hope that her mother is sober enough not to spill the beans!
It's getting better and better, Laura. Keep it up!
Oh, yeah, almost forgot. Claude is a @#$%^&*()&^%!
