Oh, you have GOT to give us more on this one! There are so many possibilities, so many complications, so many questions. What did Lois overhear? Who's taking care of the kids while he's working (maybe his parents? maybe Cat Grant?)? Will he and Lois be drawn closer by this development? When will Lois meet the kids? (Surely he'll introduce them!) What happened to the "other" Lois and Clark? Was it something natural, or was it a threat that will follow the children to their new home world? Oh, please come back with the rest of the story!
This is really brilliant,Queenie - if you finish it. Otherwise it's just a frustratingly tantalizing fragment, filled with amazing possibilities. If you need a co-author, ask for volunteers. (I think my muses would be interested (hint-hint wink-wink nudge-nudge).)
