Hi Bek!
Gah! He'll need a bigger Fortress then. That treehouse will just not be enough.
There's
Bidding for Attention by Wendy Richards actually, now that I think about it

And
Nowhere to Run by ML Thompson. So, anyway, I can just see Lois sitting there and complaining about the lack of amenities and Clark needing to expand the treehouse.

Michael
I have read Bidding for Attention

but not Nowhere to Run....
Click..... hmmmm.... grabs popcorn and settles in with her reading glasses... Clark totally should build a Fortress of Not-Quite-Solitude for the two of them, with all the amenities...
