A novel concept, and also, Freebird backup stories

Now that Freebird is winding down on the final deathmarch-to-the-finish (except for the cover, oh god, the cover *cries*), I think there might be a nascent novel nibbling at my brain. Last night I got hit with a very visual scene, and before I knew it I'd written 3000 words of this thing. It involves characters from long ago that I still love intensely, and an urban fantasy idea that I don't think has actually been done yet. The plot's a snarled mess, and I still want to work on the other novel that I was talking to Jane about, but this one is nipping at my heels and wanting to be written. (And this one, unlike the other, has characters! Characters are always a plus!)

Oh choices, choices ...

Also, I'm currently working on ideas for backup stories for the Freebird book (to fill out the page count, basically). Are there any Freebird characters you're just dying to know more about? (The archive is here in case you need a refresher.) I'm already doing some filling-in of the blank spots in the characters' personalities and histories in the new strips -- there are about 30 all-new strips for the book, plus some of the old ones have been rewritten. So some of your questions might already be answered in the book! But I'd be very interested to know if anyone has anything specifically that they want to know about the characters, either in the present or the past, or any areas that they'd like to see explored.
