OH, WOW, IT'S BARB! Barb is one of us, too. She's a good writer, and we love her. (So yes, you do need to start writing again I remember that fic you started... sad, but so well-written.)
Bringing up the hints really makes me wonder--when were they last in an episode, anyway?
I did catch a few of the Chronicles eps (mainly because parties who knew I was interested let me know that they were coming up), but I can't remember when they were last in the show. Did they show up at all in Advance? DP? Any of those later movies? Man, I am behind. I would assume that they're about to make a cameo with this new season coming up.
If they haven't shown up for a while, that makes sense. Ash is growing up and changing and not wanting/ needing to check in with the parent. (That also means we can just read it as "Having Uninterrupted Potential Love Nest, Yahoo" for a while and go from there.)
