Was Piper living in Vancouver? I assumed she would have moved down to LA with her mom.
I just finished my re-watch of season 8. I'm not going to get into the storylines, but what ticked me off was DD's name coming up first in the credits in the episodes he came back for. I also watched the promo spots on the DVD, and was really annoyed that for those episodes, the announcer would make a big point of saying "Starring David Duchovny!" and there would be a shot of him standing in front, with Scully and Doggett in the background.
