1) Midway thru the story spike & xander buy a house ( i don't remember in what city) that is occupied by pink demon mice that xander names dice, they seem to come from some sort of opening in the attic
2) also has a wesley/gun pairing, where wesley has become part water, or amphibeous demon as the backlash of some spell that happened before the story. Wesley & Gunn eventually move in with spike abn
3) spike & xander sleep in a "nest" of pillows that they call " the next" & devote a room to
i think i may have originally found it on stepaway from my xander (which is now long gone, of course)
if anyone can help I'd appreciate it!
