I stumbled over your story accidentally and love it.

Xander is going to be hugely pissed off, whenever he gets his brain back and ... damn ... I often got the sense that the 'superheros' of the shows short shifted him but they are certianly turning out to be truly arrogant (in the way folks who are 'speical' sometimes become) jerks on this one. THen screwing the whole pooch and leaving Spike (another low status person in the troop) to handle the messy, emotionally painful aspects of it.
