This is a brilliant, thought provoking piece. The idea of Xander making a training video had me believing this was going to be a light hearted read but I got a chill with this passage: Willow had told him once, offhandedly, as if she was thinking about something else, about the kind of magic you could do with the blood or the bone or the eyes of a slayer. He’d thought of Buffy first. The one true slayer. The true horror had only rolled, ice cold, across his brain when his eye had caught, through the window, a group of the new slayers giggling on the grass.

Seamlessly segueing from that scene to a visit with witches not fortunate enough to have a Xander to talk them down from their magical near apocalypse worked beautifully. Willow could easily have been one of those empty eyed women and it's no wonder Xander wants to make sure there's a safety net in place next time. Willow may think she's paid for what she'd done, but Giles and Xander and Buffy are still paying the price for her hubris. Beautifully done.
