The Book of Averted Prophecy: Chapter I

I reserve the right to return to this at some point, but I've been sitting on it unsure if I'm going to finish it for years, so filing it under alternative paths seemed the Thing to Do.  (There are a few chapters after this.)  I at least have plans of finishing the other things not under that tag, even if they might go on hiatus for a while.
So.  Catch-up.  Season 7, the First affecting Spike, established Spike/Xander.  You can see where I've been just playing around with ideas, because there are elements in common with some of the Giles' Detective Agency works.  The whole world restart thing is a little Echoes of Our Hearts, and you can see where I settled on a Demonform for Xander (technically, I call it Dragonborn, so he might be half-dragon, but it's there).
I confess I've never seen Rocky Horror Picture Show; I know the song because several Halloween mixtapes include it (and it is a catchy song).

Main Points:
Buffy/Devil May Cry
