I need some help looking for a fic were Xander dresses as Sepiroth for haloween. After it's over Sepiroth (who is still batshit crazy) and Xander share the same body and go around the US dystroying stuff and killing people including the inititve boys. Eventually they try to wake the wepons the fell on earth and in doing so come into contact with Gaia then they start to call her mother. If any of you can find it I'd appreciate it.
