This is an AU video set during Buffy the Vampire Slayer: Season 8 and Angel/Spike: After the Fall. Features Buffy, Angel, Spike, and it's set in Melaka Fray's future. I'll post the description in comments.
This is a fan video made by BadFred of youtube after being so excited by the Spike and Illyria pairing in Spike: After the Fall. It's set to Hysteria by Muse and uses clips from Buffy the Vampire Slayer and Angel as well as other shows.
