 Anya convinces an unsuspecting Willow to assist her with a spell that will return her amulet and, with it, her Vengeance Demon powers. Willow, sensing something wrong with the magic, balks at the last minute and disrupts the spell. Instead of returning the amulet, the spell summons the vampire Willow from the alternate universe where Anya s final wish took place and sets her loose in Sunnydale.
