Having physically transformed into Warren Mears, whom she tortured and flayed in a rage over the murder of her girlfriend Tara Maclay, Willow seeks help from the UC Sunnydale Wicca Group and discovers that Amy is a member. Amy explains that she had hit "rock bottom", and was doing much better now. It is soon revealed, however, that Amy is in fact responsible for Willow's transformation, the result of a hex placed on her apparently out of jealousy and spite. However, in the Season Eight comic book, it's made known this seemingly random event is actually part of a larger plan orchestrated by Warren, after Amy rescued him from death in the earlier episode "Villains."
