Selfless (Buffy the Vampire Slayer)
"Selfless" is the fifth episode of the seventh and final season of television series "Buffy the Vampire Slayer". Plot. Anya finally gets back into her old vengeance demon ways by helping a girl get revenge on an entire fraternity by having a spider demon tear their hearts out. Anya herself feels deep remorse about the event, even though Halfrek tries to encourage her to continue. Willow, returning to college, discovers the frightened and crying girl and the remains of the fraternity in the frat house, so she confronts Anya and offers her help in giving  up her vengeance work; but Anya acts stubborn and defensive. When Willow tells Buffy and Xander, all three fear the worst of Anya. Buffy is determined to kill Anya; Xander, who still loves her, cannot believe Buffy could do such a thing. Buffy and Xander track Anya back to the frat house, where the two women fight as Xander tries to stop them. Buffy stabs Anya, seemingly killing her, but Anya's demon side prevents her from dying. Willow calls forth Anya's boss D'Hoffryn, using the talisman he gave her while trying to recruit her as Anya's  replacement. When he interrupts the fight between her and Buffy, Anya begs him to reverse the spell she did – even though she knows the cost of reversing such a spell is the life and soul of a vengeance demon. Anya is ready to die, even if Xander does not want her to, but D'Hoffryn instead summons Halfrek and kills her, wanting Anya to live and suffer through her guilt rather than die. A distraught Anya leaves and tells Xander not to follow her, wondering what her purpose is outside of their relationship now that she is mortal again. Selfless (Buffy
