Season Six was the first of two seasons in which Buffy aired not on the WB Television Network, but on the United Paramount Network (UPN). Giles decides to return to England months after Buffy's death, but on the same day, her friends resurrect her through a powerful spell, believing that her mystical (as opposed to a natural) death in Glory's portal meant that she might have been sent to hell (although never elaborated upon in an episode, this belief actually has a reasonably good basis, inasmuch as the ensouled Angel (instead of the evil Angelus) was sent to hell following his death in Acathla's portal in Season Two; in Season Seven, the ensouled Spike would also be sent to hell following his death in the First Evil's portal). The season deals largely with her sorrow at being in fact torn from heaven. Buffy finds a job at the Doublemeat Palace as she finds herself again in the daily grind (almost literally in the episode "Doublemeat Palace"). Buffy eventually begins a violent relationship with Spike, which brings momentary relief from her struggles. She is consistently tormented by The Trio, three nerds from Sunnydale High who have joined to take over the town in an effort that goes from being inane to truly evil. Jonathan, who was featured in earlier seasons mostly as a victim, joins Warren, the architect of a robot girlfriend in Season Five, and Andrew, whose brother Tucker sent Hell Hounds to the Prom in Season Three. A persistent subplot involves Willow and her growing abuse of magic. After she is forced to face with the consequences of her addiction, she attempts a difficult withdrawal when her lover Tara is accidentally killed by Warren. Willow descends into darkness and begins a destructive rampage, at first to avenge, but later to relieve her own suffering by bringing on an Apocalypse. Xander's unconditional love brings her back and saves the world. Spike eventually insists that Buffy admit she loves him. When she refuses, Spike attempts to rape her as a way to resume their no-means-yes sexual affair. He then leaves Sunnydale seemingly in search of vengeance, but is awarded his soul after painful trials instead. Rupert Giles departs as a regular character; he would now return only as a special guest.
