After Buffy is resurrected at the beginning of season 6, she is despondent and detached from her friends. During this time, her relationship to Spike deepens and she is able to talk to him about things she feels she cannot share with the Scooby Gang. She gets drunk with Spike, and calls him "a neutered vampire who cheats at kitten poker." After a demon's spell makes them express their emotions in song, and Buffy sings "I want the fire back", Buffy and Spike begin a physical relationship, consummated two episodes later. The relationship is frequently violent, with Buffy most often initiating both the violence and the sex between them; the violence is made all the easier when Spike finds that (as a side effect of Willow's resurrection spell) his chip now does not stop him from harming Buffy. Buffy threatens to kill Spike if he ever tells anyone about their relationship. Both are unsatisfied; Buffy is ashamed of her dark desires, while Spike obsessively craves the love, trust, and affection that she is unwilling to give. In "As You Were", Buffy tells Spike she is using him and ends their relationship. Believing he still has a chance with Buffy after seeing her reactions of jealousy and hurt when he has a drunk sexual encounter with Anya, Spike corners her and makes aggressive sexual advances. When she refuses him, he grows desperate and unsuccessfully tries to rape her. He is at once horrified by his own actions and intentions, while also somewhat remiss that he did not go through with the rape, since he is still essentially a demon and has had no problem committing such acts in the past. This is seen in his reactions to reliving the memory of the event while discussing his subsequent mood with Clem, who has come by with hot wings to hang out. Spike heads to a remote area of Africa, where he seeks out a legendary demon shaman and undergoes the Demon Trials, a series of grueling physical challenges. Proving his worthiness by surviving the trials, Spike earns his soul back.
