condition and initially hopes the Hellmouth's energy can help restore her strength. He reunites with Angel and seems genuinely pleased to see him, but is disgusted to find that Angel has a soul (whether or not Spike in fact knew that Angel's acquisition of a soul is why he left the group nearly a century before has never been made clear) and is in love with the current Slayer, Buffy Summers. When Angel loses his soul and rejoins Spike and Dru, Spike's initial celebration soon turns to resentment when Angelus starts pursuing Drusilla as a lover and taunting him. Spike decides to ally himself with Buffy against Angelus; as he explains to Buffy, in addition to wanting Drusilla back, he also wants to "save the world": Spike reappears in the season 3 episode "Lovers Walk", in a drunken depression after Drusilla, offended by his alliance with Buffy, dumps him for a Chaos demon.

Spike goes to Los Angeles, and hires a vampire named Marcus to torture Angel in order to get the ring, but Marcus takes the ring himself and Angel finally destroys it.
