Plot Season seven deals with the Potential Slayers, normal girls around the world who are candidates to succeed the Slayer upon her death. It is revealed that Buffy's resurrection caused an instability which allows The First Evil, a spiritual entity that Buffy encountered in the third season, to begin tipping the balance between good and evil. It has inactive Potential Slayers hunted and killed by Caleb, a sinister and misogynistic preacher turned serial killer, who heads a cult called Bringers, who worship The First as a god. Inside the Hellmouth it raises an army of Turok-Han, an ancient and powerful sub species of vampire. Caleb later destroys the Watchers' Council's headquarters in London, killing many Watchers, including Quentin Travers. Dawn begins her sophomore year at high school. Buffy gets a job at the rebuilt Sunnydale High, where she meets the new principal, Robin Wood, a vampire hunter and the son of deceased Slayer, Nikki Wood, who was killed by Spike in New York City many years ago. Buffy also reunites with Willow, who still is working through her emotional rampage in the previous season, and Spike, who earned his soul back but is temporarily driven mad by regret. Willow begins to heal emotionally from Tara's death and finds solace with a Potential Slayer named Kennedy. They immediately start dating before Kennedy can fully understand Willow. Their relationship is strained when Willow drains a significant portion of her life force to reopen a portal for Buffy, but they soon reconcile. Andrew Wells and Jonathan Levinson leave Mexico and return to Sunnydale after The First convinces Andrew to help open the Seal of Danzalthar, which results in the death of Jonathan. Andrew is captured by the Scoobies, who show resentment toward him, but he becomes a committed ally after The First takes Jonathan's form and tries to convince him to kill all the Potentials in the house. Andrew refuses, insisting he's good now, later admitting his guilt about how cruel his betrayal of Jonathan was and disclosing that he does not believe he will survive the forthcoming battle.
