When Willow threatens to tell some embarrassing old stories about Xander, the gang provisionally accept her claim. As Willow and Kennedy attempt to break the spell, Robson, a Watcher, calls Buffy's house from England and reports that Giles may have been killed by a Bringer who had attacked him in London several weeks before. The Scoobies become alarmed when none of them can remember seeing Giles touch or carry anything since his return; no one has hugged him, and he is not driving the car to the desert. Xander, Anya, Dawn, and Andrew all go to the desert to find Giles and, in the case of danger, stop him from hurting the Potentials. Giles is tackled to the ground by the others, who are all pleased to find that he has a solid form and thus is not the First – or dead. Willow and Kennedy meet with the Wiccan group at the UC Sunnydale, which now includes Amy. Willow runs away as she realizes she is starting to behave like Warren. Kennedy tries to follow, but Willow puts up a magical barrier to keep her away. After the meeting, Kennedy returns to the lecture hall to find Amy packing up as the rest of the group has left. Amy comments on Kennedy's concern for Willow, and draws Kennedy's suspicion when she mentions that Kennedy is a Potential, a fact that neither Kennedy or Willow had mentioned. Willow, increasingly dominated by the Warren persona, goes to buy a gun of the same model that killed Tara and wounded Buffy. Kennedy confronts Amy, accusing her of causing the "Warren" problem. Amy reveals that she put a hex on Willow, whose effect is determined by the victim's subconscious. She did it because Willow murdered a man and remained beloved – crowning Amy's envy of Willow's relatively easy successes in magic. Amy then teleports Kennedy to the backyard of Buffy's house, where Willow starts to reenact Warren's attack on Buffy that resulted in Tara's death, but Kennedy talks her down. Willow tearfully explains that when Kennedy kissed her she let go of Tara's memory for a moment, making her truly dead. Then Kennedy kisses Willow again, breaking the spell and restoring Willow to normal.
