At the Summers's home after dinner, Buffy confesses to Giles that she's worried about her ability to love. Giles suggests he and Buffy go to a sacred location in the desert so that she can undergo a vision quest. When they arrive, Giles performs a ritual to create Buffy's guide. A mountain lion appears and directs Buffy into an open desert that reminds her of her dream from "Restless."
Glory orders her minions to watch the Slayer and see who is new and special in her life, as that person is likely to be the Key. That night, one of the minions watches the group through a window; Dawn secretly takes Anya's earrings from a table.
Spike receives his Buffybot from Warren, commissioned in "I Was Made to Love You". Spike and his Buffybot pretend to fight, which inevitably leads to sex. While Spike is sleeping it off, the Buffybot heads out to patrol for vampires. She runs into Xander and Anya in a graveyard and successfully masquerades as Buffy. Later, Xander and Anya oversee Spike and the Buffybot having sex in the cemetery, and shocked, Xander goes to confront them. However, Glory's minions assume Spike is the Key, and knock Xander unconscious and take Spike. Glory is upset when she sees Spike, as she knows a vampire cannot be the Key. Nevertheless, she decides to torture him in hopes that he knows where the Key is.
Buffy wakes to find the First Slayer on the opposite side of a large fire. The First Slayer advises Buffy that love is at the center of all Slayers and that love will bring Buffy to her gift. When Buffy asks "What gift?", the First Slayer tells her death is her gift.
Worried about Spike, the Buffybot leaves Xander unconscious at the crypt and goes to the Summers' residence for help. Willow sternly talks to the Buffybot (whom she mistakes for Buffy) about her sexual relationship with Spike, until realizing Glory has a captive who knows that Dawn is the Key, and the gang prepares to kill Spike before he can reveal Dawn's secret. When the Buffybot goes upstairs to change, the real Buffy enters, which clears up all the confusion. Meanwhile, Glory is brutally torturing Spike, who refuses to tell her the Key's location and subjects Glory to a symphony of verbal abuse. Spike manages to escape through the elevator, where he finds the Scooby Gang waiting, and they fight off Glory's minions and leave the mansion.
At the Magic Box, Willow examines the Buffybot. Spike rests in his crypt, beaten and bloody. Pretending to be the robot, Buffy enters the crypt and curiously asks Spike why he didn't give Glory the information she wanted. Spike says he could never hurt the real Buffy, and she kisses him. Spike pulls back as he realizes it is actually Buffy; she says she'll never forget what he did for her and Dawn.
