Another night at the Bronze, and Xander and Willow attempt to draw their significant others' attention away from their increasingly guilty behavior by bringing up Buffy's mysteriously distracted behavior of late. Just as they convince themselves it's a new boyfriend in Buffy's life, Buffy herself arrives, but assures them her "date" for the night is only Faith, going out to the graveyard to do some tag-team Slaying. Their performance is called sloppy by an imperious British woman who emerges from the shadows and introduces herself as Gwendolyn Post, Faith's new Watcher. At the library, Mrs. Post has two more bits of distressing news: in addition to being Faith's Watcher, the Watchers' Council also sent her to observe and report on Giles' performance as a Watcher, due to fears he has become "too American;" and a demon named Lagos is coming to Sunnydale in search of a mysterious and dangerous artifact called the Glove of Mynnegon. The next day, Buffy learns T'ai Chi from Angel, but the lesson threatens to get more intimate than planned. Buffy anxiously excuses herself, telling Angel about the hunt for Lagos. The name seems to spark some recognition in Angel. Later, a frustrated Giles takes out his frustration on Willow and Xander, whose mutual commiseration leads to another passionate kiss. They break apart guiltily when Giles tells them he's found that the Glove is hidden in the von Hauptmann family crypt. A guilty Xander offers to go to the Restfield Cemetary, site of the von Hauptmann crypt, to tell Buffy. Meanwhile, Faith and Buffy's Lagos hunt is unsuccessful, and Faith suggests that Buffy go home while she makes one last check of the nearby Shady Hill Cemetary. There Faith hits the jackpot, finding a burly demon rooting through a sarcophagus. She just gets tossed around like a rag-doll for her troubles, though, and Lagos obviously doesn't find what he's looking for and stomps off. Xander has a different kind of success, for when he goes to the Restfield Cemetary he sees Angel emerging from the von Hauptmann crypt carrying a wrapped object. Tailing the vampire back to the mansion, he sees Angel and Buffy engaged in a passionate kiss. The two break off their kiss, upset, but Angel stops Buffy from leaving by showing her that he has the Glove of Mynnegon. Meanwhile, at Giles' apartment, Mrs. Post is expressing her disdain for Giles' methods as a Watcher. Just as he insists he's in complete control of Buffy, Xander bursts through the door, and as Mrs. Post smugly drinks her tea, Giles and Xander converse in secret. Buffy arrives at the library the next day full of the good news about the Glove, but all her friends look upset. Giles tells her they know that Angel is alive, and a confrontation ensues. Insisting that Angel is better, she apologizes for not telling them, but her friends are scared of what Angel may do, and Xander is especially vehement in his arguing with the Slayer. Finally, Giles stops the argument and sends them all back to class. But when Buffy attempts to thank him, he coldly reminds her of how Angel tortured him, and tells her she has no respect for him. Meanwhile, Mrs. Post visits Faith in her shabby motel room, and while explaining her intention to be a hard taskmistress for Faith's own wellbeing, she lets slip the fact of Giles' secret meeting with Xander. That night Faith finds Xander angrily shooting pool at the Bronze. When she confronts him about keeping Slayer-related secrets from her, he tells her about Angel.Fearing what Angel might do with the Glove, she resolves to kill him, and Xander asks tocome along. Back at Giles' office, Giles tells Mrs. Post about Angel having the Glove, and says he's found that the Glove can be destroyed by being immolated in living flame. Mrs. Post then coldly clubs Giles into unconsciousness. As Buffy and Willow wait for Lagos at the von Hauptmann crypt, Buffy confides that she's actually relieved her secret's out. Emboldened by Buffy, Willow is about to share her own secret when Lagos arrives. While Willow watches, Buffy fights Lagos and, grabbing the axe off the demon's back, beheads him. The fight over, Willow backs out of sharing her secret. The two girls head back to the library, where they find Giles on a stretcher. Xander starts to blame Angel, but Buffy doesn't believe it. Xander tells her Faith does believe it and has gone to kill Angel, and an angry Buffy runs out to catch Faith, ordering Willow and Xander to find out how to destroy the Glove. Mrs. Post arrives at the mansion, where Angel is doing the living flame ritual himself. Telling him that if he does the ritual incorrectly it could make the Glove more powerful, she convinces Angel to reveal the whereabouts of the Glove, then knocks him out with a shovel. She didn't count on him being a vampire, though, and he gets right back up, in full vampire-face, and attacks her. Just then, Faith arrives and, seeing a vampire attacking her Watcher, draws the obvious conclusion. She attacks Angel viciously, and is just about to stake him when Buffy arrives and stops her. She tries to talk Faith out of it, but Mrs. Post convinces Faith that Buffy is blinded by love, and Faith attacks Buffy. The two Slayers go at it tooth and nail, and the fight breaks through the doors and into the courtyard. Willow and Xander show up with the living flame catalyst, and Xander tries to break up the Slayer fight, only to get literally thrown aside. Willow helps Mrs. Post get the Glove of Mynnegon, then gets knocked out as Mrs. Post puts on the Glove. As Mrs. Post recites an incantation, thunder peals and the two Slayers stop fighting. Faith asks her Watcher what's going on. "Faith, a word of advice: you're an idiot," Mrs. Post says and hurls lightning from the Glove at the two Slayers, who barely manage to duck aside. Angel comes to and saves a groggy Willow from another Glove blast. As Faith draws Mrs. Post's fire, Buffy picks up a shard of broken glass from the shattered courtyard doors, and hurls it, severing Mrs. Post's Glove-wearing arm. Mrs. Post is consumed by lighting, and the Glove releases the amputated arm. The next day, having disposed of the Glove, the gang is still leery of Angel's reappearance, but they all (except Cordelia) trust Buffy and are willing to see what happens. Buffy goes to Faith's apartment and tries to convince Faith that what happened wasn't her fault. "You can trust me," says Buffy. "I'm on your side." Faith doesn't seem to believe her, and as Buffy sadly leaves, Faith says, "I'm on my side. That's enough."
