Buffy has to withdraw from college to take care of Dawn, who it turns out has been skipping school. Dawn's school principal warns Buffy that she might not be found fit to be Dawn's legal guardian, so Buffy resolves to be more like a mother than a sister now. Willow and Tara have their first fight as Tara admits she's frightened by how powerful Willow is becoming.
Meanwhile, Willow feels that Tara doubts Willow's love for her and storms out. Glory, after discovering that Tara is the newest member of the Scooby Gang, believes her to be the Key. She finds Tara alone but, realizing that Tara isn't the Key after crushing her hand and tasting the blood, demands to know who is. Tara refuses to talk, so Glory drains her mind instead. Giles, Anya and Willow capture one of Glory's minions, who reveals that Glory thinks Tara is the Key.
However, Willow rushes off to save her, but is too late. After taking Tara to the hospital, Willow goes after Glory alone and although she is able to hurt the god briefly with some dark magic, Glory soon overpowers her. Buffy, realizing what Willow was going to do, turns up at Glory's apartment and helps Willow escape. Back at Willow and Tara's dorm room, the witches, Buffy and Dawn are having a snack when Glory appears, tearing down the dorm wall. When Tara, out of her mind, looks at Dawn and talks of the pure green energy she sees, Glory smiles, finally realizing who the Key is.
