Giles knocks on Buffy's front door, and Willow lets him in. She hands him the book with the spell of un-inviting vampires and tells him the spell went fine until "Angel showed up and told Buffy's mom that he and Buffy had -- " She pauses, "Well, you know, that they had -- you know. You do know, right?" Giles, who hasn't really been paying attention, says he does know, and Willow is happy because, "being a librarian and all," she was afraid he didn't. They stare at each other and bob nervously, and Willow finally says she'll tell Buffy Giles was there. He suggests intervening in the conversation between Buffy and her mom, but when Willow asks what he would say, he can't think of anything. Willow opens the door, and Giles leaves.
Buffy and her mom are having a talk in Buffy's room. As her mom paces, arms crossed, Buffy offers a lame explanation that the chanting and herbs were because Angel is "superstitious." "Was he the first?" asks Joyce, and then immediately takes it back, saying she doesn't want to know. Buffy replies that Angels was the first and "the only." Joyce points out that Angel is "obviously not very stable" and then twists the knife: "I just thought you would show more judgment." Ouch! Buffy looks hurt but merely explains that Angel "wasn't like this before." Joyce asks if she loves him, and Buffy replies that she did. When Joyce starts to inquire if Buffy had safe sex, Buffy snaps at her, but Joyce snaps back, saying that Buffy can't evade this one. The scene is starting to get to Buffy, and you can see the tears welling as she admits, "I made a mistake," and her mother can't even guess at the proportions of that mistake, can she? Joyce says, "Don't expect me to ever stop caring about you, because it's never gonna happen. I love you more than anything in the world," and then sits next to Buffy, finishing, "That would be your cue to, uh, roll your eyes and tell me I'm grossing you out." Buffy replies that she isn't, and that concludes the talk.
