YMMV / Buffy the Vampire Slayer S3E7 "Revelations"

• Magnificent Bitch: Gwendolyn Post presents herself as a well-meaning Watcher for Faith Lehane, while in truth she is actually a dark witch seeking the Glove of Myneghon for herself. Quickly feeding into Giles' and Faith's inferiority complexes in different ways, she pretends to be a friend of Faith's, informing her of a meeting the Gang had without her so as to further split them apart from each other. After manipulating Giles into giving up the information on the Glove's whereabouts, Post knocks Giles out before meeting with Angel, claiming to be there on his behalf. When Angel sees through the ruse and attacks her, she manipulates Faith into fighting on her behalf; when Buffy attempts to diffuse the situation, Post manages to manipulate Faith into fighting her as well, turning the two Slayers against each other. While she successfully gets her hands on the Glove for herself, Post's actions also result in Faith's permanent separation from the team, with neither Slayer ever quite recovering from the ease in which she pit them against each other.
• Retroactive Recognition: Gwendolyn Post is played by Serena Scott Thomas, who would become more famous a year later for portraying Dr. Molly Warmflash in the James Bond film The World Is Not Enough.
