Context: ‘Who Are You’ is the the sixteenth episode of season 4 of Buffy the Vampire Slayer. It’s the episode where Buffy and Faith switch bodies (well, the switch happens at the end of the previous episode, but this is the episode where we see how it plays out). Faith is a wanted criminal, so Buffy-in-Faith’s-body is first arrested by the police, and then intercepted by muscle working for the Watcher’s Council. In the time it takes her to escape from her incarceration and return to Sunnydale to reclaim her body, Buffy has received a taste of how those who know Faith feel justified in treating her: she has been called trash, and her/Faith’s face has been spat at. Meanwhile, Faith-in-Buffy’s-body has received her own novel taste of what it is to be treated with love (both maternal and romantic), gratitude and respect. The two Slayers come face to face with each other/themselves once more when both independently learn that vampires are holding a congregation hostage in a church, and go there on a rescue mission. Once the vampires have been dispatched, Buffy and Faith fight it out on the church’s altar. Faith-in-Buffy’s-body gains the upper hand, and straddles Buffy-in-Faith’s-body while she directs blow after self-loathing blow and insult after self-loathing insult at her own face. What she does not know is that Willow and Tara have conjured Buffy a doohickey that will reverse the body swap. Buffy interrupts Faith’s onslaught by clasping her hand (in a gesture with the appearance – appropriately, given the location and aspects of the pair’s relationship – of communion). There is a glow, a shudder, and a rushing sound effect to confirm that the reversal has worked.
