Faith and Buffy switch bodies, and Buffy, trapped in Faith's body, is kept in police custody. However, in the way to the precinct, the retrieval team of the Watchers' Council provokes an accident with an armored truck and captures her from the police car. Faith uses to freedom of Buffy's body to enjoy life, flirting with many guys in the Bronze and buying a ticket to overseas. When Willow introduces Tara to Buffy, she feels an evil aura in her soul. Willow and Tara decides to make a dangerous astral projection to the Nether Realm that exists beyond the physical world to find the truth. Adam trains three vampires against fear, and they kidnap and threaten churchgoers of a church. Faith listens to the news in the airport and goes to the church, where Buffy, Riley and the Scooby group are facing the monsters.
The sequel of "This Year's Girl" is a great episode of Buffy. The story develops in many directions, all of them very attractive, with participation of practically all the cast. It is clear that the permanence of Faith in Buffy's body changed her behavior, and she was able to sacrifice her secure travel to risk her life in the church. I liked this episode a lot, which had a rip-off in "Transference" in the Fourth Season of "Smallville", when Lionel Luthor swaps bodies with Clark Kent. My vote is nine.
Title (Brazil): "Quem é Você?" ("Who Are You?")
