Faith wakes up from her coma and pretty instantly wreaks havoc on Buffy's life, using a device left by Mayor Wilkins to switch bodies with the other Slayer. Sarah Michelle Gellar is perfect as Faith, and Eliza Dushku is equally adept at playing Buffy. It's a total mindfuck, with serious consequences for the characters.
