The credits read "Eliza Dushku as Buffy", instead of "as Faith", reflecting the fact she is playing Buffy in Faith's body for the majority of the episode.
Faith (in Buffy's body) becomes the first person to recognize Willow and Tara's romantic relationship. This makes her the only character, apart from Spike, to recognize it without being told, Spike figures it out himself in The Yoko Factor (2000). Willow will only tell Buffy about Tara in New Moon Rising (2000), and Xander and Giles in The Yoko Factor (2000).
Buffy's hairstyle changes after Faith inhabits her body from straight to loose curls (crimped), and Faith's hairstyle changes from loose curls (crimped) to straight, in which no other character notices, (especially Joyce).
Buffy (in Faith's body) stakes the vampire Boone from behind when it is attacking Faith (in Buffy's body), revealing her standing there when it dusts. This scene echoes Faith staking Mr. Trick in Consequences (1999).
