Good Slayer/Bad Slayer
“Bad Girls” is the first episode where we meet Faith, the second slayer. She is the opposite of Buffy; she loves to slay, she dresses in dark and bold clothing, she lives on her own, and she focuses only on her job as a slayer. I think the fact that they are opposites is important because it shows two extremes of super heroines. They fight incredibly well as a team and help each other when in need. Throughout the episode we see Faith corrupt Buffy and turn her into a “bad girl” (hence the title of the episode). She skips her chemistry test, hurts Willow’s feelings, dances provocatively with men at Bronze, steals weapons, and ultimately crashes a police car after having been arrested.
It is in this episode that we see Buffy, the strong, good-willed slayer, turn into a risqué bad ass. However, the ending scene really showed the true difference between Buffy and Faith: their morals. When Faith accidentally kills a man, mistaking him for a vampire, she feels no remorse and tells Buffy she does not care that she killed a human. Buffy on the other hand, feels terribly and continues to confront Faith about the killing.
We see Buffy transform throughout this episode, but she shows her true colors in the end when she feels guilt for the death of a human.
