In "Buffy the Vampire Slayer" season three, Faith arrives in Sunnydale, having been activated as the Slayer by the death of Kendra (Bianca Lawson) in the episode "Becoming, Part One" (who was activated by Buffy's temporary death in the first season). Coming from a traumatic and abusive background, Faith tries to fit in with Buffy (Sarah Michelle Gellar) and her friends, but becomes increasingly isolated and bitter as the season progresses. A major turning point for the character occurs in the mid-season episode "Bad Girls"; while trying to show Buffy the fun side of slaying, Faith accidentally kills Deputy Mayor Allan Finch (Jack Plotnick), a human being whom she mistakes for a vampire. Feeling more alienated than ever, she betrays the Scooby Gang and allies herself with the villainous Mayor of Sunnydale (Harry Groener), eventually forming a sincere father-daughter relationship with him. After Faith tries to murder Buffy's vampire lover Angel (David Boreanaz) under the Mayor's orders, the two Slayers finally battle it out in the season finale, a confrontation which leaves Faith alive but comatose.
