After high school, Dushku returned to acting with the role of Faith, a Slayer much more troubled than the main character Buffy. At first, her character was only going to be used for five episodes but became so popular that Joss Whedon decided to use her for more of the story. She stayed on for the rest of the third season and returned for a two-part appearance in season four. She was then used as part of the first season of the "Buffy" spinoff series "Angel". Faith returned as a heroine in several other episodes of "Angel" and in the last five episodes of "Buffy".
