Episode Guide: Season 4 
Below are all the episodes Faith appeared in for Season 4.
4.14 This Year’s Girl
It's been eight months since Faith's dive of roof and into a coma. When she wakes, she's firstly, disorientated and secondly, extremely angry. As Buffy says: "Hi jinx ensue." when Faith finds that no-one cared enough to visit, the Mayor is dead and the love of Buffy's life, Angel, the guy she was willing to kill Faith for, is no longer in the picture. Hell hath no fury like a Slayer scorned!4.15 Who Are You?
This is part two of a wonderful Buffy double however- note: For simplicity's sake, Buffy is Faith and Faith is Buffy. OR ...as in notes in the credits...Eliza is Buffy and SMG is Faith. Wonderfully played on both parts. Eliza has Buffy's quirks 'down'...while Sarah has (although not quite as well as Eliza) managed to tap into Faith's vulnerability...specifically the love scene with Riley.
