I went from liking Faith (her whole badass Slayerness was such a great contrast to Buffy's...who, granted, went against the Council's grain a lot but still took her calling seriously), to loving Faith (she became a good friend to the Scoobies and Buffy..the scene where she calls Scott out on having a rash in front of his Homecoming date stands out in particular), to hating Faith (the whole going evil bit, although it made for some pretty awesome TV, and I DID love the Mayor a whole lot). And I thought I would dislike Faith forever, until she came back in Season 4. At the end of this dual-episode, when she is pummeling herself for all she's done and you can just FEEL through the TV screen how much she hates herself, and how much baggage she's carrying, and just how much she's hurting..well, it made me love her again. She made a great foil for Buffy, but she was also a complex, multi-layered character all on her own. When she comes back in S7, she has matured and grown in such a wonderful way. I just regret that we weren't able to see more of the recovered, better Faith in the later seasons.
