First of all, I would like to congratulate you on writing this all in second person. It is definitely the hardest of the points of view to write. First person is the easiest and I find that most of the stories that are in first person are either not as well written as one in another point of view or tend to be more a personal reflection of the author's character than the characters the author is trying to portray. But you did well here. So congrats! I do have to say though that I was a little confused at certain points as to who was talking and what was going on, but then I read slower and picked up the natural yin and yang of the back and forth between Buffy and Faith so that wasn't an issue. Just be cautious of it if you have a character speak twice in a row to make sure we know who is talking. I gleamed from the piece that Faith had died, not Buffy? Is that correct? I like that twist on the idea because it changes Buffy's perspective. Write more please. :)
