Kassie
I have long been a fan of Kassie's writing. She's just phenomenal. "Regrets" is a beautifully nuanced Cordelia story, where nothing is told outright, and everything is hinted at. Kassie explores a dark moment in Cordy's life, and shows how the littlest things can send you into a dark maelstrom of emotion. I think this is my favorite story that she's written, and let me say that she's not written one that I don't like.
And you know what? Kassie did it again. The short summary: Fred babbles. Angel broods. A better summary: Angel is Fred-sitting, trying to work out what has happened, what will happen, and what the hell he's supposed to do about it. It's excellent.
