My favorite fic of yours that always comes to mind is "Prism," because one of my biggest Spuffy kinks is reading Spuffy from others' POV, and you capture the personalities of such often reviled characters so vividly. In terms of actual details, I think it's a toss-up between Buffy and Spike's conversation about him never having bitten her (such a tense moment that requires them to be honest and actually *talk*, rather than just let their looks/touches speak for them) and the end with Faith. I adore her conversation with Buffy, and the bittersweetness of the last few lines is just...gah. Emotionally draining and poignant and perfect. I love when fics don't pull the hard punches, and much as I don't like to see Buffy in pain, at that point in time her sadness/pain/regret is completely realistic and necessary. I appreciate her recognition that Faith was right and that she left things unsaid until it was too late.
