1 i do love your Spuffy approach to the issues at hand. 2.I don't think she actually slept with anyone. I think as you do, that they're messing with shippers. At worst she probably fooled around with some random guy and pucked all over someone else. Either way it's kinda awful when you have a "black hole" after partying an her reactions are more than understandable. Or they would if I didn't feel like it's all a big joke for Joss et al.
On the spuffy front I only feel optimistic when I read wonderful fic like yours, but the comics still haven't addressed anything.
