Thanks for clearing up the scene about Spike and Faith, it would actually be nice to see see what their feelings are about the situation cos I'm pretty sure that Spike would be pissed about what has happened to Willow and Tara. And knowng Faith's previous relatons with the Scoobies she may be feeling some guilt and anger over what is happening and her lack of being able to deal with it.
And again Don't worry about not being able to finish the story sooner, would much rather read a story that takes time to be written but is written well like yours than one that has lots of updates but is written shoddily and I have read a couple of those in my time
