Hey everyone. Though I'm new to posting on this thread (Not the Board itself), I find many of the ideas very interesting, much more inspiring than the (ugh) real S6, and am looking so forward to seeing the complete stories that I don't have much to add. Except for what to do about Amy after Episode 10.
Perhaps after Willow sticks her hand into Amy-Rat's skull to extract the magic to heal Tara, the frightened and disoriented Amy-Rat uses the ensuing confusion to flee the Summers' house and disappear for the rest of this season, as Amy's presence doesn't seem to be required for the main arc.
Then, midway through the Kitten Rewrite of Season Seven, Amy returns. I propose that for many months after her escape, Amy-Rat wandered the streets thinking and behaving like a common rat as a result of the brain damage caused by Willow's spell, and remained that way until something or someone (not Willow) turns Amy back into a human being. That person then gradually restores Amy's mind back to her former personality - for reasons yet unknown - which leads to a tense confrontation between Amy, Willow & Tara over the events of S6.
At this point, I don't have all the details figured out. But since this would only be a three-part arc for S7, I think it'll be OK to hold off on it until S6 is completed. Until then, I look forward to seeing the final results.
