I had so much fun reading this! I'm tickled by the idea that Snape would agree to manifest himself in the form of Kuki to watch over Harry. But then again, where Lily was involved, I'm sure he would promise anything *g*
I really like the exploration of the "what if" scenario if Voldemort was confined to a closet (that in and of itself was brilliant). Besides all the little references to outside stories and movies, you also peppered the story with HP references. Loved the bit with Harry giving Sirius the two-way mirror :)
