Oh, this is amazing. I've had chills running all through my body reading this. It's extremely intriguing and it works despite how weird the assumptions are. It's like the Ringu of HP. Great characterizations of everyone. (Especially Tonks, and Luna, and Merope). I love what you did with what is just a streak of coincidences to string them together. It's funny and freaky, and utterly wicked.
