Thank you! I wanted to get Snape completely outside the context in which we'd seen him previously and using time-travel seemed like something that had already been done quite a bit -- plus I liked the idea of him and Harry as practically the same biological age for a change. I have notes on lots more involving the other characters but a lot of it seemed extraneous to a story about Harry and Snape, especially the very dark backstory, but I might come back to that!
