The Visitor
This is stunning. I insistently overlooked the clues. Somehow I kept hoping that Snape's policy of non-interference was his way of being honorable (not encouraging adultery or divorce), and that Harry would be man enough to decide on his own to spend the rest of his life at Hogwarts...living happily ever after with Snape, of course. I'm sure that's sort of what you intended readers to want. You did such a great job with the fic that I really don't mind the fact that you killed off our heroes. I can't imagine higher praise than that.
