Have you seen "Welcome to Hogwarts1949"? This article is written in imitation of that, and it is not one ten thousandth of its sense of humor, but we still insist on writing it, for the sake of our love. .

When he remembered it, Dumbledore told him that history cannot be modified, so we don't have to worry about Riddle remembering us...
