Harry Potter and the Time He Wasn't Actually Harry Potter

..wait, what? Harry Potter not himself? Well, when you factor in a skewed ritual done by a dead person, an evil wizard, and a time-traveling baby, it starts to make a little more sense. Maybe not to the students of Hogwarts, though, who are all a bit miffed that Harry Potter has somehow managed to enter himself into the Triwizard Tournament, despite being 1774 years in the past.
