I had a dream where someone released a version of Harry Potter where everything happened the same except the main three characters were different and they reacted vaguely differently to the events of the books/movies. I can’t remember Harry and Ron’s counterpart names but Hermione was Susan, and she wasn’t a very strong swimmer. Draco shaved off a piece of “Harry’s” hair during a Quidditch match to distract him and throw him off his game.
