DID You Hear The Rabbit Cry?

It seems that Harry has Dissociative Identity Disorder (Multiple Personality Disorder). To him, this is nothing new. He's known of his alters for as long as he can remember. Magic, however, is a different story entirely. When he finds himself sorted into Slytherin, he learns that the choices he must make are more important than he ever imagined. ((Currently in Book 3))
