Rebellion

First-year Hogwarts student Sirius Black was sure he'd break the family tradition of being sorted into Slytherin, yet here he was, despite everything. But when he sees the way the small, greasy-haired half-blood is being treated, he realises that perhaps there's another way he can rebel against his family and that perhaps there are other ways to rebel.
