Hazel Potter was never alone; she was fiercely backed by her four adoptive brothers-Ryan, Danny, Spencer, and Tony-and the powerful teams standing right behind them. But when the crushing weight of the Great Hall causes a sudden, severe classification drop, Hazel is completely overwhelmed, regressing instantly into a helpless, non-verbal baby headspace. Before the stunned school can react, Severus Snape and the Slytherins form an impenetrable defensive wall, lifting the fragile, crying infant-minded girl and bringing her straight to Ryan. With Hazel safe and cradled in her oldest brother's arms, the four boys and their respective teams mobilize alongside the Slytherins, creating an absolute fortress around their baby sister that no one in Hogwarts dares to cross.
