Rather than allowing Harry to stay at Diagon Alley after he blew up Aunt Marge, the Ministry sends Harry back to the Dursleys. Harry returns to school after a terrible summer, to find that he's not the only one with this kind of secret. A student has been killed by his family. New screening measures are put into place by the Ministry: Every student must be given a medical exam and interview to look for child abuse. With Dumbledore facing an inquiry, Snape is entrusted with the task of making sure EVERYONE receives one.
