The Slytherin response to thirty-five Muggle-borns leaving Hogwarts had been to bully a half-blood Hufflepuff firstie, two days ago. Yesterday three Slytherins, of different years, had been attacked as they had stepped out of the Slytherin common room and into the dungeons. The attackers were rumoured to be Disillusioned sixth- and seventh-year half-bloods, all wizard-raised. All three Slytherins had been cursed badly enough to be sent to the hospital wing—and also had been Obliviated, so that they could not name their attackers.
