"He’s out of his mind," said Proctor Bulstrode, another Slytherin boy in Potter’s year, "It’s a nightmare sharing a room with him. He climbs all over the furniture, claiming he’s "solving mysteries,’ and he sneaks in Gryffindor boys when he thinks all of us are out. Especially Conifer, he loves to sneak Ricky Conifer into the dorm." Ricky Conifer, the mentioned Gryffindor, is a muggle-born wizard in the same year as Potter. They’ve allegedly become quite close.
