Riddle continued his habit of ambushing Harry and demanding answers, only now Harry was obliged to give them. Self-involved as Riddle was, most questions pertained to Voldemort: "You said he was insane. What caused this insanity and when did it begin to manifest?" and "Which of Voldemort’s aims were most tenable to the general populace of Wizarding Britain, and which most objectionable?" Sometimes he branched out, though most queries still related to him in some way. "You said Dumbledore defeats Grindelwald. Does he kill him? A prison, you say? What were the security measures?"
