Malfoy nodded his head, because that exactly how he felt. He didn’t know how she did it, but Hermione Granger had just figured out what was wrong with him. In his mind, he was starting to fear his own magic. But she had taken the time to think his problem through. Honestly he hadn’t even noticed when those short outbursts of magic began. But as Hermione started to talk, he traced it back to the time when Dumbledore had died. To be specific, it was from the moment he dropped his wand, unable to go through with his mission. If she was right, that was the moment his magic had started to change. Even till this day, he didn’t know what made him not kill Dumbledore. But everything made more sense, the more she explained.
