"It fits," Harry said, firmly. "Since I saw him in the bloody Leaky Cauldron when we went for my school supplies my magick has felt off. On the first night when we met eyes? Pain shot straight through my scar. He was in the dungeons before the troll attack—the man is afraid of his own shadow, Ev. Why was he in the dungeons alone? At all for that matter. He was limping after the troll attack, Malfoy saw the wound —it looked like a large dog bite. He told Filch to tell him if anyone was creeping around in the restricted section of the library. Even his stutter's fake. We know what the dog is guarding, Evan. I think he’s going to try stealing it."
