Did Harry do something wrong? Had she become disgusted by his scars, by his missing eye? Did she realise how dangerous it would be to be around him, that she might end up dead like Cedric? Or had she seen how dangerous he could be, when he lost his temper and let that raging beast out? Since the graveyard, when Harry went berserk in trying to kill Wormtail and Voldemort despite his grievous wounds, he hadn’t felt the same, nor had he acted as he did before the Third Task. Had Cho sensed that change within him and didn’t want to risk getting hurt?
