(4th year)

Harry woke up in a cold sweat. He remembered that day in his 2nd year after he ran into Dumbledore's office crying that he almost killed Dean Thomas without magic. That he was just so hungry because he hadn't eaten all day. Then out of nowhere, he just lunged at Dean, and tried to bite him.
