    When he was small, Hill was a famous bad boy.

    His father introduced Hill to his stepmother as he said, “Dear, I hope you notice in the entire shire this is the worst boy, who has made me have no other way. Maybe before tomorrow morning he will throw a stone at you, or do a bad thing you will never imagine.”
