Riddle was always on his best behaviour. Harry had expected to see wild displays of bullying, violence, and aggression, but he’d found the opposite. Riddle never relaxed his flawless decorum. Even in the common room his manners were polished and perfect, and his uniform – which he wore near constantly, since he seemed to only have two casual robes – was always neatly pressed. For Merlin’s sake, he even sat in the armchairs like he was on a throne, his perfect posture the very picture of what Beatrice had tried to beat into his spine over the summer.
