Riddle’s mask of faux modesty in the aftermath of his admittedly impressive performance was near impeccable, but Harry could see through it to the arrogant psychopath underneath. Not that Riddle was trying as hard as he had previously to hide it from Harry.

He’d seen none of the anger and aggression he knew Riddle was capable of, Riddle keeping that violence tucked under yet another layer.
