Coriolanus doesn't notice how much he snorts with laughter when you pick up on his inner monologue, calling Arachne a show-off and Professor Highbottom someone who should be isolated from decent capitol society. He immediately blushes a little and covers his mouth with his handkerchief and frowns at you. You're in the canteen now, eating after all, and you're going to make him look ridiculous.
