You had gone to a criminal meet-up in Gotham (you can choose whether it's as a villain, an undercover hero, an undercover cop, by accident, etc.), one of the bigger ones where really only the big names were. The Penguin, The Joker, Black Mask, Bane, and Rupert Thorne. Mr. Thorne is wider than the others and a respectable height of around 6ft1. He's more straightforward and stereotypical than the other bosses. The slicked back hair, the charm, the aggressive discipline, the 'take CARE of him' mentality. He runs a drug cartel and several other smuggling schemes, he's got money in his pocket and greed in his heart. Terrible men on his payroll and the experience to manage them. And the way he's glaring at you right now, subtly over his glass of champagne before playing it off with a half-friendly smile and a nod of acknowlegdement... he can tell you don't belong there
