When a reigning martial arts champion drags a quiet stranger onto the mat for a cheap laugh, he doesn't expect the stranger to smile. He definitely doesn't expect to beg.The air inside the Chicago Metro Sports Arena was thick with the scent of floor wax, stale popcorn, and overheated bodies. It was the annual Midwest Combat and Fitness Expo, a sprawling carnival of protein powder vendors, flashy heavy bags, and localized testosterone.At the center of it all, bathed in the harsh glare of overhead halogen lights, was the main exhibition mat. And holding court on that mat was Derek Lawson.Derek was 24, carved out of granite, and possessed an ego that took up more square footage than the arena itself. He was a third-degree black belt, a regional kickboxing champion, and currently holding an undefeated amateur MMA record that he made sure everyone knew about. With a microphone taped to his cheek and a pair of customized red sparring gloves strapped to his hands, he was running his favorite segment of the day: Survive the Champ.The premise was simple and entirely self-serving: any amateur from the crowd could step onto the mat and try to last two minutes with Derek. If they did, they won a hundred bucks and a T-shirt. If they didn't, they became a highlight reel for Derek's rapidly growing social media presence."Come on, people! I barely broke a sweat on that last guy!" Derek's voice boomed over the PA system, echoing off the high tin ceiling.He bounced on the balls of his feet, executing a lightning-fast spinning hook kick that stopped inches from the referee's nose. The crowd of roughly 300 onlookers gasped and then cheered.Derek smirked, eating up the adoration. "Who's next? Don't tell me Chicago is out of tough guys! I got a crisp $100 bill right here. Who wants it?"The crowd murmured. The last tough guy was a local college wrestler who had been clinically dismantled in 45 seconds, currently sitting by the ice coolers, holding a cold pack to his bruised ribs. Nobody was eager to volunteer for public humiliation.Derek paced the edge of the mat, his eyes scanning the perimeter like a hawk looking for a slow field mouse. He didn't want another athlete. Athletes knew how to cover up; they made things boring. Derek wanted a spectacle. He wanted a stark contrast. He needed someone who looked like they had never thrown a punch in their life—someone whose sheer awkwardness would make Derek's fluid athleticism look even more godlike.That was when his eyes landed on Thomas Weaver.Thomas was standing near the back of the crowd, leaning against a concrete pillar near a vendor selling overpriced foam rollers. He looked to be in his late 40s, maybe early 50s. He wore a pair of worn corduroy pants, a sensible gray zip-up sweater over a faded button-down, and wire-rimmed glasses that kept sliding down the bridge of his nose. He had the kind of unremarkable, slightly weary face that you instantly forgot after seeing it in a grocery store aisle. In his right hand, he casually held a paper cup of black coffee.
