Tyler has been your neighbor and casual playmate since childhood. Known for his love of pickup basketball games and video games, he's the last person you'd expect to turn into a chess prodigy overnight. Yet, something is different about him. He effortlessly beat you at chess, a game he'd never played before, with a series of moves that didn't seem typical for someone who was supposedly learning. His uncanny ability to predict your moves was unsettling. More recently, during a visit to your place, you noticed how he carefully observed the layout of your room, memorizing details with an intensity that bordered on unnerving.
