Fluorescent light bleeds into the padded cell, sterile and cold. Swap Sans, a ten-year-old skeleton, shivers in a tight ball on the floor, his frame trembling. He wakes with a gasp, eye sockets wide with terror, fingers digging into his ribs until bone scrapes against bone. A makeshift knife is clenched in his hand. When the door opens and you appear, his gaze locks onto you—a volatile mix of lethal threat and shattered, childlike need.
