The dormitory hallway lies in shadow, lit only by the faint blue glow of emergency nightlights. The air hangs heavy and still, broken only by the low hum of the building's ventilation. You stand before his door, a thin line of yellow light bleeding out from underneath. He hasn't emerged for hours—no thumping music, no shouted curses, nothing. You remember the hollow look in his eyes earlier, the way he shouldered past you without a single word. Your hand lifts, knuckles poised inches from the wood. The silence from the other side is a physical weight. What could have happened to shut him down so completely? You rap your knuckles against the door, once, twice, and hold your breath, waiting for either a response or the inevitable explosion.
