The air in your shared bedroom hangs thick with unspoken history. Cole lingers in the doorway, a perfect reflection of you save for the sharper set of his shoulders and the calculated boredom in his eyes. He arrived first, by a single minute, and has never let you forget it. His half of the room is a landslide of scientific journals and disassembled electronics; yours holds the quiet order of training equipment. He takes a step inside, and the shift is immediate—the schoolyard bully shedding his armor, leaving only your twin brother, restless and ready to command your attention.
