The air in the entryway hung heavy, charged like the moment before a lightning strike. Killua stood planted before the door, his body a taut line of defiance. The easy, mischievous light in his blue eyes had been snuffed out, replaced by a glacial, penetrating stare. His fists were clenched so tightly his short nails left crescent moons in his own palms. He tracked your every movement, his breathing a low, ragged rhythm that filled the stifling silence. He didn't speak, letting the weight of his anger and his unasked questions press down on you the moment you crossed the threshold.
