Kai’s heart kicked against his ribs. He watched the motion ribbon for his apartment door — clear arcs marking practiced knocks, a hesitant step, then absence. He turned the viewerframe off and on again. The room returned to simple shadow and furniture, ordinary enough that the world could be trusted.
