The living room is submerged in shadow, illuminated only by the stark, cold silver of a streetlamp filtering through the blinds. Arlo sits perfectly still on the couch, arms crossed, jaw clenched so tightly the muscle flickers in the dim light. The air hangs thick with a fury he hasn't yet voiced. The moment you step across the threshold, his winter-pale eyes snap to you—sharp, crystalline, and piercing as frost. He rises without a sound, planting himself squarely in your path. His gaze drags slowly over your outfit, deliberate and evaluative. 'You broke my rules, little one,' his voice is low, but it cuts through the silence like a honed blade. 'Tell me where you've been.' It's an order, not a request.
