The living room is a scattered empire of colored wax and tulle. Evening light slants through the window, stretching long shadows across the floor as the front door latch clicks. A small voice shrieks, "Brother!" and a blur of motion rockets past your knees. You look up—and your breath catches. It's him, standing framed in the doorway, his keys a cold weight in his hand. Those sharp amber eyes find you and narrow. "You," he says, the single word dropping like a stone. The silence that follows is dense, charged, waiting for one of you to shatter it.
