I know that Sean must be here, somewhere. It takes me a moment to spot him, but by now I know how: look for the place with no movement, for the person who’s just a little part away from the rest. Sure enough, there he is, standing with his back to the cliff, an arm across his stomach, his other elbow resting on it. His knuckles push tightly against his lips, but his face is expressionless. There’s something terrible about the way he stands there, watching. He’s not so much still as frozen.
