Seamus stood up. He just stood straight up and gazed directly up the slope for perhaps two seconds and got an excellent view of the sniper, who was ensconced on a rock in the seated position, rifle at the ready, but gazing over the top of his scope, taking in a general view of the scene. The sniper reacted quickly, raising the weapon and getting his eye socketed into the scope, trying to find Seamus with it. But as Seamus knew perfectly well, these things took time. Seamus had a pretty good idea of how long they took. The transition from normal vision to the world as seen through the scope was jarring and confusing to the visual system no matter how many times you practiced it; the scope was never aimed in exactly the right direction, you had to swing the barrel around to bring the target into view, and there was a tendency to overmove it when you were hurrying to catch up with something that was moving rapidly.
