Neville was working on clearing a line of sand, and as he glanced at Olivia, he stopped what he was doing to watch her carefully filling up part of the hole. Shrugging, he looked over at Hannah, who had gone to fetch her camera, and he turned back to the sand.
Moving around, kneeling and crawling, Neville extended his line to become a trough, piling the extra sand on top of the center. When he got enough, he started pushing and pulling bits, to shape it into more of an organized blob. Olivia was still concentrating on the trough, moving to fill parts up, seemingly content and focused.
