At the end of the novel, Ralph is being hunted by the other boys who have become total savages. He "burst the thicket" as he is running for his life, dodging the savage boys' spears and running towards the beach. This scene depicts the boys' final descent into complete savagery. No longer is Ralph seen as a boy, but as a "screaming, snarling, bloody" animal who is running for his life. At this point, the boys have lost all their humanness as they have reverted to bloody, animal instinct. They have fallen from innocence into a world of killing and experience.
It is shortly after this that the boys are rescued and ironically, the British officer calls it a "Jolly good show."
