After Ralph wounds the pig with the spear, the boys begin to re-enact the scene, with Robert as the "pig". When the "game" loses its "playfulness", what might Golding be foreshadowing?

Robert begins to cry in pain and panic from the boys' "game". Robert is very close to being seriously hurt before the reenactment finally stops. I think this foreshadows the jump from killing pigs to killing other boys on the island.
