Discuss Simon the "queer" one. Where does he go at the end and what does he do?

In Chapter Three, Simon is wandering alone in the forest. He followed Jack and Ralph halfway up the beach toward the mountain, then turned into the forest with a sense of purpose. He is a tall, skinny boy with a coarse mop of black hair, brilliant eyes, and bare feet. He walks through the acres of fruit trees and finds fruit that the smallest boys cannot reach. He gives the boys fruit, then proceeds along the path into the jungle. He finds an open space and looks to see whether he is alone. This open space contains great aromatic bushes, a bowl of heat and light. Simon eagerly takes in the complex sensations of the forest, and he stays peacefully enclosed in a "cabin" of leaves until long after day has faded into night.
