Answer:
piggy
Step-by-step explanation:
In "Lord of the Flies," it is Piggy who stays behind with the littluns when the older boys go off to investigate the beast. The following quote from Chapter 6, "Beast from Air," describes the situation:"Piggy remained outside, a reluctant guardian. The littluns were around him, keeping as close as possible, peering at the risen sun through the trees. Piggy moved among them, a massive figure of authority and defeat, sat on the earth, his left side toward the sun."
