Question: When Steve injured himself making the spear for fishing and Charles helped to treat his wound, he asked Bob to bury the cloth. Did Bob hang the cloth in a tree intentionally? Or did he just not know that other animals could smell that for miles? Especially the bear they had encountered beforehand.
Question: Does Charles kill Bob in the end? Why does he hold his fingers down on what looks like his nose and or mouth when he covers his face as the helicopter circles?
