1. They decide that their only choice is to travel to the Castle Rock to make Jack understand the importance of the signal fire to any hope the boys might have of ever being rescued.
2. Ralph blows the conch shell, but the guards tell them to leave and throw stones at them, aiming to miss. Jack orders his hunters to capture Sam and Eric and tie them up. Roger kills Piggy when he rolls a boulder down the slope towards the camp. Roger and Jack torture Sam and Eric, forcing them to submit to Jack's authority and join his tribe.
3. Roger pushes a boulder off a cliff and it starts heading towards Ralph and Piggy. Ralph dodges the bolder, but it hits Piggy which shatters the conch and sends him to his death.
4. Roger, always eager for violence, edges past Jack in order to "show him" how to attack Sam and Eric. Roger shoves Jack, almost but not quite pushing him aside, in a symbolic action to discard human morals and turn fully to animal desire.
1. Ralph learns of Jack's specific plans for him from Sam and Eric. In chapter 12, when Ralph is on the run after Piggy was killed, he encounters the twins. They are terrified and they are in Jack's tribe now, but not by choice. They have been tortured and forced to be part of Jack's tribe. ...
2. First, he feels frustration and anger, but quickly realizes that will do no good. Then he tells the twins where he is going to hide with the implication that they will lead the hunters in a different direction. Then, finally, he asks them what will happen to him once he's found. He goes from trying to talk them into helping him to acceptance of his fate.
3. Early in the final chapter, Ralph, in hiding, watches the boys as they feast. He notes that their savagery has increased tremendously. There is no mistaking their similarity to uncivilized savages. As he thinks about all that has happened, he refuses, at first, to believe that the boys could have purposely become killers. Then he encounters the skull of the sow that Jack killed and impaled on the stick. It appears to be grinning at him regards Ralph, "...like one who knows all the answers and won't tell." Ralph realizes, then, what Simon and Piggy knew - that the real beast, the real source of evil, was inside of each one of them. He also slowly comes to realize that just as Simon and Piggy died for gaining this insight, he, too, is likely to die. When he encounters Sam and Eric and they tell him that Jack and the tribe plan to hunt him like a pig and that Roger has sharpened a stick at both ends, Ralph feels even more certain that his fate is to follow Simon and Piggy. Even though he never articulates the idea as much as Simon or Piggy, Ralph has come to realize that understanding the source of evilness comes with a price and that price is death. At the end, when he is rescued instead of killed, he weeps for, among other reasons, the loss of innocense. His realization of the source of evil robs him of ever being innocent again.
4. The contrast in the behavior of Samneric in Chapter 12 of "Lord of the Flies" is unexpected:
The twins were examining Ralph curiously, as though they were seeing him for the first time.
At the end of Chapter 11, Roger approaches the twins who lie in terror after being told by Jack that they must "join the tribe." Later, when Roger "advanced upon them as one wielding a nameless authority," the twins become savages. For this reason they examine Ralph in Chapter 12 as though they have not seen him before. Just as the twins have felt terror, so, too, does Ralph feel "a spasm of terror" that sends him shaking. For, he senses the evil inherent in the remaining boys as do Samneric when they are advanced upon by the sinister Roger.
That Samneric are now hunting him disturbs Ralph greatly as this behavior of the twins is not what has been typical of them. When Ralph finds them painted, they are ashamed that they have yielded to the "nameless authority" of evil.
