Chapter 11 & 12

"See? See? That's what you'll get! I meant that! There isn't a tribe for you anymore! The conch is gone" He ran forward stooping "I'm chief!"

In chapter 11 and 12 the plot is back and forth. It's suspenseful and they are full of irony. The kids are all trying to kill Ralph, he is the only kid left who hasn't joined the tribe or died. They run out onto the beach and there is a naval officer there and he asks them how a group of British boys  could have  lost all reverence for the rules of civilization in so short a time. This implies that they have all only been there for a week or maybe a month. They tried to have rules but it failed and they all but a select few turned to savagery. It is also strange that at the end the naval officer keeps saying that they were interesting to watch, and that it was a good experiment. Which almost implies that their plane crashed on purpose so that their actions could be studied.
