When considering what you will write, be sure to maintain verisimilitude. That is, keep Ralph in character. To do so, perhaps, you want to reexamine the second to last paragraph of the novel:
For a moment he [Ralph]had a fleeting picture of the strange glamour that had once invested the beaches. But the island was scorched....Simon was dead--and Jack had...The tears began to flow and sobs shook him. He gave himself up to them now for the first time on the island; great, shuddering spasms of grief that seemed to wrench his whole body....Ralph wept for the end of innocence, the darkness of man's heart, and the fall through the air of the true, wise friend called Piggy.
Judging from this paragraph, it seems in character for Ralph to be very truthful. (Do not forget that his is the British society of Australia that does have great respect for honor.) In addition, his love for Piggy, especially, should provide the impetus for him to be very candid. And, it seems that after Jack and Roger have burned the island and attempted to slaughter him, Ralph will have no problem in implicating them in their attempts at murder. Probably, Ralph will mention the lack of adults and the fears of the small boys, their imagining of a beastie, etc. These extenuating conditions may help to mitigate the descent into savagery by Jack and others. However, in the British society of the 1940s, there would not be too much leniency.
So, with these ideas in mind, you can devise your interview as we editors do not write for you. But, here is an example that may get you started:
Q: All right, Ralph, we understand that you and the boys were stranded for ___months after the plane crash. Tell us, now, what happened after all of you were there on your own. Were there tensions among you? You have said that you were the leader, but was there some rivalry with another boy or boys? What happened?
A: Jack Merridew was the leader of the choir. From the first, he wanted to be in charge of his boys. Later, he said he would be the hunter and kill the pigs that were on the island. Well, there was another mean boy--Roger--who liked being a hunter. I mean, he liked to hit and hurt. Uh,....
(There should be some hesitancy on Ralph's part, so have the interviewer, who is an adult, draw the truth from him as Ralph tries to circumvent the brutal truths.)
I would think that in interviewing Jack one would get a very nervous and condensed version of what had happened to Piggy. Jack has a lot to try and cover up but it is doubtful that he will want any blame laid on himself.
I believe that Jack would try and tell the interviewer that he was the one to make sure that everyone had survived by having enough food to eat. However, there were some situations that had been awful. One of the boys had charged out of the jungle and they thought he was the beast attacking them and he fell to his death. As far as Piggy is concerned he would either lay the blame on Roger or say that a boulder fell and knocked him down.
Ralph will probably be more honest and tell exactly what had happened from his perspective. He has nothing to lose by telling the truth. He had not been involved in murder or become the savage that the other boys had become.
Interview (Explaining the death of Piggy and Simon to their Parents.)
In an interview format, what reasons did Jack or Ralph give to either Piggy or Simon's parents on their death. Did they tell the truth? Exaggerate? or Lie completely?
Please explain more and put the answer in interview format. Thanks!
