He fights for his life with israel hands on the hispaniola, and kills hands by accident (but he was ready to kill him on purpose). he bursts into tears, and began, witnessing silver's murder of the crewman tom, almost faints. throughout, he reports every incident faithfully, revealing very little about his own feelings. at the end, he says he wants no more of treasure island, but he does not explain why. about all you can glean from all this is that jim is a smart, good hearted, and relatively courageous adolescent boy, one who is writing a report and not baring his soul. thus jim is entirely believable as a character — the world is full of people about whom you know no more than you do about jim — but he is almost entirely closed.
