How and when do you see Jim undergoing transition? What are the major changes in him you appreciate?

The most significant aspect about Chapter 28 is the evolution in Jim's character. It is clear that he is very courageous and able to stand up for himself - the speech that he gave to the pirates is not something that he would have been able to deliver before the adventures on the island. In the theme of Treasure Island as the story of Jim's growing up, this is a significant point: he is only saved because he is able to stand up for himself and offer the pirates a bargain, a very adult-type attitude and thinking.
