How has Jack changed?

Jack has changed a little in Chapter 6 because he use to be just all about hunting and always going against Ralph. He still is about his hunting but he shows a little change in attitude with Ralph. When Ralph was climbing the cliff by himself Jack appeared right behind him and said "Couldn't let you do it on your own". That shows that Jack was willing to go with Ralph and had his back with finding this "beast". Also when Ralph made a demand for all of them to go back to the mountain to light the fire Jack didn't argue with Ralph he simply went along with him. Jack is showing that he is actually on the same "team" with Ralph right now but you can see that the old Jack is somewhat in him still.
