Lord of the Flies chapters 4&5

In chapter 4 you start to see the boys coming together as a civilization when they carry the pig down singing a song. The older boys don't like how the little ones just play around all the time, and they aren't helping. You start to see great tension between Ralph and Jack again because Ralph saw a ship on the horizon and then noticed that the signal fire was out, and that was Jack and his hunters responsibility to make sure it was still going. I wasn't very surprised that Jack hit piggy in the face resulting in lights glasses breaking because I knew that one of them was going to beat on him sooner later cause they didn't want to hear him complain. In the beginning of chapter five you see order as Ralph tries to get the boys together at a meeting to put the group back together. Once he starts explaining how no one is following rules Jack runs away and the hunters follow with him. At this part I was a little confused cause I didn't think that Jack would do that.
