Ralph becoming more of a leader and so he can prove to Jack that he can be as good as a leader as him. Ralph is in the woods to find the beast and the beast isn't there and then tells the boys to go back to camp before the night comes and they don't listen until he raising his voice and then they listen. That's when he becomes more of a leader.
"GO BACK TO CAMP NOW THE DARK IS COMING AND WE DON'T WANT TO STUCK OUT HERE IN THE DARK"
Ralph is becoming more of a leader telling the kids to go back to the camp in a harsh tone then a light one so he would be able to be a better leader then Jack.
Wow Ralph is trying to be a leader and take control, maybe he can be better of a leader then Jack.
