What did Jim see in the ship?

While he is waiting, Jim listens to the voices coming from the ship's cabin. Immediately, he recognizes one as Israel Hand, the other he only identifies as wearing a red nightcap. Clearly, from the sounds of their angry voices, the men sound tipsy. Once again, a breeze comes up and puts the rope in a perfect position and Jim cuts through the rest of the rope. Upon this action, the Hispaniola begins to slowly spin and sway with the current. As he is shoving away from the bigger boat in the smaller oracle, Jim catches a rope and hoists himself into a position where he observes the two sailors in a physical struggle, a struggle that to Jim appears deadly.
