Cabin Fever
Ben tells Locke that the true leader of the Others is someone named Jacob. Locke wants to meet him. Apparently, Jacob lives in a not-so-lovely cabin in the woods. When the two men go inside, Ben introduces Locke to Jacob. But all John sees is an empty chair. Then he hears a voice say, "Help me." There's a flash of light. The cabin shakes with frenzy. Ben and Locke scramble out of the cabin. Locke asks what happened and Ben replies, "That was Jacob."
