I have a theory about the island. Here it is: A potato skin is bland, but good for you. Many vitamins and nutrients can be found in potato skins. However, people do not like to eat them. They are bland, and most people just like to eat the inside of the potato. This is bad, because then those people are not as healthy. The potato skins represent being the protector of the island. They are not what everyone wants, but better for you. No one (except Jack) wanted to be the protector of the island, but it is good for his soul. Thoughts?
