I think that the people on the Rescue Boat want to blow up the Island,and they are part of a cult. Also the Island is like the Earth's Core. and if they destroy the Island the World gets blown up now I think that the Survivors are gonna want the Others back. I know what your gonna say it sounds like I have been playing too much Halo. But it just hit me and it sounded like a good theory. What Do you think? Tell me what you think. you can add others iff you may like.
