I dont know if any of you already talked about this, I haven't been on here in like months. But this came to me randomly. I still like to think that its not the monster that takes forms of dead people, but for the sake of arguement I'll go with that for now. What if the monster can take form of people who died on the island (Alex, Yemi, etc.) and Nemesis can take form of people who died off the island (Christian, Locke, etc.).
