So Ben and his dad were recruited to the island by the Dharma people, and then Ben decided to join the Hostiles after seeing his mom and meeting Richard, Ben is the only real Dharma person left, I wonder if the Off-island Dharma people in charge - (there must be someone who sends the food) - Do they know about the "purge" or did the hostiles just kind of move in and take the place of the Original Dharma-ists?? Did they bring Kelvin and later Desmond there too??
