I have a question which I am not sure has been answered yet, or if it is not very. What is the purpose of the Dharma Initiative on the island. The original DI seemed a research based corporation. If that was the case, why would they continue to fund the island after the purge and Ben's coup? How is DI related in anyway to Jacob and the mythological aspects of the island? It seems the numbers Desmond pushed in the computer were the numbers relating to the corresponding numbers to potential replacement caretakers. How did DI get those numbers if Ben had never spoken to Jacob. What was Richard's role as intermediary between DI and Jacob?
