I haven't seen any posts on this question, so if it's been done to death, please excuse me.
At various times, key characters have referred to the Island as if it were a self-aware entity with plans of its own: Ben, I think, more than once when talking with Locke; Mr. Friendly telling Michael that the Island was not going to let him off himself; and Eloise telling Desmond that the Island was not done with him. There may be others, but those are the ones I recall.
Unlike Locke, who may be conflating "the Island" with Jacob or MIB, these three characters know about Jacob, but they do not say Jacob.
Is it possible that the Island is more than a mere setting for the Jacob v. MIB throw-down? Will the Island intervene to influence the outcome of that conflict, or end it?
