What about you?: How Ben knows more than you think by Dio

I won't bother with formalities

The most pivotal scene in The Incident was Ben killing Jacob. My theory is that Jacob wanted Ben to kill him. Not only did he want him to kill him, but he instructed him to kill him. That's right, contrary to what Ben may have said while in the presence of MIB, Ben has met Jacob. He may have only met him once. But despite Ben questioning Jacob about where he has been for the past 30 years, Ben and Jacob are on the same side. Jacob's murder was part of a plan to deceive MIB into thinking he was in a position of power, when in fact, he is not. Ben's line from This Place is Death rings especially true here "If you knew what I've done to keep you safe, to keep your friends safe, you wouldn't stop thanking me". Ben and Jacob may have orchestrated more events in order to complete some greater task. Ben does seem to have a considerable amount of knowledge of events yet to unfold, and he seems to act with a great sense of purpose. He knows that all he does is for Jacob, but he canno! t reveal it to anyone, otherwise it might be possible that MIB could catch on. Jacob is not going to stay dead, or at least he will still have an ability to effect events (through Hurley?). Jacob would not have just let himself die. He is planning something big.
Go crazy.
