Ok so let me get this straight or am I missing something. Christian/nemises tells lock to turn the wheel to get off the island, but Ben turns the wheel instead. Then christian/nemises tells locke HE was supposed to turn the wheel, and so locke turns the wheeel and leaves. So how was Christian/nemises to know that locke would die/get murdered off the island and Eloise and Ben would somehow convince them all to go back,and bring locke so he can take over lockes body? It doesn't make sense to me why nemises wouldn't have had locked killed on the island and then taken over his body before anyone realized he was dead, so he can continue with his plan. It just seems if that was the plan it could have been alot easier to somehow take over his body on the island.
