Firstly, LOVED Ab Aeterno! When MIB spoke to Richard, he said something on the lines of 'the devil betrayed me, he took my body, my humanity...'. Jacob "took" his body? For what? So basically the MIB we've seen is just another vessel for MIB like Locke's? Or could it be that Jacob did something to MIB that turned him into Smokey and now he can't maintain corporeal form all the time (?) Or was he just lying to Richard (although why it would make a difference to Richard is beyond me) Thoughts?
