The Devil betrayed me and stole my body, my humanity… explained MIB to a bewildered Richard Alpert about “the Devil” (that we know as Jacob).
We know that MIB is now appearing/using the identity and bodily form of John Locke, even though there is a dead body of John Locke buried on the island.
We know that MIB also takes the form of Smokey. We have seen Smokey make appearances as other people such as Alex and Yemi.
We know that the reason Ilana dragged around the coffin containing Locke’s dead body at first was because she wanted people to see who they were up against given that FLocke/MIB can no longer take on any other appearance. (It seems like we should get back to the meaning(s) of this statement before the show’s end. It feels kind of like a “rule” of sorts.)
I just can’t shake the idea that MIB was something like the first candidate, and he made some sort of deal with Jacob (maybe not necessarily the Jacob that we know) similar to the deal between Jacob and Richard. If that is the case, it would seem possible that somewhere along the line Jacob has done to MIB what MIB has done to John Locke.
If this was easy to figure out or explain, I don’t think I would bring it up, as usually only the writers can make anything make sense…usually. Since I can’t understand it and readily acknowledge that there are a couple of significant pieces missing (how/why/then what is Jacob?), it makes it that much more intriguing as an actual theory.
I’m sure we could look past this line as another manipulation, given that MIB’s instruction to Richard on how to kill the Devil were exactly the same as Dogen’s instructions to Sayid. Yet I think the writers added this line about how there is a “stolen body and humanity” situation in the middle of these other familiar statements (to us viewers) to be purposeful.
Ultimately we know that MIB has been the one using different forms and appearing as various people, but the fact that MIB revealed that his body was stolen and points it back to Jacob seems pretty important.
(Wish I could have posted this sooner after Ab Aeterno…oh well. It still seems relevant in the long run somehow.)
