The latest episode of Lost had the Smoke Monster, in the guise of John Locke, bemoaning to Kate about how tough it was to have a crazy mother.
The primary plot driver in Lost seems to be the SM's conflict with "Jacob", who's keeping SM bottled up on the island. And it's a conflict that's been going on for (at least) centuries.
So a light bulb went off. Bad feelings for mom. An ongoing hatred for Jacob. All those years of Sunday School weren't a total waste. Could the SM really be… this guy?
But then I Googled it, and guess what? There's probably no semi-plausible Lost theory that other people haven't already put forth and discussed to death.
