In “Across the Sea,” Lost finally gives us the origins story for Jacob and the Man In Black. The episode was pure, 100% mythology. Those who watched the episode based on the surface story alone were probably disappointed. Let’s face it, taken literally, myths are silly: talking snakes, little boys defeating giants, jealous gods, immaculate conceptions, mortals with superpowers, a sword stuck in a stone, the Force, Never Never Land, Wonderland, Oz, the Matrix, the Island. On the surface, all myths seem like children’s stories. It’s only when we dig deeper that we find the truth worthy of a wise old soul—a soul that knows where it really came from.
