For an island in the South Pacific there sure seem to be a lot of white people on it.
But yeah, this episode answered questions that I'd forgotten about (Adam and Eve) and did not deal with questions I'm highly concerned with (Why is MiB leaving so bad, why does Jacob have a magical lighthouse, who built the statue).
With Jacob and MiB's origin, there's now the bigger question of how Jacob can manipulate destiny if he's just some normal dude.
