[Ghoulish Delight]

They "answered" those questions in only the absolute most superficial way possible. Instead of "Jacob's protecting the island and the mysterious magnetic energy it emanates," it's now, "Jacob's protecting the island and the mysterious light energy it emanates." Instead of "Jacob somehow became the protector of the island and will do anything to protect it," it's "Jacob's 'mom' somehow became the protector of the island and will do anything to protect it." The episode did nothing to either answer the underlying questions behind any of it, nor even ask any new interesting questions. It just slightly altered the nitpicky details of the questions, leaving the same overall view of what's going on.

I didn't say I'm giving up on the show or that this episode makes me any more or less worried about the ending. But this episode did nothing to move the story in anything more than trivial ways.
