So, now we know… lots of stuff. Whether anyone likes what we now know is an entirely separate matter, but this was an episode that gave fans what we have been clamoring for: tons of answers. Maybe not the answers many of us were hoping for, but answers, nonetheless.
In one sense, it’s hard to criticize the episode that finally revealed: the origin of Jacob; the origin of the Smoke Monster; why Jacob and the Man in Black hate each other; who set up the “rules” for their conflict; the origin/significance of the white and black stones; why MiB wants off the Island so bad; where the donkey wheel came from and what it’s for; what Jacob is guarding on the Island; what job the “candidates” are being culled for; the identities of “Adam and Eve”; and the source of the Island’s strange powers.
Turns out, it’s a kind of magic.
