Great theories by EW’s Jeff Jensen
Jeff from the EW site posted great theories. Although it does not count all of the island elements (symbols, whispers, etc.), he had an idea of it by looking at the island in a larger picture.
Also, these are theories that does not talk about alternate timelines, so it’s a refreshing read!
I suggest to skip to the second page (there are six read-worthy pages).
I don’t want to talk about his ideas, so just read it for yourself, if you want to:
PS. In his article, I like the underlying theme of “rescuing the children” throughout each season. Would Season 6 do the same?
