So what’s the deal, the hydrogen bomb worked, as Juliet said from beyond the grave? Does that explain the dual narratives, one with the cast still on the island, the other at LAX? Are they not present and past, or present and future, but present and present? That is, have we moved on from time travel to the multiverse theory, in which different universes can coexist? To me, that’s the only explanation that makes sense. Curious as to what anyone else thinks.
