ne brat spoiler ?
"You think the Losties were always dead ? Wrong.
Everyone that lived on the Island, cept for those which were actually the black smoke monster in disguise ( as in Jack's father in the first season ), were alive, those that died, obviously died.
You can see Hurley and Ben in front of the Church, how they congratulate each other for doing a good job on the Island, right ?
That is because they probably lived another hundred years or whatever on that island, long after jack died, and they did that Jacob thing.
The alternative World, in which they are all happy jolly golly is timeless, because its the afterlife, it's as simple as that.
In that world they were all dead, but that doesn't mean they all died in the "real world" at the same time.
They lived their lives and eventually died, and ended up in that "alternate world" in which they meet in the church, regardless of when they actually died.
Its simply the place they gather after dying to "move on" ( probably going to heaven or something, or who knows, maybe reincarnation, think for yourselves )
So yeah, Kate and everyone on that Plane, they went back home and lived their lives. Until eventually they died and ended up in that other world.
Do i repeat myself ? Yes, just to make it clear.
So anything else ? Uhm.. well yeah, obviously they were brought to the island to replace Jacob and prevent Flocke from escaping, they were not meant to die, and some did not die , like those on the plane and everyone left on the island, bernard and rose and hurley and ben and desmond.
So what can i say ? Yeah many questions are unanswered, like where does the source come from and the like. But everyone that is explained makes sense and i loved it, simply loved it."
