In an attempt to avoid a massive wall of text that scares the shit out of people and makes them not read it, I shall continue what I previously began.
I didn't know exactly where they'd take the show, and in what ways they'd describe the Island. And I couldn't predict the exact qualities they'd give their fictional world, if any.
But I expected it.
From the first moment, in the series Pilot, that they gave a glimpse of what would end up being ol' Smokie, I knew this series would treat us with some wild and fanciful shit.
When they first hinted that all the characters were kind of linked together in some way, I expected the writers were up to something.
When they first brought in the Hatch and the first descriptions, I expected it to be a ruse, truthfully. But when it blew up, so did the ruse. Something was definitely crazy about the island, though truthfully I did expect it could go either way.
To keep this brief, I'll skip many. I'll enjoy watching the entire series again on Blu-ray (currently somewhere in Season 2, kind of put it on pause when Season 6 started), because I can definitely remember quite a few scenes where some things were rather blatantly connected, but they hadn't been spelled out, nor were they touched upon much further. Many scenes from the first half of the season, were given new meaning with scenes in the later half.
The writers knew the general direction of the series the whole time. That's my big point here: most of these big twists and revelations, they weren't concocted just to keep things fresh, they've had the paths of the characters charted for the whole series, especially since midway into Season 3. For the whole series they had it all planned out, but what they left open was some of the more minor events that were in-between the big points. What the characters would say, what would happen to some characters for 10 minutes as they walked after getting water... no, that wasn't planned. However, they let the story write itself, so to speak, as the plot drove on. They had the plot written, and the characters written, the smaller interactions weren't charted specifically until closer to those moments.
But anyhow... when time travel was brought into the picture, I REALLY knew something was going on.
And recently, when Jacob described the island as a cell of sorts for Smokie, I expected that could go either way. And it still might, that much remains to be seen.
When it was described that Smokie leaving the island would mean destruction of everything... I expected that could end up meaning anything. It could be a metaphor, it could be a ruse for more power play, or it could be straight fact - smokie leaving the island = humanity's end game.
And now, that last line, is looking quite true.
What I got out of this episode?
MiB (seriously, I am upset they didn't reveal a name. That's just ridiculous.) fell into the light.
"Mother" described to Jacob that contact with the light would not mean death, but worse than death.
MiB made contact with the light, and died. But he didn't die, he became immortalized in a cloud of smoke. His physical body is gone, but touching the light caused him to turn into something else.
What I gather is, Smokie IS MiB. MiB figured out tricks he could pull off as time went on, that includes taking the form of dead people.
It seems people are up in arms about the whole "Light" concept.
I'm not. In fact, I just don't care. The show is a big ride for me, the plot devices are simply there to help drive the characters. The characters provide the entertainment.
Seeing the back story between the two brothers, imho, was especially pleasing.
As for the Light, right now I am equating it something along the lines of The Flame of Olympus. And the Island is Mt. Olympus.
The Light is the source of all order in our world, and as "Mother" described it, it literally is the life-force in all life (or at least in humans).
Something tells me a human making contact with the Light, and turning into a powerful force, means a lot of the power contained within the Light is held within Smokie. Which would also explain why Smokie can see into the lives of those it examined (think back to Mr. Eko and the flashes in the smoke), and might also explain the whole concept of seeing dead people on the island... when people die, their life-force, or soul if you will, returns to the magic vessel of life called the island, and returns to the pool of Light. ... maybe, who knows where they will go with that one.
But since Smokie is "part-Light", and the Light is supposedly something desperately in need of protection from outside interference... it could be gleamed from this that Smokie, leaving the island, would mean a breach of the Light into the rest of the world. The Island is supposed to be basically a big secret from the world, so that people cannot just search for this light and make such a breach a possibility.
I'm sticking to this Mt. Olympus analogy, with the Light being extremely important, because it seems exactly where the show is going.
And personally, I think that does the show justice.
The show has always been about psychology, philosophy, sociology, and a little religion. And ancient mythology has been brought into play quite a few times, either in passing comment or in larger themes. Wrapping up the show with very strong ties to ancient Mythos would be fitting, as the ancient Greeks involved a lot of those similar, very human themes in their stories.
The entire series, the writers always hinted at the concept of the island being, well, different. And the characters constantly debated whether the island was special, or if it was just a bunch of crazy shit on an otherwise ordinary island.
Turns out, it's a little of both.
