In April 2007, I wrote a theory about LOST: Why The Others Are Desperate To Get Women Pregnant.
Here’s a revised version of the theory. (This might be a repost, but I can’t find the original, so I’m posting this anyway).
The island has powers that The Others don’t want the outside world to exploit. The problem they have is that they can’t get pregnant, and therefore have to go “off island” and recruit people to the island to replenish their numbers. The big problem with this is that every time the recruit, they risk exposing the island to the outside world. The Dharma Initiative, whatever their original intentions, did expose the island to the outside world. Ben helped The Other purge the island of The Dharma Initiative.
Since then he’s been on two missions. One, get rid of anyone in the “real world” who knows anything about the island. Two, figure out a way to get women on the island pregnant so that no one every has to leave the island.
As for what Ben and The Others are protecting…. No idea. But it’s something they don’t want people like Widmore exploiting, so it must be pretty important.
Unlikely as it might seem, Ben might actually be one of the good guys.
Update – What are they protecting? Duh! I should remember my own theories – They’re protecting their knowledge of time travel. I should know better than post when I’m not feeling well…
