Uncharted Island

Juliet sure knew a lot about Jack when she opened up that gigantic file and began telling him about his college days, his career, and his marriage.

It’s been postulated that she could’ve gotten this information from Ethan, who lived among the survivors for a while, or from Ben when he was imprisoned in the Swan hatch. Or from Jack himself as a side effect of whatever drug he was given when he was first captured. Or maybe, just maybe, the Others have contact with the outside world via the internet or satellite or something.

I think it was the smoke monster. You know, we haven’t seen Smokey since he faced off with Mr. Eko in the jungle in “The 23rd Psalm.” When Mr. Eko faced off with Smokey, there were little electrical flashes of his memories in the smoke. What if the Others control Smokey, or can at least communicate with it? I also think that Smokey changes form and appearance, so just because Jack didn’t come face to face with a big black smoke monster doesn’t mean he hasn’t encountered Smokey. Smokey could’ve grabbed some of his memories to be “read” by the Others.

Perhaps it’s a little more “out there” than the other suggestions, but it does help tie things together a little better from earlier episodes.
