If the Abrams and Lindaloff (sp?) are able to end the show after four or five seasons, I think we will start getting answers of some kind soon, either directly or indirectly. In this episode, A Tale of Two Cities, we got a number of answers, but they were all indirect ones;
• The Others are not hillbillies, but live in a well maintained community with contemporary technology.
• The Others are also in contact with the outside world – they are getting clothing, books and information about the Lostaways.
• Benry (Who I now think may be an incarnation of Randal Flagg) is the leader of the community. No one questions him. It seems he leads the group like Jim Jones led his own cult.
• They are setting the Lostaways they are holding up for some brainwashing where they will (try) to make them think the Others and Benry are cooler than sliced bread.
No one “told” the Lostaways this information, we (the viewers) just had to pay attention.
So I expect we will learn more about the jabberwocky (i.e. the guardian smoke monster), the Dharma Initiative, the Others and so forth and so on. We will just have to pay attention.
