Well, I have been re-watching Season 2 before going to bed (I've got the episodes on my iPod, so I tend to watch a couple before passing out)...
I think a major factor in the survival and lives of the Lost crew and the Others, plays majorly into "the incident" that is about to take place in the next couple weeks...
(The next Lost episode is entitled, "Follow the Leader", then followed by the season finale, "The Incident Pt. 1" and "The Incident Pt. 2"...
The Swan is a major factor, that is for sure... but what about Desmond? He is obviously alive, and the Island obviously needed him to push that button -- then Dan Faraday's mother comes along and says that Desmond must return.
And what is up with her, by the way?! She goes and shoots her own son?! And how did she come to be on the island, and how did she get off the island?
And from what I understand... Faraday and Penny are half brother/sister, or full brother/sister? Charles and Ms. Hawkings seem to have some sort of connection that we don't really know about just yet. Could this be the reason that they were sent away from the island?
It's very confusing!
Love to hear what others have to say.
