"Yes and no... she is playing them"
Is she really? Was the attempt to have Jack kill Ben during his operation real or another manipulation by Ben and Juilette - does it go back that far? How does she even trust/work with Ben anymore? It seems awfully strange (unless Ben has promised to send her home - even after the sub was destroyed) that she can go from contempt for him to helping him so faithful in his ploys
Yes, I agree that she could very much be working it to try to get off the island too; but my point was more that everything she did in this week's episode was scripted by Ben beforehand. And I do think she definitely has the possibility of coming over from the Dark Side; she definitely is infatuated with Jack.
And while the past weeks have shed a LOT of information, there still is a LOT about the island that remains a mystery; like how the plane broke up; how they all survived the crash; the numbers thing - 42 23 16 15 8 4 (come on, its one thing to dig up info about Sawyer's background; another thing for all the stuff that happened to Hurley); Locke's health; all the connections with the passengers before the flight; the black creature; the whole DHARMA thing; the fact that the big black guy's brother died in a plane crash on the same island; Hurley's girlfriend and the asylum; etc...
lets see... what else did I miss?
