What I'm wondering about is the bizarre season ending. How did Katya know that Vaughn was torturing Lauren? Sark had no access to her. The only person I can think of is Jack, as he was so adament about Syd not finding out what Lauren knew and making sure that Vaughn killed Lauren. So maybe he suspected that Syd would get to Vaughn and convince him not to kill her, but torture her, and he was afraid Lauren would tell Vaughn. Did Jack send Katya after Vaughn? I mean, how did they find Vaughn so quickly then and rushed him to the hospital? Jack showed up pretty soon after. This is unusual for Jack, though he did sit around w/ Vaughn, waiting for him to wake up when he got sick from the red ball disease. And why was he just injured and not killed? This would mean that Jack put trying to keep Syd from finding out his secret ahead of catching key players in the Covenant (i.e. Lauren) Now, at first I was thinking that this couldn't make sense, bc Katya tried to kill Sydney too, and that would mean she's not on Jack's side (I hope!) But then again, maybe he sent her after Syd too and she wasn't really going to hurt Syd, just take her away @ gunpoint so that she wouldn't confront Lauren. I don't know. I actually hope this isn't true, but it's suspicious.
