Do we think that Juliet's prime target now is Sun? Even after she begged Ben to bring her home, he said no. His reasoning was because her work was not doen yet. Do you think that she is infiltrating the Losties to get to Sun so that she may continue her work so that Ben will allow her to leave?

What I don't get is why don't the others themselves go and kidnap Sun or Aaron. They surely have the man power to do that. Other thing: if the whole Claire's abduction was to put an implant in her to make her sick whenever the right moment arrives, it means that Ben had the whole Juliet's mission plan from the beginning. So what's with her and Jack leaving in the submarine? Who was gonna carry out the mission if Juliet wasn't gonna be on the island anymore? What would have happen to Jack and Juliet if Locke hadn't blown up the sub? Just like Ben said, Locke's plan was a dream come true for Ben. Maybe this is why he believes on the island (magic box) so much.
One of the best episodes so far.

I think Juliet is after Aaron.... Ethan tried to get him already but failed. Now Juliet is making a second attempt.

I don't think Juliet knows Sun is pregnant yet. If she finds out, there will definitely be consequences.
