What’s Juliette’s “mission”? Before The Other took off, Ben told Juliette that he’d see her in a week.
I (and a lot of other people) have been assuming that Juliette is up to something that isn’t very good, because of everything else that’s happened.
I got to thinking about this some more, and realized that while Juliette is probably trying to get to Sun, it might just be to warn her about what might be happening to her. (Women that conceive on the island end up dying).
We know that the father is either Jin or Jae Lee. If it were Jae Lee, chances are the Sun will be OK. Why? Because Claire was pregnant before getting to the island, and she’s OK. If Jae Lee was the father, Sun wouldn’t be in any danger, but Juliette might try and get to her to see what they can find out about her pregnancy.
If the father is Jin, then it’s BIG trouble for Sun, and Juliette could be there to try and talk Sun into getting some therapy or SOMETHING to help her, because she’s going to die otherwise.
Either way, whatever is happening, it doesn’t look good for Sun. She’s either going to have to admit that she’s the mother of Jae Lee’s baby (which has pretty dramatic implications for the Jin/Sun relationship), or she’s going to die unless Juliette helps her.
Either way, I think Juliette is there to help Sun. I think it’s probably that The Others know about Jae Lee, and when Juliette tells Sun she knows about that, it’ll be what convinces Sun that Juliette is actually trying to help.
….Of course, as usual, this is all theory, so we’ll see how it plays out when “D.O.C” (Date of Conception) airs in a couple of days.
