Anyone else get the feeling from some of the scenes, Juliet and Jack, Sun looking at the boat door, Charlotte and Daniel on the beach that this will be the last time some of these people will see each other for a long time, at least until the Oceanic 6 get back to the island?

Charlotte's look said, "don't leave me behind damnit," to me :)

To me it showed a genuine concern and a human side of Charlotte we haven't seen from her, she really cares for him, I think she may become a sympathetic character yet. (Assuming she isn't gunned down or ripped apart by the smoke monster?

Yes, I definitely got that feeling. But I think (hope?) Daniel makes it back. He's got work to do. He's probably the only one who will know how to "move the island" back so it can be found by Jack and friends.

Or, on the flipside of that, he is one of the few who could find it if he is left out in the world, although I would like to see him on the island. Although a feeling of impending doom hung over this episode even though we know the Oceanic 6, no matter what they've been through will be safe.

Oh I definitely felt some of those ominous goodbye looks... it was very well done, from the acting, framing and scoring.
