Everyone seems to either be at the beach or in the hatch these days. Jin and Sun are on the beach now, although they had been living in the caves. (Ditto, Claire, Hurley and Charlie, right?) And we've seen Jack sleeping in the hatch (does he have permanent dibs on the lower bunk now that Sawyer's well?) So has everyone vacated the caves?
Seriously - did they lose that set? We never see anyone there anymore -- not going for water, nothin'! The last time I can recall is when Jack comes back to tell everyone they've opened the hatch.
