I'm guessing that the guys in the fishing boat are the infamous
"Others," who seem to have a thing for children. Actually, the
whole situation with the way they snatched Walt, coupled with the
previous abductions/attempts, puts me in mind of faerie
mythology. Where the fae would snatch healthy children and leave
changelings in their place, because they were unable to have their own
children. Obviously there aren't any changelings here, lol, but I
wonder if the child-snatching has a deeper purpose. (I guess they
could be really fussy cannibals! o_O )The flashbacks at the end were
extremely poignant. Everyone busting their asses to get on this
doomed plane, and throughout it all, just going about their own
business like the complete strangers that they are. The contrast
between that and the current situation where they depend on each other
to survive is staggeringly huge. I suspect that it was designed
to show exactly that, and to also give us the feeling that maybe,
despite everything, the latter option is the truer, better one. :-)And
aside from everything, I really, REALLY want to hit Charlie. *furious*
