After watching it again, I didn't see any children in their island village, just adults. Maybe that's why they are so interested in the kids from the tail section and with Walt, and Claire's baby. Maybe there is some reason why they can't have children of their own????? And they were all very clean-cut and kind of nerdy looking -like a cult type thing. But not neccesarily religious because the one guy at the book club meeting objected to the book "Carrie" as being full of religious themes and science fiction. Their lives looked pretty boring, and Juliet's mood at the beginning seemed kind of upset, like she was trying to calm herself with some light-hearted music, and face another day there. She didn't seem very happy..... anyone else see that???? she obviously doesn't like Ben very much. he's not invited to her book club!!
