I agree. I think the Others' "neighborhood" is on the same island as where Jack, Kate and Sawyer are being kept. They also have a camp and that's on the island the Losties are on.

Still not quite sure why none of the Losties have noticed the 2nd island. The island they are on is so small, you'd think they would have explored it thoroughly by now.

Although, the Others and the smoke monster (where is that thing by the way?) may be preventing the Losties from going to the other side.
