So they live on one island and work on a different island? Hmmm. It is true at the end of season two Ben had Jack, Kate, and James all on the dock. Maybe they took them to this other island, all we know is season three started out with them already in their cages/aquariums. But wouldn't it be safer to live on the other island, too? Danielle has been wandering around crash site island for 16 years. I don't know - invisible island vs. crash site island threw me for a loop.
