Also, how long has this island been around, and who lived there before the Dharma initiative? Sayid, Sun and Jin come across an ancient statue that has four toes, who put it there? Were they even human? I'm not sure that the show will go more in detail on that aspect of the island, but they gave us yet another confusing detail. The show writers do a great job of providing some new clue about the island, and then going back to the "normal" living of the group as if the island was just any island in the Pacific. But then they throw another detail at you that reminds you about the specific nature of the island and why nothing can be taken for granted.

The last episode of this season should end with a bang, now that Locke and Desmond have taken over the hatch from Eko and Michael's lies are exposed to the group traveling with him. One more episode which will be filled with surprises I'm sure!
