What a great episode!!First -- I think the future was a dream. I don't think the Losties will get off the island -- at least not yet.
Did anyone else consider this? What if Ben is right? What if Naomi is/was working for a whole new set of "bad guys." What if the Losties and the Others must join together now to fight the new "bad guys?" It is interesting to me to think about how they will keep this show alive for however many seasons are ahead. After all -- how many Others are still around?
That was really strange to see Walt back on the island helping Locke. We always knew that kid had special powers. Do you think it was Jacob appearing as Walt to Locke?
We also saw Patch/Cyclops use up another of his nine lives. He has seven left. What a creepy guy. Wouldn't that grenade have killed him as well? Somehow, I don't think so.
Sawyer -- you can tell he is screwed up after being forced to kill Locke's dad. I don't blame him for shooting the last Other standing on the beach. You cannot and should not trust them. We've seen that too many times before.
Lastly, there is hope! Charlie spoke to Penelope and confirmed that Desmond is alive. She will not give up looking for him and we are left to believe that one day, they will be reunited.
