Well, i didn't expect that to happen. At first i thought y would they make another season after that. Then some Jeremy guy is telling them they Have to go back. It really doesn't make any sense.
And i believe Claire is still alive. They nvr showed her dying or said anything about it. So i think she is still on the island just like Sawyer and them. I'm kinda disappointed on how it ended but im looking 4ward to seeing how the next season goes.
