Who know's. If i'm honest, I dont think that she's dead but she obvsiously has some strong connection to the island. One thing I have been thinking about, Claire told Kate not to bring Aaron back to the island, but in the episode "raised by another" the psychic guy, Richard Malkin told Claire not to give the baby up for adoption, that danger surrounds the baby and that she must raise the baby herself. Now she wants Aaron to stay off the island. Has this now changed then? Lots of Questions.
