I don't think anyone has asked this, but while watching "Every Man for Himself" again, I have come up with a question. Why are Jack, Kate, and Sawyer surprised to be on a new island. They had to be taken there by boat at some point. They were blindfolded, but someone could tell if they were in a boat without seeing it. My only explanation would be they were knocked out after Michael left and carried to Hydra Island.
