It looks like we're back to the time-travel-mystery-ship storyline again, because Desmond and Sayid return in tonight's episode. Oh, but wait- was that a note that just got slipped under the door of the room they're locked up in? Could it really be that Ben was telling the truth when he said he had a spy on the boat?
