I don't think you missed anything important. Probably just the part where they decide they need to kill Ben, but Ben tells them they can't kill him because they need him for answers, then he tells them the full names of the four new comers to the island. Ben says that the reason why he knows these things is because he has a spy on the freighter. Meanwhile Kate, Jack, Syid, and Juliet are with the new comers and they discover that Juliet was not on flight 815 and Miles pulls a picture of Ben out of his pocket and asks where he is, and that the real reason they have come to the island was to collect Benjamin Linus. Interesting thing about the picture is that in it he looks like he is in an off island office dressed in clothes I would estimate to be from the 70s or 80s. The little pop up text box at the bottom of the screen admits that this photo seems to indicate that Ben has been lying about never having left the island during his adult life.
