Explain Richard? How about explaining Claire and Sawyer?
Yes, Richard had an off-island identity at Mitelos, he could blend right in. But I'd love to be at the press conference with the rest of them! Frank, who was supposed to be the pilot of the original 815 crash, ends up going missing with another plane that happened to be carrying five of the Oceanic Six to Guam of all places! And then he mysteriously returns with just one of the Six and two more of the original 815 passengers!
My random thought was, "Will Kate get another big payday from Ajira this time?" and "Will somebody finally put all of these people on a no-fly list?"
