MAJOR SPOILER
A brief preview of a supposedly "non-spoiler" scene from the finale was shown (I CONSIDER IT MAJOR SPOILAGE, NO MATTER WHAT TPTB SAID - read at your own risk). FLocke coils a rope around his arm as he and Ben are looking down into Des's well. From nearby bushes, Sawyer watches them.
Sawyer is noticed and comes out of the bushes. He calls FLocke, "Smokey", and says that FLocke doesn't have to have him or the remaining survivors killed anymore as there is no longer any further need. He also states that someone else other than the Losties rescued Des. Sawyer also reveals that the Losties know FLocke wants the island destroyed. Ben states that he thought FLocke was speaking metaphorically about destroying the island and FLocke reveals he is going to sale off the island on a boat. FLocke studies the area around the well again and notices a canine pawprint.
