I thought it was interesting how Flocke recruited Sawyer. He said Jacob came to him in a point in his life when he was vulnerable and lead him down his path to get to the island and it was not his choice at all. Now we have Sawyer again vulnerable because he just lost Juliet. This is when Flocke recruits him and takes advantage of his current state. So basically Flocke did the same thing as Jacob and apparently Sawyer had no choice.
One last note. How is Sawyer going to get out of that cave???
