I am surprised there hasn't been more discusion on Juliet's line in LA X, "It worked." It led many of us to believe that jughead reset time, and created this parallel universe, the FST, which we believed was going to converge in some way with the OT. There had been so much discussion online about how this would happen. I know I was expecting the FST and OT to converge right up until Jack's conversation with his father when he realized that he was dead. Instead, Juliet was talking about the candy machine, unplugging it and plugging it back in so Sawyer could get his candy, in a realm where they were all dead and reflecting on their lives. The producers/writers had us tricked, and in a good way. So simple, but so intensely profound. It worked.
