Following the implosion of the hatch and the electromagnetic anomaly the island loses its healing powers and some survivors lose their lives as a result. Kate and Sawyer escape Hydra island with the help of Alex but the Others keep Jack. Suddenly, Vincent runs into the jungle and transforms into the smoke monster. He flies for miles over open ocean until finding Michael and Walt. He explains to them that everything they have been through has been an experiment and that even the plane crash was staged. The horizon fades to black, a door appears in the distance, Michael and Walt enter, and all is revealed.
