Back on the island, Jin teams up with the young pregnant Danielle Rouseau and her team in 1988 where they have an encounter with the "black smoke" monster, while Locke, Charlotte, Faraday, Miles, Juliet, and Sawyer later meet up with Jin where Locke tries to lead them to the Dharma Orchid station where he hopes to turn the underground wheel to move the island in the hopes of stopping the time jumps they are going through while Charlotte's physical condition worsens with each time jump.
