Plot summary
Juliet has an affair with Goodwin Stanhope, and when he dies, Ben takes her to see his body. She accuses him of setting Goodwin up to die, and Ben affirms that she belongs to him. In the present, Daniel and Charlotte sneak off and Goodwin's widow warns Juliet that they are going to the "Tempest" station, which the Others used in the purge to gas DHARMA. She finds them at the Tempest just as Daniel is using its computer, but they convince her that they are neutralizing the gas to prevent Ben from using it. Juliet admits to Jack her fear that Ben will kill him because of her, and they kiss. Ben informs Locke that the Kahana belongs to Charles Widmore, and when he reveals who his man on the boat is, he is allowed to live comfortably with the survivors.
