The Other Woman
Named after William Shakespeare's 1610 play of the same name, the Tempest first appears in "The Other Woman" and is apparently alluded to on an unseen layer of the Dharma "Swan" station's of the second season. The writers wanted to explain some of the island's history in the fourth season and decided that "The Other Woman" would reveal where the gas that Ben used came from and that Dharma had stations set up for protection against hostile forces. They also enjoyed having Goodwin on the show and wanted to bring him back. "The Other Woman" had commenced filming by October 11, 2007 and was completed on October 30.
