Lost: Man of Science, Man of Faith

"Man of Science, Man of Faith" is the first episode of the second season of Lost and the 26th episode overall. The episode was directed by Jack Bender and written by Damon Lindelof. It first aired on September 21, 2005, on ABC. The flashbacks focus on Jack Shephard's struggle to heal Sarah, who would later become his wife. In real time, John Locke and Kate Austen decide to enter the now-open hatch shaft. While writing the season premiere, the producers decided to pick up the hatch storyline which was left hanging after season one's finale "Exodus", leaving the raft events to be explained in the following episode, "Adrift". "Man of Science, Man of Faith" received positive reviews, and stands as the most-watched episode of the series in North America, with 23.47 million viewers.
