Before the crash
Little is known about Seth's life before Flight 815. Most of the information we have comes from Frank Lapidus's accounts. Due to Frank oversleeping because of an alarm clock malfunction on September 22 2004, Seth replaced Frank as the pilot of Flight 815. ("Dr. Linus")
On the Island
Day 2 (Season 1)
Seth was unconscious when he was found in the cockpit of Flight 815, but woke up when Kate leaned over him. Jack gave him water, and Seth said he was dizzy. He was bleeding from his nose and right ear, and his right eye was bruised and swollen shut. He asked how many survivors there were, to which Jack replied there were forty-eight. He became concerned when Jack said that it had been 16 hours since the crash and nobody had come yet. He recounted the plight of Flight 815:
He then showed Jack and Kate where the transceiver was, and crawled out of the front cockpit windows to look around after the same noise from the night before occurred again. Sounds of [[|The Man in Black|the Monster]] approached, and the pilot was ripped upward from the cockpit through a windshield, kicking and screaming. The fuselage shook, then fell flat on its belly. Moments later, blood splashed across the front of the plane. Shortly thereafter Kate and Charlie found the pilot, dead, mangled in a tree. ("Pilot, Part 1")
Seth was wearing his ring at the time of the crash. ("Pilot, Part 1")
Off the Island, Frank Lapidus saw a newscast showing the supposed body of Seth in the underwater cockpit. Frank knew Seth personally and strongly believed that that was not Seth's body, since Seth always wore his wedding ring, while the corpse's hand had no rings. ("Confirmed Dead")
- In a deleted flashback scene (depicted in extras on Disc 7 of Season 1 DVD collection), Seth had a conversation with Claire at the airport restaurant before the flight. He promised her a "smooth ride." During the same extra scene, he stated that his mother's boyfriend was named Bernard. This being a deleted scene, it may not necessarily be canon. However, a woman in "The Oceanic Six: A Conspiracy of Lies" mentioned witnessing this scene. If the mockumentary is considered canon, then this scene actually did take place, at least in part. Part of this scene was shown in another Bad Robots Production show - Fringe.
- In the making of the pilot episode, it is revealed that the pilot character was added late in production, as Jack had originally been planned to be killed off in "Pilot." The pilot's body that was found hanging in the tree was also originally intended to be Jack's.
- Seth was the first crash survivor to be killed by the Monster. The Monster did not claim a second victim until Day 72.
- Seth was the first speaking character to be killed and the second overall after Gary Troup.
- Although the pilot was featured in "Pilot, Part 1", his name was first revealed in the fourth season episode "Confirmed Dead".
- Out of the main characters, he has met Jack, Kate, Frank, and possibly Claire (if the deleted scene is considered canon).
