The collapsing deck accident was a fatal accident that Hurley believed he had caused some time before he won the lottery. In the episode "Dave", Dr. Brooks, Hurley's therapist, told Hurley that the deck was meant to hold 8 people, but there were 15 people too many (a total of 23) before Hurley stepped on as number 16, for a total of 24, the reverse of 42.
Dr. Brooks tried to convince him that the accident was not his fault and that the deck would have collapsed anyway because it was already overloaded.
- Damon Lindelof and Carlton Cuse joke in the 2/19/08 audio podcast that season five of the show will focus entirely on the deck collapse incident, and in fact the season would be entitled Season Five: Deck Collapse! This seemed to indicate that they did not plan on having a flashback to that event.
