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. Two people died, and Hurley developed severe depressive symptoms of stress and psychosis as a result, and was admitted to the Santa Rosa Mental Health Institute by his mother, Carmen.
