The episode is centered on Hugo "Hurley" Reyes, while Desmond Hume and John Locke also received points of view in the flash-sideways universe.

In 2007, Hugo "Hurley" Reyes (Jorge Garcia) starts to think destroying Ajira Airways Flight 316 is a bad idea.

Hurley then visits the Santa Rosa Mental Health Institute, where Libby tells him that she remembers them meeting following a plane crash on an island.

Desmond observes their date from a distance, before driving off and visiting the school at which Ben Linus (Michael Emerson) and John Locke (Terry O'Quinn) teach.

As Hurley voices his concern, Ilana puts down her bag containing the unstable dynamite too hard, causing it to explode, killing her.

He takes Ben and Miles (Ken Leung) with him to the Barracks to collect explosives, while Jack (Matthew Fox), Frank (Jeff Fahey) and Sun (Yunjin Kim) remain with Hurley.

The Man in Black explains to Desmond that people built wells looking for the source that made compass needles spin at points like this location.
