S2E18 · Dave

Complete story — includes the ending

At Santa Rosa, Hurley's friend Dave convinces him to eat as much as he can. His doctor gets him to discuss the incident that put him in the facility, in which a deck collapsed and killed two people while he was on it, explaining that Hurley is using Dave to punish himself. He proves this by showing Hurley a picture of the two where only Hurley is visible, leading Hurley to reject Dave's offer to escape. In the present, Hurley confesses his eating disorder to Libby and destroys his food stash at her encouragement, only to panic when he sees the new pallet of food. He starts seeing Dave, who tells him that he lapsed into catatonia and hallucinated the island, and that he needs to jump off a cliff to wake up. Libby finds Hurley and kisses him to convince him he is in reality. Henry admits he is an Other and tells Locke that he never entered the code, and that the timer reset on its own. Another flashback reveals that Libby was also a patient at Santa Rosa.
