 In this episode Hurley is the main focus of the flashbacks. We find out that he is very insecure of his weight because years earlier he stepped on to a deck that collapsed with 23 people on it, killing two... one of them being his father. After this incident he suffered a mental breakdown and becomes catatonic and his mother checked him into a psyche ward. On the island, Hurley is suffering for his "sickness" which is his over indulgence in food. He has set up a stash of food in a hidden location. With the help of Libby he destroys the stash, only to be deterred by the new supplies that have landed on the beach from a transport plane. He then begins to start seeing this man that is in a bath robe that Hurley recognizes. In the flashbacks to the psyche ward, we find out that Hurley had this friend Dave that was incarcerated with him. This turns out to be the same guy that Hurley is seeing on the island. Through a doctor patient conversation Hurley is told that he is imagining his friend Dave, and that Dave is the self-destructive part of his mind, always telling him to eat and never lose weight. On the island, Hurley asks Sawyer for some medicine that will help him control his hallucinations. But naturally, the mean-spirited Sawyer refuses and makes fun of him prompting Hurley to beat Sawyer up. Hurley packs camp up and moves to the caves. On his way out he meets Dave again and Dave tells him that everything he is seeing is in his head. He tells Hurley that he is in a self induced coma still in the psyche ward. Dave then says that he has to jump off a cliff to wake up. Hurley stands on the cliff contemplating suicide so that he can wake up, when Libby comes out and tells him that he is sane and that everything has happened. This leads to Libby and Hurley kissing and everything is fine. Then in a flashback we see Hurley acting all happy in the psyche ward, while Libby is across the room a mental patient herself mumbling words to herself. This is where Hurley has seen her before.
