Hurley has flashbacks of when he was in the mental hospital. His friend, Dave, didn't want him to get thinner. It turns out that he made Dave up. Libby is also there.
Libby helps Hurley try to solve his problem with weight. More food arrives from the sky. Hurley sees Dave on the island and freaks out. Dave tries to convince him that the island is all fake and just a dream. Libby shows up just in time to save Hurley, who is about to jump off a cliff. They kiss. Locke goes on crutches. He and Sayid talk to "Gale." It is confirmed that he is an "Other."
This episode was great! I want to know more about "Gale." Also, the ending with Libby was great! This episode gets a 9.5 out of 10!
