Plot summary
Desmond joins a monastery to avoid marrying his fiancée and she accuses him of cowardice, prompting him to drink the wine the monastery sells and be kicked out. As he helps a monk load their wine, he meets the buyer, Penny. In the present, Desmond has visions of Charlie dying in one of Rousseau's traps while out in the jungle with him, Jin, and Hurley. Desmond gathers the three and they hike out, witnessing a helicopter crash and a parachutist landing in the jungle. They find their belongings nearby, among which is a picture of Penny and Desmond, convincing him that she has come for him. He narrowly saves Charlie when they get to the point of his death, though he fears that saving him may alter the future and prevent him from getting to Penny. They find her, only to realize she is a different woman.
