Veronica Hamel of Hill Street Blues fame makes a guest appearance as the mother of plane-crash survivor Jack (Matthew Fox) as he experiences another of his character-revealing flashbacks during a period of delirium. Elsewhere on the island, the pregnant Claire (Emilie de Raven) suffers from unforeseen complications, and Boone (Ian Somerhalder) gallantly attempts to rescue a drowning woman, only to be nearly drowned himself. It seems that there may be a thief on the island, as the last of the water bottles mysteriously disappear just when Claire desperately needs them. And Jack continues to "see" a mysterious man in a suit at a distance; when he goes to investigate, he finds that the stranger may be, impossibly, someone very close to him. ~ Rovi
