Having been kidnapped several episodes back, Claire (Emilie de Raven) suddenly re-emerges. The other survivors pump her for information, but she can remember nothing of her ordeal -- nor of anything that occurred since even before the plane crash. Meanwhile, Claire's self-proclaimed abductor, Ethan (William Mapother), threatens to methodically kill the others unless the girl is returned to him, forcing Charlie (Dominic Monaghan) into violent retribution. And more flashbacks reveal just how low Charlie had sunk in his heroin addiction prior to the plane crash. ~ Rovi
