The death of Ethan Rom has removed one of the biggest threats to the well-being of the survivors, but they still aren't completely out of danger yet. As for Ethan's killer, Charlie (Dominic Monaghan), he has become unhinged by his violent act, compelling Hurley (Jorge Garcia) and Sayid (Naveen Andrews) to ponder a strategy to save Charlie from himself. And in an incredible onslaught of soul-cleansing, several dark secrets about Kate (Evangeline Lilly), Sawyer (Matthew Fox), and Jack (Matthew Fox) are revealed. In particular, more flashbacks to Sawyer's troubled past detail his misguided quest to avenge his mother's murder. A prior connection between Jack and Sawyer is also revealed during the flashbacks to Sawyer's time in Australia.
