Plot summary
The body of the Kahana doctor, Ray, washes up on the beach. Daniel calls the boat and tells the survivors that rescue is on the way, but Bernard Nadler translates the message's morse code and reveals he is lying. Jack presses him into admitting that the survivors's rescue was never a part of their mission. Keamy's men kill most of Locke's group and he kills Alex when Ben refuses to surrender, so Ben summons the smoke monster in a tunnel under his house to fend off Keamy's men. He and Locke force Hurley to search for the cabin.
In the future, Ben awakens in a Tunisian desert and travels to Iraq, where Nadia Jaseem has been killed by one of Widmore's agents after marrying Sayid. He sets up the killer to be killed by Sayid and recruits him as his assassin, then goes to meet Widmore and promises to kill Penny. Widmore resolves to regain control of the island.
