Keamy's still alive, but not for long

A very much still alive Keamy takes the elevator down to the Orchid to confront Ben and tell him about the device on his arm that would kill a lot of innocent people on the freighter. Ben is hiding in the dark listening as Keamy taunts him by mentioning the gruesome execution of Alex. Locke tries to talk Keamy down, but Ben leaps out a hits him a few times with his baton before stabbing him numerous times in the neck while screaming "you killed my daughter." When Locke tells him that he's just killed all the people on the freighter, his response is a dark, cold "so." At the end of the scene, Keamy is not yet dead so the heart monitor has not trigger the C-4.
