Keamy kills Dr. Ray and Captain Gault

When Frank says he's not going to fly Keamy and his team back to the island, Keamy, in another act of brutal violence, slits Dr. Ray's neck and throws him overboard. Captain Gault shows up firing a gun in the air and tells Keamy to stand down. Keamy points out the device on his arm, Gault turns to ask "What's that on his arm?." Keamy then shoots Captain Gault. Frank then agrees to fly the helicopter back to the island.

In the end, Captain Gault died a hero. He didn't seem to accomplish much, but he did help Sayid leave the freighter.
