 While Sun, Jin and Sayid head off to the Others-camp, we follow Locke and Desmond who locked themselves up in the Hatch. Ecko and Charlie are trying to free them because Ecko thinks it s not smart what Locke and Desmond are doing. Desmond s background story is revealed showing his time in a military prison in his native Scotland, his later run-in with Jack, his decision to sail around the world, and how he came in the hatch and the history of the hatch. Meanwhile, Kate, Sawyer, Jack, Michael and Hurley are heading of to the Others but the Others capture them thanks to Michael s betrayal of them in exchange to be reunited with his son. In the hatch, Locke and Desmond find out why and how the plane is crashed. Michael and Walt meet again and the Other s leaders, Mr. Friendly, Henry Gale and other foot soldiers permit them to return to the real world. The Others release Hurley who has to go back to the camp with a message while Kate, Sawyer and Jack remain. The final shots tell us that Desmonds wife is still looking for him and some researchers are too.
