Jack, Hurley, Sun, and Lapidus then run off to join Sawyer and Kate at the docks, hoping to abandon the Man in Black and seek refuge at Hydra Island with Charles Widmore's people. Claire later joins them, but Jack leaves because he wants to stay on the Island, per Jacob's request. Upon arriving there, Sun sees Jin and finally reunites, breaking her aphasia. However, Widmore's people throw them into cages, Widmore claiming this is for their own good. That night, the Man in Black, as the Smoke Monster, attack the base, and Jack frees them. Meeting with Sayid, they make their way to the Ajira flight, but the Man in Black claims that if they are to escape the Island, they should take Widmore's submarine. At the dock, however, Widmore's men engage in a gunfight with them, forcing the submarine to leave Claire and the Man in Black behind. Inside the sub, Jack discovers C-4 in his pack, realizing the Man in Black set them up. While Sawyer wants to disable it, Jack assures that it will be alright, since the Man in Black cannot kill them unless they tamper with the bomb themselves. Sawyer does so, not trusting Jack, but increases the timer. Sayid runs off with the bomb in a suicidal move, trying to save some of the others; it detonates, flooding the sub. Sun is pinned to the wall by fragments, and Jin desperately tries to free her. As the submarine slowly floods, Sun begs Jin to leave her, but he insists on staying, telling her in Korean that they will never be apart again. They share one final passionate kiss and embrace before they drown, holding hands. Shortly after she died, Jack, Kate and Hurley all cried over her and Jin's deaths.
