In the sixth season, the story always unfolds with two narrative clues. In one, they are on the island. In the other, they also took that flight, but the plane did not crash, so everyone lives a completely different life outside the island. Desmond discovered the connection between the two worlds, so he went to find those who had been on the same plane one by one, and used various extreme methods to make them "remember" the days on the island that they had not actually experienced. Many people who had never met came together, fell in love, and lived happily together. On the island, they had already lost each other for various reasons. In the end, Jack saw the happy smiles of these companions at his father's funeral, and he smiled too. Jack, who had been struggling with fate and responsibility, was truly liberated the moment he "woke up".
