Lost: Season Four Finale

S04E13 and S02E14: 'There's No Place Like Home: Parts Two and Three'

Keamy and his men are ambushed and defeated by The Others in the forest after Kate distracts them. Keamy is savagely attacked by Sayid. Linus, now free, thanks everyone and tells Kate and Sayid that they are welcome to leave the island.

At the Orchid station, Locke urges Jack to lie about everything if he does ever leave the island. Linus and Locke head underground and the latter watches a Dharma Initiative video involving time travelling rabbits. A wounded Keamy turns up in search of Linus, warning that he is wired up to a heart rate monitor that will trigger the explosives on the Freighter if he is killed. Nonetheless, Linus attacks and kills him as revenge for the death of his daughter.

Linus tells Locke that he will be the new leader of the Others as he cannot return to the island after moving it. Linus then goes through a hole, wearing a Parka jacket, and climbs through an icy passage to reach a large metal wheel.

Frank, freed from his handcuffs by Sawyer, leaves the island on the helicopter with Hurley, Jack, Kate, Sawyer and Sayid. However, there's a fuel leak and Frank fears they won't reach the Freighter unless they lose weight. Sawyer whispers something to Kate, snogs her, and jumps into the sea. He swims ashore and is greeted by Juliet.

On board the Freighter, Michael seeks to prevent any explosion by freezing the detonation battery with liquid nitrogen. When Keamy dies, the explosion is delayed but the nitrogen is running low. The helicopter turns up, refuels and takes off again with Desmond added to the passengers. Jin doesn't make it on board though and Christian Shephard appears in front of Michael just before the massive explosion.

The helicopter passengers see the island vanish in front of their eyes, with Jack disputing Hurley's explanation that Locke succeeded in moving it. With nowhere to land, the helicopter crashes into the ocean but everyone makes it on board a liferaft, where Desmond is given mouth-to-mouth by Jack.

At night, Penny Widmore's boat arrives and finds them. Jack convinces everyone to adopt a cover story to save those who remain on the island. One week later the future 'Oceanic Six' sail on a dinghy to a small Indonesian island after saying their goodbyes to Frank and Desmond.

In the future, Sun finds Charles Widmore in London and suggests they talk. Kate has a nightmarish vision of Claire cradling Aaron before urging them not to go back to the island. Sayid shoots a man who has been monitoring Hurley in his hospital and then urges him to leave his chess match with Mr Eko to head for safety.

A man called Jeremy Bentham has been approaching survivors from the island, including Walt. Jack breaks into a funeral parlour to see Bentham in his coffin. He encounters Linus in there, who says that all the Oceanic Six must return to the island together as bad things have taken place since they left. Linus says that Locke must return too, for his dead body is in the coffin under the alias of Bentham.
