Jacob sits outside a building sitting on a bench reading Flannery O'Connor's Everything That Rises Must Converge. Seconds later John Locke falls onto the ground after having been pushed out the 8th story window by Anthony Cooper. He appears to have died on impact, until Jacob approached him, and after touching his shoulder, Locke gasped and opened his eyes. Jacob told him everything would be fine, and was sorry this had happened to him. Locke was unaware that this was Jacob.
After he left the Island, Sayid is with Nadia, celebrating their one-year anniversary. Nadia insists they go somewhere nice to celebrate, though Sayid is reluctant. Jacob asks them for directions, distracting Sayid while Nadia is hit by a car. Jacob touches Sayid's shoulder before he runs to her side.
Ilana is in a hospital, heavily bandaged. A nurse tells her that despite the nature of her injuries, she has a visitor. Jacob comes to her and asks her for help.
In 2007, Hurley is being released from prison. He tries to convince the guard that he shouldn't be released because he is a murderer. The guard says he's been discharged and should go to the cab stand in front of the building. He gets in a cab with Jacob already sitting as a passenger offering to share the cab. Jacob has the guitar Hurley will bring onto the island beside him. Jacob asks Hurley why he won't go back to the island. Hurley replies confessing he believes himself to be cursed, being the cause of all the death and tragedy that has surrounded him. Jacob tells him he is blessed in his abilities to speak with the dead and that he is not crazy. He tells Hurley about Ajira 316 and tells him all he has to do is be on that plane. He tells Hurley that it's his choice and that he doesn't have to do anything he doesn't want to. As he leaves the cab Hurley tells him he left his guitar to which Jacob replies, "It's not my guitar."
On the Island
Jack and Sayid dismantle the hydrogen bomb in the tunnels under the DHARMA Initiative's barracks, in order to remove its core. Richard Alpert and Eloise Hawking assist Jack and Sayid in entering the barracks via the basement of one of the houses. Richard knocks out Eloise to prevent her traveling with them to detonate the bomb because she is pregnant. Sayid dons a DHARMA jumpsuit in order to fit in at the barracks; they almost escape when Roger Linus recognizes him and shoots him. Jack and Sayid escape in a van driven by Hurley, along with Jin and Miles. Hurley drives to the construction site of the Swan station, while Jack treats Sayid's wounds, however they are stopped by Juliet, Sawyer and Kate.
Jack and Sawyer discuss the situation away from the other survivors, with Sawyer expressing his opinion that "what's done is done" and that they shouldn't try to change the past. Jack claims that it his destiny to change the past and that John Locke has always been right about the island. Jack and Sawyer get into a fist fight, which is broken up by Juliet, who now agrees with Jack that they must detonate the bomb. Juliet then breaks up with Sawyer, claiming that although they love each other, they are not meant to be together, and that if they never meet then she will never have to lose him. With everyone now on the same page, Jack enters the construction site of the Swan station at the same time that security officer Phil arrives with a team of armed men. On the orders of Radzinsky, Dr. Pierre Chang continues drilling into the energy source beneath the construction site. A massive gunfight ensues, wherein the survivors gain the upper hand, allowing Jack to drop the bomb into the pit at the same time that the drill hits the energy source. All metal items are suddenly pulled into the pit, causing Phil to be stabbed by a steel bar, Dr. Chang's arm to be severed and Juliet to be dragged into the chasm by a metal chain. Sawyer grabs her hand, but is unable to save her; she falls to the bottom of the pit, and Sawyer cries. Severely injured, Juliet hits the hydrogen bomb with a rock 8 times until it detonates.
Their group arrives shortly after Ben and Locke enter a chamber in the base of statue. Ilana asks for "Ricardus" and Richard identifies himself. Ilana asks Richard "What lies in the shadow of the statue?", and Richard replies in Latin, "He who will protect/save us all." Ilana reveals the contents of the crate: John Locke's dead body.
Inside the chamber, Jacob correctly deduces that Locke is really his rival and that he has tricked Ben into coming there. Jacob tells Ben that whatever he has been told, he still has a choice in what he will do. When Ben asks Jacob about all the times he has been neglected, putting to him the question, "What about me?", his only reply is, "What about you?" Upon hearing this, Ben stabs Jacob repeatedly. Jacob whispers to the man wearing Locke's form, "They're coming," and the impostor pushes Jacob into a fire.
