John Locke was one of the middle section survivors of Oceanic Flight 815. Before the crash his father conned him for one of his kidneys and later pushed him out of a window, breaking his back, causing him to have to be in wheelchair. After this he spent the next four years of his life paralyzed from the waist down and looking for his purpose in life. He was then told by Matthew Abaddon that he must attend an Australian Walkabout after which he found himself aboard Flight 815. His paralysis was immediately healed upon crashing on the Island, which ultimately led him to believe that he had some sort of special connection to the Island. John was very handy with tools and a good hunter of boar and other animals of the Island, which proved to be very helpful in the survival of the group. Seen as antithetical to Jack Shephard, he and Jack were philosophical opposites and used to share leadership among the survivors.
When Locke discovered a Hatch on the Island, he was determined to open it, insisting that everything happened for a reason. He opened it and took it upon himself to continue pushing the button, believing that this was his purpose. However, Locke soon lost his faith in the Island and stopped pushing the button which ultimately caused the discharge. After this, Locke looked for his purpose again and led the mission to rescue Jack from the Others. Locke eventually decided to stay with the Others and with Sawyer’s help, he passed the test of killing his father. However, his apparent ability to commune with Jacob made John a threat to Ben, who shot him and left him for dead in the DHARMA Grave.
An apparition of Walt (possibly the Man in Black or the Island itself) found Locke and told him that he still had work to do. (This phrase was previously spoken by the MiB as Christian, hinting that he was impersonating Walt.) After Jack called the freighter for rescue, John (convinced that the freighter had no intention of helping them) led a group of his supporters to the Barracks for safety, where they were attacked by mercenaries. After the Oceanic Six left and Ben moved the Island, John assumed leadership of the Others, but was immediately separated from them as a result of the Island skipping through time. Locke left the Island via the Orchid, in an attempt to stop the erratic flashes through time and bring back everyone who left. After trying and failing to reunite them, John attempted to take his own life, only to be stopped and then strangled by Ben. His death was used to convince the others to return to the Island. John’s corpse was placed upon Ajira 316 and crashed on Hydra Island along with the plane in 2007.
After the crash, Locke appeared to have been resurrected, rejoining the Others and embarking on a mission to assassinate Jacob. However, his body was discovered in the hold of Flight 316 some days later. John Locke had been dead all along and had been replaced by The Man in Black. After several days he was finally buried in the graveyard. Jack later carried on and fulfilled Locke’s goal of protecting the Island.
4×01 – The Beginning of the End
Locke found Hurley screaming for help after he discovered Jacob’s cabin. Hurley told Locke about Charlie’s death and the general situation. Locke stated that if they allowed Jack to contact the people on the boat, then Charlie would have died for nothing.
When Locke and Hurley reached the cockpit where the other survivors were meeting, Sayid argued with Locke about his true intentions, mainly about the fact he blew up the submarine. As the radio tower group arrived at the cockpit, Jack sneaked up on him, knocked him to the ground, grabbed the gun and aimed at Locke’s head. Locke assured Jack that he would not shoot him, any more than he would shoot Jack. However, Jack pulled the trigger in anger only to discover the chamber was empty. Jack began to beat Locke and was pulled off him by the rest of the survivors.
Locke informed everyone that the people coming to the Island were the bad guys, and that if they wanted to live they needed to come with him. His intentions were for them to go to the Barracks, as the Others abandoned them. Jack argued, saying that Locke was insane and only crazy people would leave with him. Though many people were loyal to Jack, some chose to leave with Locke: Hurley, Claire, Ben, Danielle, Karl, Alex, Sawyer, and a few other minor survivors. Locke and his group then left the cockpit to go to the Barracks. (“The Beginning of the End”)
4×02 – Confirmed Dead
Before going to the Barracks, Locke told his group that they had to take a “detour” to a cabin. He was surprised when Hurley made a comment suggesting that he saw the cabin (in a place it was not supposed to be). He explained to Sawyer that he was told to go to the cabin by Walt, who also told him that the people on the freighter were bad and that Naomi needed to be stopped. When pressed, Locke said that he did not question what he was told because Walt saved his life. He informed the others about being shot and left for dead by Ben. Sawyer did not believe that Locke would heal so quickly from being shot, so Locke showed him the wounds from the bullet going right through him, and said that he probably would have died if he still had a kidney in that area.
A short time later, Locke told Sawyer that they could not kill Ben because he had information about the island they needed. Sawyer was skeptical and warned Locke that Ben probably already had a plan to undermine the survivors. Locke’s group then found Charlotte in the jungle. When she revealed that she had a transponder so other members of her team could find her, Locke told her that they did not want to be found, and tied the transponder to Vincent to ensure that they would not be tracked. He took Charlotte hostage, but Ben took a gun from Karl and shot her (though she turned out to be wearing a bulletproof vest).
Locke told Sawyer that he was right about Ben, and was preparing to shoot him (despite protests from Alex and Claire), when Ben offered him information). Locke demanded to know what the monster was, to which Ben replied that he did not know, but started instead reciting information about Charlotte and the rest of her team. Ben told Locke that they were a threat, and revealed that they came to the Island looking for him, as well as the fact that he has a spy on the boat. (“Confirmed Dead”)
4×03 – The Economist
Later that day Locke and his faction found the circle of ash, but Locke was unable to locate Jacob’s cabin. When Hurley asked if they could let Charlotte go, Locke argued, threatening him and stating that he was the leader. They then journeyed to the barracks, where Locke’s faction tied up Hurley and put him in Juliet’s closet.
He then captured Sayid and put him in the gameroom with Ben. He later went into the gameroom to talk with Sayid, and traded Charlotte, whom he had been unsuccessful in questioning, for Miles. (“The Economist”)
4×04 – Eggtown
The next day he made breakfast for Ben, but Ben belittled him so badly that Locke withdrew the breakfast tray, shattering it against the wall. Kate came to Locke’s house later, asking to see Miles. Locke refused, stating that he was not running a democracy.
Later, Sawyer went to his house, and offered to play backgammon. Sawyer then revealed to Locke that Kate was planning to break Ben out. They ran to see if Ben was with Miles, but Miles was gone. They intercepted Kate and Miles down in the basement, and Locke told Kate to return to her house. He then banished her from the group, and told her to leave by morning.
Locke later questioned a strung-up Miles in the boathouse. He introduced himself by name and said that he was “responsible for the well-being of the island.” Locke then shoved a live grenade in Miles’ mouth and left him, telling him to “enjoy his breakfast”. (“Eggtown”)
4×06 – The Other Woman
Locke later revealed to Claire that he had made no progress in trying to get Miles to speak up, and Claire asked to speak to Miles herself, only to be denied by Locke. Locke then took Ben another meal only to be taunted once more. Locke kept his cool this time however, and ultimately the two made a deal for Ben to tell Locke everything he knows about the Freighter, in exchange for his freedom.
Locke agreed after Ben claimed to have visual evidence, and Ben went on to show Locke that the owner of the boat was Charles Widmore, and also revealed to Locke that his “man on the boat” was Michael. Locke held up his end of the bargain as well, as Ben was later seen walking into his own house freely. (“The Other Woman”)
4×08 – Meet Kevin Johnson
Locke held a meeting at his house to inform everyone of everything he knew about Ben and the crew of the Kahana. He made Miles confess that his team was traveling to the Island to find Ben, and Ben revealed in turn that Michael was his spy on the freighter. After the meeting, Sawyer confronted Locke and demanded to know why Miles wanted $3.2 million from Ben. Locke replied that he did not consider this to be an important issue, apparently believing that Ben did not have access to such a large amount of money. (“Meet Kevin Johnson”)
4×09 – The Shape of Things to Come
While playing a board game with Sawyer and Hurley, Locke answered a phone call. The voice on the other side repeated “code 14-J” over and over. After deliberating over what to do, Locke and Sawyer went to tell Ben what had happened, which left Ben grabbing a hidden gun and yelling “They’re here!”. Ben led Locke back to his house and told Locke if he wanted to live, Ben was his best chance, and that Ben needed Locke to survive the attack. Once inside the two began to block off the door.
When Ben brought everyone outside to see the Monster attacking the mercenaries, he told Locke he had to say goodbye to his daughter and that he would catch up with him. When Ben reunited with what remained of Locke’s group, he told them that they had to go to Jacob, at which point Sawyer decided he had had enough with the “wackos” and was going back to the beach, along with Claire and Miles.
Locke argued that they were going to keep Hurley, to which Sawyer agreed, saying if Locke got Hurley hurt Sawyer would kill him. Locke, Ben and Hurley then set off to visit Jacob. (“The Shape of Things to Come”)
4×11 – Cabin Fever
After walking the whole day, Locke decided to make camp. At night he had a strange dream, in which Horace Goodspeed asked Locke to find him, commenting that Jacob has been waiting for him for a really long time.
After that Locke made his way to the mass grave, where he found Goodspeed’s corpse. In his pocket Locke found a map to the cabin, which he immediately followed with Ben and Hurley, successfully. Both refused to enter the cabin though, and Ben told Locke that his (Ben’s) time as the leader was over and Locke’s time had begun.
Inside the cabin, Locke found Christian Shephard and, much to his surprise, Claire, who seemed to act very strange to him. Christian, speaking on the behalf of Jacob, said to Locke that all minor questions he had would very soon not matter since the freighter people were already on the way back, and convinced Locke to ask the only question that really mattered.
Locke asked “How do I save the Island?” and by the reaction of both Christian and Claire it was clear that he asked the right question, as the answer turned out to be that Jacob wanted Locke and his group to move the Island. (“Cabin Fever”)
Locke, Ben, and Hurley then moved on through the jungle to the Orchid station, the only place, according to Ben, where they could move the island. When Ben found a hidden case at a rock formation, Locke insisted that he open it himself. Locke looked through the binoculars he found inside, while Ben communicated with someone with a mirror.
Locke questioned Ben about who he was talking to. Ben refused to tell Locke, and they continued on. The three then reached the Orchid, where they found that Keamy’s team had made it there first. Ben gave Locke very specific instructions on what to do once inside the station (involving finding a secret elevator to the real station), handed him his telescopic baton, and then surrendered himself while Locke and Hurley looked on helplessly. (“There’s No Place Like Home, Part 1”)
An hour after Ben surrendered himself, Locke attempted to follow Ben’s directions, but was unable to enter the station due to his limited botanical knowledge. Jack then appeared, confronting Locke. Locke tried to talk Jack into staying on the Island, believing that Jack had brought there for a reason, but Jack was adamant about going home. As a result, Locke told Jack to lie about everything that happened since the crash to protect the Island, but Jack argued that it did not need protection. On the other hand, Locke still believed it was a place where miracles happened, despite Jack’s disbelief in such things.
Ben then appeared, and accompanied Locke into the elevator which led down into the Orchid. Upon arrival, Locke had many questions, which Ben answered by instructing Locke to watch the Orchid Orientation video. As Locke watched the video, Ben began throwing all metal objects into a “vault,” despite the fact that Edgar Halliwax instructed viewers of the tape specifically not to put any metallic objects in it. (“There’s No Place Like Home, Part 2”)
Soon after, Keamy arrived in the station, wounded but not killed from being shot by Richard. Locke confronted him, looking for a peaceful solution to the conflict. However, Keamy admitted he was never one for negotiation and earlier warned Ben that his dead man’s trigger would set off 500 pounds of C-4 on the freighter, killing a lot of innocent people.
Ben then attacked Keamy, to Locke’s protest, stabbing him in the heart repeatedly. Despite Locke’s attempts to save Keamy, (Locke cared for the people on the freighter who would die as a result of Keamy’s death, not Keamy himself) Keamy died, triggering the freighter to explode. Ben then turned on the vault, causing an explosion from within. Ben then put on a parka, instructing Locke not to follow, because whoever moved the island could never come back.
He instructed Locke to go back to The Others’ camp and take his place as their leader. Locke did so, and was welcomed by Richard. Before this, Ben apologized to Locke for making his life so miserable. (“There’s No Place Like Home, Part 3”)
