On the Island
Ben walks into the foot of the statue where Ilana is crying, staring at her fallen teammates. She asks Ben what happened to them and Ben says that John Locke killed them after turning into a pillar of black smoke, also (falsely) indicating that the Man in Black killed Jacob as well. Ilana then asks where Jacob's body is, and Ben tells her that the Man in Black kicked Jacob into the fire and he burned away. ♪
A crab is seen resting behind Locke's corpse's ear. It scurries off when Frank covers the corpse with a tarp, noting that Locke is "getting ripe." When Sun tells Ilana that the other people have gone to the Temple, Ilana urges the rest (Sun, Frank, and Ben) that they should also go there, as it is the safest place on the Island. Sun is sceptical until Ilana suggests that if Jin is alive and on the island, he is also at the Temple. ♪ Before they leave, Sun says they need to bury John.
While Ben, Ilana, Frank, and Sun bring Locke's body to be buried at the survivors' gravesite, Ben asks Ilana why she brought Locke's body to the statue. Ilana responds that she needed to show the others what they were up against.
Ben then asks why the Man in Black wouldn't just change forms again, and Ilana replies that the Man in Black is now stuck in Locke's body.
At the survivors' burial ground overlooking the sea, the group digs a grave and puts Locke's body in it. ♪ Ilana asks if anyone wants to say anything, and Ben, with some reluctance, says that he knew Locke, that Locke was a "believer, a man of faith," and that he was "a much better man than I will ever be." He adds that he is "very sorry [he] murdered him," which appears to take Sun and Ilana by surprise. As he and Ben begin to fill in the grave, Frank comments to himself on the oddity of the situation, musing that it's the "Weirdest damn funeral [he's] ever been to." ♪
The Man in Black
The Smoke Monster makes its way across the Island. From its perspective we see it pause at the Barracks outside of Sawyer's former house, inside of which loud rock music and the sounds of things breaking can be heard. ♪ It returns to the jungle where eventually the Monster comes across a machete lying on the ground. The Monster then transforms back into the form of Locke and cuts a battered Richard Alpert down from a tarp hanging from a tree, telling him it's "time to talk." ♪
The Man in Black gives Richard a drink of water and tells him that he wants what he has always wanted: for Richard to come with him. Richard asks why the Man in Black looks like Locke, and the Man in Black informs him that he knew that John Locke could get him close to Jacob because he was a "candidate." Richard appears baffled by this response, and when he prods further, the Man in Black responds with restrained sarcasm, incredulous that Richard would follow Jacob without knowing what he was following him for. The Man in Black then claims that he, himself, would never have kept Richard in the dark. Again the Man in Black asks Richard to come with him and promises to tell Richard everything, but Richard firmly declines his offer. At that moment, the Man in Black sees a mysterious blonde boy, whose arms are covered in blood, appear behind Richard in the jungle. Richard doesn't appear to see the boy. The Man in Black asks Richard to come with him one final time, insisting that people "seldom get a second chance". When Richard declines again, the Man in Black, slightly shaken after seeing the boy, walks away saying he will see Richard sooner than he thinks. ♪
The Man in Black walks to Sawyer's house, from which he hears music playing loudly. ♪ Upon seeing the Man in Black in Locke's form, the drunken Sawyer says "I thought you were dead." The Man in Black replies, "I am."
Sawyer pours a glass of whiskey for the Man in Black and himself. The Man in Black tastes but does not drink his. Sawyer says he "doesn't give a damn" if the man before him is dead and tells him to "get the hell out of [his] house." The Man in Black tells Sawyer that this was never his house, that he just lived there for a short time. Sawyer says that he doesn't believe that the person in front of him is Locke because Locke "was always scared" while this version of Locke is not. The Man in Black says that, if Sawyer comes with him, he can provide the answer to the most important question there is: "Why are you on this Island?". Sawyer replies that it's because his plane crashed here, his raft blew up, and the helicopter taking him to the freighter was too heavy. The Man in Black says that's not the reason, and that he can prove it if Sawyer comes with him. Sawyer agrees to go along. ♪
As the Man in Black and Sawyer walk through the jungle, the Man in Black asks why Sawyer is not at the Temple with his friends. The mysterious boy appears in the jungle again, but this time his arms are not bloody. When Sawyer takes note of the boy, the Man in Black seems shocked that Sawyer can also see him. The Man in Black chases the boy into the jungle, eventually falling and looking up to see the boy standing above him. The boy tells the Man in Black, "you know the rules, you can't kill him." At this, the Man in Black becomes furious and exclaims "don't tell me what I can't do" much as John Locke once did, in a mixture of fear and anger. As the boy walks into the jungle shaking his head the Man in Black, now yelling, repeats his statement to the boy.
Meanwhile, a frantic Richard approaches Sawyer and urges him to go to the Temple, telling Sawyer that the Man in Black "wants everyone dead." Sawyer refuses, insisting the Man in Black promised him answers. Richard's attempts to convince Sawyer are cut short as he hears the Man in Black approaching and flees back into the jungle. The Man in Black asks Sawyer who he was talking to and Sawyer says "nobody". Sawyer then asks the Man in Black if he ever caught up to the "kid" to which the Man in Black wryly replies “What kid?” Sawyer says "Right, let's get on with it."
As Sawyer and the Man in Black continue, Sawyer asks if the Man in Black reads and tells him that his favorite book is Steinbeck's Of Mice and Men. The Man in Black replies that the book was written "a little after my time." After a brief synopsis of the book, Sawyer pulls a gun on the Man in Black asking what would happen if he put a bullet in the Man in Black's head. The Man in Black says, "Why don't we find out" indifferent to the gun in his face. Sawyer asks him what he is and the Man in Black replies that he is trapped, and has been trapped for so long that he doesn't remember what it feels like to be free. The Man in Black elaborates that he "once was a man" who had normal human emotions, just as everyone does and that he knows what it is like to lose someone he loves. He prods Sawyer to continue following him, because Sawyer is "so close now, it would be a shame to turn back." ♪
The Man in Black and Sawyer arrive at a seaside cliff and the Man in Black indicates that they are to go over the side of it. The Man in Black offers to go first, allaying Sawyer's skepticism, and climbs down a series of wooden and rope ladders. ♪ Sawyer follows, but the ladders give way, perilously swinging him over the cliff side. The Man in Black reaches over, hoisting Sawyer over to the final ladder and saving his life. They come to a shelf in the cliff face and enter a cave.
Inside the cave is a scale, balanced on either side by a white stone and a black rock. The Man in Black removes the white rock and casts it into the sea, referring to it as an "inside joke." ♪ The Man in Black then lights a torch and leads Sawyer into a deeper cavern, where, looking up, he tells Sawyer, "That's why you're here. That, James, is why you are all here." ♪
On the ceiling and walls of the chamber are names scratched into the rock. All names are preceded by a number and most are crossed through. He tells Sawyer that the man who wrote them "was Jacob". Sawyer asks "Was Jacob?" The Man in Black says "He died yesterday" and adds that he's not too upset about the death. He points out that not all of the names are crossed out, at which point Sawyer sees "23 - SHEPHARD" on the wall. The Man in Black goes on to show Sawyer other names on the wall — "8 - REYES," "16 - JARRAH," "42 - KWON" (The Man in Black states that he doesn't know "if it's for Sun or Jin"), and "4-LOCKE," explaining that all of them had been touched by Jacob at some point in their lives before coming to the Island.
When asked about the numbers preceding the names, the Man in Black dismissively says Jacob had a "thing" for numbers.
Upon seeing 15 - FORD on the wall, Sawyer states that he had never met Jacob. The Man in Black explains that, "At some point in your life he came to you when you were vulnerable or miserable, he came to you, manipulated you, pulled your strings like you were a puppet and as a result the choices you thought you made were never really choices, he was pushing you, pushing you - to the Island."
When Sawyer inquires about what it in need of "protecting," the Man in Black insists the answer is "nothing." "That's the joke," he says, explaining, "It's just a damned island."
The Man in Black says that all the people were candidates for Jacob's job. Jacob thought it was his job to protect the island. He then explains that Sawyer has three options:
- "Do nothing. See how all this plays out. And possibly your name will get crossed out" (The Man in Black crosses out Locke's name).
- Take over Jacob's job and protect the Island. (As the Man in Black puts it, "from nothing, there's nothing to protect it from, it's just a damn island").
- "We just go. We get the hell off this Island and we never look back. We do that together."
The Man in Black asks Sawyer if he is ready to go home. Sawyer responds, "Hell yes." ♪
As John Locke parks in his driveway, the wheelchair lift on his van malfunctions, forcing him to roll himself off of the lift at an awkward height. He is unsuccessful and falls out of his wheelchair onto his lawn whereupon lawn sprinklers pop up and soak him. He is noticeably accepting of the circumstance and chuckles at his ridiculous position. Helen rushes from the front door and helps him up. Inside the house, John sits in the bath as Helen speaks on the phone, discussing a wedding. She then talks to John about having their wedding “shotgun style, in Vegas” with just her parents and his father. After finding Dr. Shephard's business card in John's pocket, Helen urges him to contact the spinal surgeon; she says that the two meeting may have been "destiny."
After returning to his desk at the box company, John is confronted by his boss, Randy, who questions him about missing a lunch with Ken Fisher whilst at a conference in Sydney which John lies about attending. Randy reveals he knows John did not attend the conference to which he had been sent and subsequently fires him. In the parking lot, John is unable to get into his van, which he had parked in a regular spot, as opposed to a handicapped spot. He tries to scratch yellow Hummer that blocks his access with the wheelchair lift, but it malfunctions a second before hiting the car. Locke then pounds on the Hummer, causing the car's alarm to go off. Hugo steps out of the building, telling John that he is the owner of the company. ♪ After introducing themselves, John tells Hugo that he has been fired by Randy, whom Hugo calls “a huge douche.” Hugo offers to talk to Randy and make him re-hire Locke, but he declines. Hugo then gives John the number to a temp agency (which he also owns) before telling him that “things are gonna work out.” ♪
At the temp agency, an interviewer asks John what kind of animal he would consider himself and whether he is a "people person." John asks to speak to her supervisor, who turns out to be Rose. John stubbornly requests a job in construction, which Rose responds would not be a good match and that experience is not the issue. She asks him to be realistic, to which John indignantly asks what she knows about being realistic. Rose replies that she has terminal cancer and explains how she had to get past her denial and continue living whatever life she had left. After this, John calms down.
Some time later, John rises in the morning and ponders calling Dr. Shephard as he sits in front of a bathroom mirror. He calls Dr. Shephard's office and the receptionist asks how she may help, but John has a change of heart, saying "you can't help me" and hanging up just as Helen walks in the room. ♪ When she questions him about the phone call, he changes the subject, telling Helen he got fired from his job. Before Helen can respond, an Oceanic courier delivers John's lost luggage.
At the dining table, John admits to Helen that he was fired for lying to his boss and that he didn't go to the Sydney conference. He continues that he instead tried to go on a "walkabout", thus explaining the knives that are in his luggage. He tells her that the organizers of the walkabout wouldn't let him go, and he became very angry, yelling at them "don't ever tell me what I can't do." John then says that he is tired of imagining life without his paralysis and has decided to accept his limitations. He apologizes to Helen, telling her he won't be able to "walk" down the aisle with her and that she shouldn't have to spend her life waiting for a miracle, concluding that there is no such thing (as miracles). Helen says that there are miracles, and reassures him that she loves him no matter the circumstances and was only ever waiting for John, himself. Helen tears up Jack's business card and she and John then embrace. ♪♪
On another day, John is seen working as a teacher at a junior high school. After leading a class of physical education, followed by another where he is to teach about "the human reproductive system," he finds his way to the teachers' lounge, thanks to a student. Within, one teacher rails against his colleagues who do not properly maintain the coffeemaker; Locke diffuses the situation by saying he was hoping for some Earl Grey (tea). The other teacher introduces himself as "Benjamin Linus, European history." Locke smiles intensely at Linus after introducing himself. ♪
- The title of this episode, "The Substitute", has multiple meanings:
- The choice the characters must make, to become a substitute for Jacob or not.
- John Locke becoming a substitute teacher.

- The Man in Black taking Locke's form as a substitute for his previous one.

- The question Locke is asked in his interview as to what animal he identifies with, is one of the interview questions purportedly used by DHARMA as shown in the Mysteries of the Universe.
- Inside the cave, next to the scales holding the black and white stones, there is a stringed musical instrument, similar to a guitar but shaped more like a lute.
- Despite the Barracks' years of neglect, Sawyer's use of the record player indicates the DHARMA Initiative power grid is still intact as of 2007.
- According to the March 11, 2010 podcast, Lindelof and Cuse stated that "Jacob's death [is] very likely to have caused the Man in Black to be stuck in Locke's form."
- For lack of a better description, the Smoke Monster has been described by fans as making "roller coaster noises." In the scene where the camera shows the Smoke Monster's point of view, the cinematography resembles the experience of riding a roller coaster.
- Locke is finally buried after being first seen dead 34 episodes ago in "Through the Looking Glass, Part 2", although his actual body was not seen until "There's No Place Like Home, Part 3". There were 14 episodes between Locke's on-screen death in "The Life and Death of Jeremy Bentham" and his burial.

- Locke's alarm clock noise resembles the beeping of the alarm at the Swan station.
- A photo seen on Locke's desk of Locke and Anthony Cooper is actually a still from the Season 1 episode "Deus Ex Machina".
