Flash-sideways timeline (2004)

6x04 WhoIsJack

Helen questions Locke about Shephard's business card.

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 Jack’s business card in John’s pocket, Helen urges him to contact the spinal surgeon and says that John meeting Jack may be "destiny."

6x04 CallMyPeople

Hugo gives Locke a number for employment.

After returning to his desk at the box company, John is confronted by his boss, Randy, who questions him about missing 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 pounds on the yellow Hummer blocking access to his van, causing the car's alarm to go off. Hurley 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 Hurley calls “a huge douche.” Hurley gives John the number to a temp agency (which he also owns) before telling him that “things are gonna work out.”

6x04 Rose

Rose lectures Locke about being "realistic."

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.

6x04 LovingLife

Locke and Helen decide to not make Locke's condition an obstacle.

Some time later, John rises in the morning and calls Dr. Shephard's office. The receptionist at Dr. Shephard's office answers, but John has a change of heart and hangs up 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" 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 and yelled 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.
6x04 NewFriends

Locke meets the teacher for European history.

He apologizes to Helen, telling her he wont be able to "walk" down the isle at their wedding 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 passionately 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. Within, one teacher rails against his colleagues who do not properly maintain the coffeemaker; Locke defuses the situation by saying he was hoping for some Earl Grey (tea). The other teacher introduces himself as "Benjamin Linus, European history." John introduces himself as "John Locke, substitute." Locke gives an intense "knowing" look after introducing himself.

Original timeline (2007)

Locke's burial

6x04 CollectingAshes

Ilana collects Jacob's remaining ashes.

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 Locke killed Jacob as well. Ilana then asks where Jacob's body is, and Ben tells her that Locke kicked Jacob into the fire and he burned away.

Ilana turns and fills a bag with ash from the now extinguished fire. Ben asks why Locke took Richard and Ilana says that the Man in Black is “recruiting.”

6x04 WhatAboutJohn

Sun, Ilana, Ben and Frank decide to bury Locke.

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 skeptical 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' grave site, 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.
6x04 GoodbyeJohnLocke

John Locke is finally buried in the graveyards.

Ben then asks why the Man in Black wouldn’t just change forms again, and Ilana replies that the 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

6x04 MorningRichard

Richard is released from captivity by 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.”

6x04 HelloCreepyBoy

The Man in Black first sees the mysterious blonde boy with bloody arms in the jungle.

The Man in Black, as Locke, 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 Locke could get close to Jacob because he was a "candidate." Richard appears baffled by this response, and when he prods further, the MIB 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 MIB 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 MIB asks Richard to come with him one final time, insisting that people "seldom get a second chance". When Richard declines again, the MIB, slightly shaken after seeing the boy, walks away saying he will see Richard sooner than he thinks.

6x04 IAmDead

The Man in Black comes to recruit a drunk Sawyer.

The Man in Black walks to Sawyer’s house, from which he hears the song “Search and Destroy” by The Stooges being played loudly. Upon seeing the MIB in Locke's form, the drunken Sawyer says “I thought you were dead.” The MIB replies, "I am."

Sawyer pours a glass of whiskey for the Man in Black and himself. The MIB 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 Man In Black is Locke because Locke "was always scared" while this version of Locke is not. The MIB 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? After some initial reluctance, Sawyer agrees to go along.

6x04 KnowTheRules

The blonde boy reminds the Man in Black about the rules.

As the Man in Black and Sawyer walk through the jungle, the MIB 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 MIB chases the boy into the jungle, eventually falling and looking up to see the boy standing above him. The boy tells the MIB, "you know the rules, you can’t kill him." At this, the MIB 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 MIB, 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 MIB 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 MIB wryly replies “What kid?” Sawyer says "Right, let's get on with it."

6x04 OfMiceAndJames

Sawyer tests the Man in Black's physical boundaries.

As Sawyer and The Man in Black continue, Sawyer asks if the MIB reads and tells him that his favorite book is Steinbeck's Of Mice and Men. The MIB 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 MIB's head. The MIB 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."

6x04 InsideJoke

The Man in Black takes part in his "inside joke" with Jacob.

The Man in Black and Sawyer arrive at a seaside cliff and the MIB 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." MIB 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."


The names and numbers of the candidates.

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 and Sawyer sees "23 - SHEPHARD" on the wall (Flash-back: Jack receives the candy bar from Jacob). The MIB goes on to show Sawyer the names of other survivors — 8 - REYES (Flash-back: Hugo receives the guitar case from Jacob), 16 - JARRAH (Flash-back: Sayid is touched on the shoulder by Jacob at the moment of the fatal car accident that killed Nadia), 42 - KWON (MIB states that he doesn't know "if it's for Sun or Jin") (Flash-back: Jacob congratulates them together at their wedding), and 4-LOCKE (Flash-back: Jacob touches Locke as Locke lies on the grass after being pushed out of the window), — showing that all of them had been touched by Jacob at some point in their off-Island history.
6x04 NoMoreLocke

The Man in Black crosses out Locke's name on the cave wall.

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." The Flash-back shows young Sawyer receiving the fountain pen from Jacob at his parent's funeral.

6x04 SetInMotion

The Man in Black's plan is set in motion.

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:

  1. "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).
  2. Take over Jacob's job and protect the Island. (As the MIB puts it, "from nothing, there's nothing to protect it from, it's just a damn island").
  3. "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."



  • The Man in Black's smoke monster form makes a cameo when it is reflected in the window of Sawyer's Barracks home.
  • In the teachers' lounge at the school where Locke works as a substitute, a wall banner in the background reads: "Live in the present, plan for the future."
  • The title of this episode, "The Substitute", has multiple meanings. It refers to the choice the characters must make, to become a substitute for Jacob or not; John Locke becoming a substitute teacher; Locke's body on Ajira 316 substituting for Christian's on Oceanic 815; MIB taking Locke's form as a substitute for his previous one; etc.
  • The T-shirt Helen was wearing printed with chinese text on left and right side.
    • The text on the left is "精神啟示" which means "revealation to/for spirit".
    • The text on the right is "喚醒的靈魂" which means "awakening soul".
  • Locke uses the same brand of alarm clock as Desmond in "Flashes Before Your Eyes".

Production notes

Bloopers and Continuity Errors

  • When Locke comes back to his office and takes a time to rest, his wristwatch stands still at 11:05:15
  • While Locke contemplates calling Jack's office for the free consult that was offered to him, different versions of Jack's business card are shown.
  • Hurley's Hummer was parked too close to Locke's van, which would not have allowed Hurley enough room to exit his vehicle from the driver's side door.
  • In the final shot when Randy says to Locke "Hey. You're fired." There is a cut that is hardly noticeable but is definitely there. After the cut comes a somewhat out of place salute.

  • Search and Destroy: James Ford is listening to The Stooges' "Search and Destroy." Which contains the lyrics, "I am the world's forgotten boy; the one who searches, searching to destroy," and "I'm the runaway son of a nuclear A-bomb". The lyrics also plead "Somebody gotta save my soul." (Music)
  • Of Mice and Men: James wanted to kill the Man in Black the same way in which George killed Lennie in the novella, after pointing to Steinbeck as his favorite author. This mirrors a conversation about Of Mice and Men that James had with Ben Linus in Season 3. (Books)
  • Allegory of the Cave: The cave that the Man in Black takes Sawyer to can be a reference to this philosophical concept attributed to Plato. The idea that people live their lives and form ideas that are not indicative of reality is mirrored in the Man in Black's view that Jacob manipulated everyone he brought to the Island into believing certain ideas. (Philosophy)
  • Jacob's Ladder: Sawyer and the Man in Black descend "Jacob's Ladder" and arrive at a cave formerly inhabited by Jacob. A Jacob's Ladder has significance in both the Jewish and Christian religions, having many interpretations, among them that it is a bridge between heaven and earth. Saint John Climacus (also known as John of the Ladder) wrote a book called "Ladder of the Divine Ascent" which uses Jacob's Ladder as an analogy for the ascetic life. It is frequently read by Orthodox Christians during the Lent season before Easter. The episode "The Substitute" aired the night before the start of non-Orthodox Lent (Ash Wednesday) (which does not coincide with Orthodox Great Lent). (Religion and ideologies)  (Christianity)
  • Hummer H2: Hurley is shown to own a "Hummer H2" in the flash-sideways timeline when he meets John Locke. (Cars)
  • A Christmas Carol: After the Man in Black confronts James, he claims that James is not so put off by him being there, to which James no longer cares if Locke (as The Man in Black) is dead or if he were the Ghost of Christmas Past. (Books)
  • Tibetan Buddhism: The scale with black and white rocks is part of Buddhist mythology, in which a god called the Dharma-Raja judges the dead using such a scale. (Religion and ideologies)
  • Raiders of the Lost Ark: The music cue when Ilana is placing Jacobs ashes in the pouch is reminiscent of the opening scene from Raiders of the Lost Ark where Indiana Jones is measuring the sand in the pouch to replace the golden idol. (Movies and TV)
  • Star Trek: The Next Generation: In one of his flashes-sideways, John Locke (at the time a bald, wheelchair-bound teacher) asks for Earl Grey tea. Given their fondness for all things science fiction, this was likely a nod on the producer's part to Sir Patrick Stewart, who played both Captain Jean-Luc Picard (who always requested Earl Grey tea and was bald) and Professor Charles Xavier (a bald, wheelchair-bound teacher).

Episode references


Locke mentions his Walkabout tour denying him admission. We return to Locke's cubical and see Randy as his boss for the first time since his original appearance. Randy calls Locke "Colonel." He refers to sending Locke to Sydney on the company's dime, as Rick Romer did. An early scene of Locke looking through the sprinkler's spray echoes his "redemption in the rain" scene from Walkabout's opening.
