Miles Straume is a spiritualist who was born on the Island in 1977 to Lara and Pierre Chang. At the age of four months, Miles was taken to California by his mother, who was forced to leave the Island by Dr. Chang, due to the danger of the forthcoming energy leak from the Swan. As he grew up, Miles discovered he had a unique ability to extract information from deceased bodies through what he called a "feeling". Many years later, Miles was recruited by Naomi Dorrit to join a science team that would arrive later on the Island aboard the freighter Kahana. He parachuted onto the Island, and was met by the survivors of 815, who didn't seem to trust him or the rest of the science team. Miles' mission on the Island was to capture Benjamin Linus, but he later offered to tell his employer that Ben was dead in exchange for $3.2 million (double what Widmore offered him). When the Island was moved by Ben, Miles and his fellow castaways skipped through time, finally ending up in the 1970s. There, they joined the DHARMA Initiative, which put Miles in proximity with his late parents and, later, himself as a baby. After three years with DHARMA, the Oceanic Six returned and their cover was blown, after which he revealed to his father who he was. Miles assisted Jack with his plan to change the past, saving his father at the Swan construction site in the process. After the detonation of the Jughead bomb by Juliet, he time traveled to his original timeline of 2007 having survived the blast.
Miles was born in March 1977 to Pierre Chang and his wife Lara of the DHARMA Initiative. It is unclear whether Miles was born on the Island or if he was brought there shortly after his birth. At their home at the Barracks, Lara and Pierre would often take turns with the baby Miles in the mornings when he cried, and Chang was known to read to his son at night. At one point, Miles witnessed his father reading to his young self while in the DHARMA Initiative in 1977. ("Because You Left") ("Some Like It Hoth")
Four months after Miles was born, Pierre Chang organised the evacuation of all the DHARMA women and children from the Island, in preparation for the coming Incident by Daniel's warning to Chang before Daniel was killed. Baby Miles and his mother were included in this evacuation. Miles left the Island on the submarine, on his father's strict orders. ("Follow the Leader")
After leaving the Island, Lara and Miles moved to Encino, California in the United States.
As a child, Miles accompanied his mother Lara as she inspected an apartment in Encino, California with the building's landlord. The landlord at first objected to Miles because the neighbors disliked noise, but Lara assured him that Miles is quiet. She gave Miles a quarter for the vending machine, but on the way there he sensed something, causing him to walk toward another apartment. Finding a key, he opened the door and walked inside. Several apartments down, Lara heard her son calling for her, and rushed to the apartment where she found him standing over a man's corpse. Miles claimed to hear the corpse talking.
Several years later, a heavily pierced Miles visited his mother, who was extremely sick and bedridden, and was losing her hair. While his mother was happy to see him, she asked why he had come to visit, as he didn't ever come to visit very often before, and he replied that he wanted answers about the source of his powers and about his father. She replied that his father kicked them out when Miles was just a baby, and had forced them to leave. She didn't tell him explicitly about the DHARMA Initiative or the Island, but she told Miles that his father had been dead for a very long time and that his body was "somewhere [he] could never go." ("Some Like It Hoth")
At a later date Miles became a professional spiritualist, advertising his services to people who wished to communicate with the dead.
Around the time that the supposed wreckage of Flight 815 was recovered, Miles was visiting the house of a woman named Mrs. Gardner in Inglewood, California. Her grandson had been murdered and she wanted his spirit exorcised from her house. Miles agreed to talk to the spirit for a fee, and after he was paid $200 in advance, he entered the boy's former bedroom. There, using a ghostbuster device, he appeared to talk to the spirit, and through it located a stash of money and drugs which the boy had hidden in his room. He took the money and left the drugs. He then went back to Mrs. Gardner, and refunded her $100. ("Confirmed Dead")
Some time later, Miles met with Howard Gray. Mr Gray hired Miles to contact his son, who died in a car accident. Miles' job was to make sure that the son knew that Gray loved him. Miles was apprehensive when he discovered that the son had been cremated, and asked for a larger sum of money, which Gray readily offered. Miles then appeared to contact the spirit of the son and assured Gray that the son was aware of his love. ("Some Like It Hoth")
When Naomi Dorrit and Matthew Abaddon discussed his recruitment, Naomi disparagingly referred to him as a "ghostbuster". ("Confirmed Dead") Naomi approached Miles outside Gray's house and recruited him to work for Charles Widmore. After confirming his ability to gather information from a corpse, she told him that his services would be enlisted in locating a man on an island by communicating with the dead people who reside there. Miles was reluctant until Naomi offered him $1.6 million.
Later Miles was abducted off the street by a group of men in a van. Bram offered Miles information on his father's whereabouts in exchange for not working for Widmore. Miles insisted that he was no longer interested in his father and that they would have to pay him double to refuse Widmore's offer, a sum of $3.2 million. Bram refused to pay him, saying, "All the money in the world isn't going to fill that empty hole inside you." Miles was taken aback at this statement, and his abductors tossed him from the van, warning that he was playing on "the wrong team."
Just before leaving for the Kahana, Miles revisited Howard Gray and returned his money. Miles revealed that he had lied to Gray; he had been unable to make contact with Gray's son. The incredulous Gray asked why Miles couldn't have just continued the lie, and Miles responded that it wouldn't have been fair to the son, and tells the father he should have professed his love to his son before his death. ("Some Like It Hoth")
Before the Kahana left port, Miles indicated that he knew Michael was using a false name without having previously met him. He then added that 80% of the people on the Kahana were lying about something. ("Meet Kevin Johnson")
As Jack, Kate and Daniel approached him, he pretended to be incapacitated, then threatened Jack with a handgun after Jack attempted to examine him. He then informed Daniel that it was the survivors that killed Naomi, and demanded to be taken to her body. During their journey to Naomi's remains, he held Jack and Kate at gunpoint. When Naomi was found, Miles spoke in quiet tones over her body and afterwards confirmed Kate's story about her death.
He behaved aggressively toward Sayid when he was questioned about who he was and what he did. Upon hearing from Frank that Juliet was a "native" of the Island, he became hostile and demanded to know where "he" was. Showing a photograph, Miles said that the team came to the Island to find Ben Linus. ("Confirmed Dead")
Miles, Sayid and Kate took a journey to the Barracks to retrieve Charlotte Lewis from Locke. Upon arriving, they found Hurley tied up in a closet. Hurley told them Locke was losing it and insisted Miles and the others were there to kill them. Hurley asked him if they were, to which Miles replied, "Not yet."
As they continued searching the house, they were ambushed by Locke and Sawyer, who had used Hurley to set a trap. The three captives were taken to different areas of the compound, and Locke and Sayid agreed to trade Miles for Charlotte. ("The Economist")
While at the barracks, Miles used Kate to gain access to Ben. He demanded $3.2 million in exchange for telling his employers that Ben is dead. When challenged that Charlotte already knows that Ben is alive, he said that he will take care of Charlotte. Miles explicitly stated that he knows exactly who Ben is, including the fact that Ben has access to a large amount of money. Kate then attempted to take him back to the boathouse, and he revealed he knows what she's done and who she is. Locke took him back to the boathouse. The next day, Locke put a grenade in Miles' mouth and pulled the pin, forcing Miles to keep his jaws clamped down on the trigger. Locke then left him there. ("Eggtown")
After learning who Ben's man on the boat was, Locke called his group together and retrieved Miles from the boathouse. Miles did not protest when Ben claimed that the freighter team's orders are to kill everyone on the island once Ben is captured. Despite his promise that there would be no more secrets, Locke failed to mention Miles' attempted deal with Ben, which Sawyer questions. Miles laughed at Locke's assertion that Ben would not be able to procure $3.2 million and claimed that Ben would always find a way to get what he wanted. ("Meet Kevin Johnson")
When the Barracks came under attack by Keamy and his men, Keamy gave Miles a walkie to bring to Ben. Miles rang the bell and was let in. He told Ben that Keamy has his daughter. After Keamy killed Alex, Miles showed a look of shock and sympathy. Later, when being rushed out of the house, he showed another look of horror and amazement as the smoke monster attacked Keamy's people. When Sawyer decided he was going to the beach, Miles tagged along. ("The Shape of Things to Come")
On the way, Miles heard the voices of Danielle and Karl, and subsequently discovered their corpses in shallow graves. He claimed that the mercenaries are "not his buddies" and that he "didn't sign up for this." He was also told by Sawyer to stay away from Claire and Aaron, and that he has a "restraining order." After encountering Frank, he, Sawyer, and Claire hid from Keamy. They then continued on after the mercenaries left. Upon taking rest, he witnessed Claire talking to Christian Shephard, and watched her leave. He did not follow because of his "restraining order," however. He informs Sawyer of Claire's departure the next day, and Sawyer finds Aaron, abandoned, crying in the woods. ("Something Nice Back Home")
Miles, Sawyer and Aaron continued their journey back to the beach. Along the way they chanced upon Kate and Jack who were following the chopper inland. Jack asked Kate to take care of Aaron, and take him back to the beach along with Miles. Jack recommenced his trek inland, along with Sawyer. ("There's No Place Like Home, Part 1")
When Faraday started ferrying people off of the Island in the Zodiac raft, Miles stated that he intended to stay on the Island, despite Faraday's warnings. He showed surprise that Charlotte was considering leaving, and then he surprised Charlotte in turn by suggesting that he knew Charlotte had been on the Island before. ("There's No Place Like Home, Parts 2 & 3")
When the island traveled back in time, the beach camp around Miles disappeared, leaving him and several other survivors disoriented. Daniel soon arrived back at the beach, proposing the theory of time travel and suggesting they find a local landmark so that they can get an approximate guess as to when they are in time. Miles traveled with the other survivors to the Swan, where they discovered the crater left by the implosion of the station. When Miles questioned what the station was for, Juliet replied that it was inhabited by Desmond, who spent his time pressing a button every 108 minutes to "save the world," to which Miles responded with some disbelief. After another movement in time, they found that they had traveled to a time before the station was discovered by the survivors. Though he initially wanted to get supplies from the station, Sawyer was convinced by Juliet and Daniel to return to the beach, though Miles was at first reluctant. After the others had left, Miles told Daniel and Charlotte that he thought Juliet was attracted to him before following suit and returning to the beach. ("Because You Left")
At the beach, the survivors worried over ways to survive without fire, shelter, and food. Miles, seeing an opportunity to gain trust, volunteered to hunt for food, and walked off into the jungle unarmed. He returned several hours later carrying the corpse of a boar, claiming he had found it and that it had only been dead for three hours. Shortly thereafter the survivors were bombarded with flaming arrows fired by unseen assailants. Miles was caught by surprise, narrowly dodging several arrows himself before reaching the treeline and safety, though Neil and six other survivors were not as lucky. Miles finally reached safety beyond the treeline. ("The Lie")The next morning, Miles with Charlotte, Daniel, and two unnamed survivors of the beach camp attack traveled to a creek with the intent of rejoining the other survivors. Near the creek, the redshirts triggered claymore mines which exploded, killing them both. A group of Others led by Ellie emerged from the jungle and questioned Miles on the identity of his leader. Miles immediately gestured toward Daniel Faraday. As Ellie and her group marched the three through the jungle, Miles began to sense something and told Daniel that they had just walked over the fresh graves of four U.S. soldiers, three of whom had been shot and one who had died of radiation poisoning. Ellie took Miles and his group to the Others' camp and handed them over to Richard Alpert.
After Charlotte reawakened, the group (Miles, Daniel, Charlotte, Sawyer, Juliet and Locke) decided to head back to the beach and use the Zodiac in order to get to the Orchid faster. Later the same day Miles informed Daniel that he had also suffered a nosebleed, a symptom which Daniel told him relates to the duration of exposure to the Island. This confused Miles, who pointed out that the survivors (who had not shown any symptoms to this point) had been on the Island for months before the freighter arrived. Daniel asked Miles if he was sure he had never been to the island before. Miles, along with Juliet, Sawyer, Charlotte, Daniel, and Locke, found two outriggers at the beach camp. Miles helped the group paddle the outrigger into open water, where the group was chased and shot at by unknown pursuers in the other outrigger. After another time flash, the group successfully came ashore during a rainstorm. ("The Little Prince")
Miles traveled with the group into the jungle and they experienced another time flash just before discovering Jin. After everyone greeted Jin, they resumed traveling towards the Orchid station. After walking for awhile, the group experienced a few flashes in rapid succession. After the fourth flash, Charlotte collapsed, unable to go on. Miles decided to go with Locke, Juliet, Sawyer and Jin to the Orchid, leaving Daniel to look after a dying Charlotte. Although the Orchid disappeared following a time flash, the group discovered a nearby well which, according to Charlotte, would help them. As Locke descended into the well using a rope held by Sawyer, another time flash occurred. Miles told Sawyer he could "let go of the rope now," as they realized that they had moved to a time period in which the well did not exist. ("This Place Is Death") When Juliet commented they were now before the well was built, Miles added "I'd say way before" and pointed out a statue in the distance. ("LaFleur")
Miles, along with Sawyer, Juliet, Jin, and Faraday, time traveled to 1974 after Locke moved the frozen wheel. When Sawyer suggested heading back to the beach, Miles disagreed. Juliet then backed Sawyer up and Miles irritatedly stated that going to the Orchid and going to the beach were the "only two plans you people have". After being captured by the DHARMA Initiative, the group pretended to be victims of a shipwreck and they integrated themselves into the Initiative. ("LaFleur")
Within the first week of joining, Miles realized that he had personal connection with the Initiative when his mother stepped behind him in the cafeteria lunch line. Realizing that both his parents lived on the Island, Miles ignored them as best he could and continued with the lie set forth by Sawyer. ("Some Like It Hoth")
As of 1977, Miles was working in the DHARMA security division under the command of his new boss, Sawyer, who had become Head of Security using the alias "LaFleur". When a drunken Horace Goodspeed began blowing up trees with dynamite near the Flame, Miles and Sawyer recovered him and cleaned up the mess. ("LaFleur")
Two days later, LaFleur assigned Miles to guard Jack, Kate and Hurley, after young Ben was shot and nearly killed by Sayid. While guarding them, he and Hurley had a lengthy debate about the effects and paradoxes of time travel, forming a friendship in the meantime. ("Whatever Happened, Happened")
Some time later, LaFleur called Miles and asked him to "accidentally erase" one of the tapes from the fence security cameras. While he was preparing to do this, he was approached by Horace, who tasked him to take something out to Radzinsky in a Hostile-controlled area and receive something in return. It became obvious that this "something" was the corpse of a DHARMA worker who had died under mysterious circumstances. After Radzinsky and his workers disappeared, Miles moved to the corpse in the back of his van and asked him, "What really happened?" He learned that the man, Alvarez, had a filling which ripped from his mouth and exited through his brain.
When Miles returned to Horace, he was told to bring the body to Dr. Pierre Chang at the Orchid. Miles was joined by Hurley on his journey, who discovered the body in the back of the van. Confronted, Miles told him what really happened to the body. To his bewilderment, Hurley completely accepted Miles story, noting he also talks with the dead, and sometimes plays chess with them. Miles said that isn't how it works, at which point Hurley responded that Miles admitted to his ability. Miles explained that he is able to get a "feeling" about who the deceased was and whatever they knew before they died.
At the Orchid, Miles revealed to Hurley that Dr. Chang was his father. Miles and Hurley then gave Dr. Chang a ride to the Swan station construction site. Along the way, Hurley kept dropping hints about the relationship between Miles and Pierre, which upset Miles, who had never known his father. On the way back, Hurley told Miles about his own troubled relationship with his father, and how he forgave him. He suggested Miles try to gain a relationship with his own father.
At night, an emotional Miles saw his mother, father, and his three-month-old self in a window, but chose to walk away. However, after his father was handed a phone, Pierre came outside and, noticing Miles on the walkway, asked for his help in picking up a group of scientists from Ann Arbor at the submarine dock. Miles was surprised to find out that one of those scientists was Daniel Faraday. ("Some Like It Hoth")
Daniel told Miles that the reason he had returned was that he had discovered that the members of the Oceanic Six were somehow back on the island. Faraday then ordered Miles to take him to Jack's house. After Daniel and Jack had a talk, Miles drove Faraday to the Orchid. While Daniel was at the station, Miles waited above. Daniel then returned, along with Pierre Chang. Miles witnessed as Daniel revealed that he was from the future. Miles tried to intervene, but Daniel told Chang that Miles was his son. Chang asked Miles if it was true, but Miles denied it. Miles then drove Daniel to Sawyer's house, where Daniel revealed that he needed to meet with his mother, who was with the Hostiles. After Juliet revealed to the group the code to the sonic fence, and Kate agreed to show the way, Miles gave Daniel the keys to the jeep.
Meanwhile, Sawyer ordered everyone to prepare for leaving to the jungle, as Phil had discovered the tape that showed Ben's delivery to the Hostiles. This was the tape which Miles failed to erase earlier. ("The Variable")
Now under serious suspicion, Miles, Hurley and Jin escaped from the Barracks, heading for the beach. Chang followed them and asked the three if they were really from the future. Hurley denied it at first but gave the truth away when he couldn't answer a question about the current U.S. President. Chang believed them and then asked Miles if he really was his son, and Miles reluctantly affirmed that he was.
Back at the Barracks, Chang was now having people evacuated, after learning of the upcoming Incident. Miles, Hurley, and Jin watched Charlotte and her mother get out of a bus and head for the dock. Lara and baby Miles also got out. Miles saw his parents argue as Pierre demanded they evacuate the Island on the sub. Through watching these events Miles realized that his father had to be harsh to his mother in order to save her life. Miles then saw Juliet and Sawyer, handcuffed and being brought to the dock in a jeep. A confused Miles handed his binoculars to Hurley, who told Miles that Sawyer probably had a plan. ("Follow the Leader")
A few hours later, Miles joined Hurley and Jin in saving Jack and a wounded Sayid from attacking members of the DHARMA Initiative by picking them up in a DHARMA van. At Jack's urging, Hurley proceeded to drive the van to the Swan construction site. Miles questioned Jack's plan to detonate a nuclear device, and stopped with the rest of the group when they encountered Kate, Sawyer, and Juliet, and expressed doubt as to whether Sayid would recover from his wound. A short time later, Jack set out with the bomb to the Swan site, and Miles questioned the rest of the group as to whether or not they had considered that Jack's detonation of the bomb would cause the Incident rather than prevent it. Immediately after he asked this, the group spotted a group of DHARMA Security personnel led by Phil driving to the Swan. In an attempt to save Jack, Miles accompanied the rest of them to the Swan construction site, and took part in a firefight in an attempt to save Jack and allow him to detonate the bomb. His father was present at the site, and attempted to turn off a construction drill which was on the verge of reaching an electromagnetic pocket of energy with no success. After killing or neutralizing all of the DHARMA personnel present at the site with the exception of Pierre Chang, who aided them by holding Radzinsky at gunpoint, Miles witnessed Jack drop the bomb down the drilling shaft, with no immediate effect. Shortly after, an electromagnetic incident occurred which pulled all metal objects toward the shaft, and Chang's hand was crushed and pinned under a steel beam. Miles lifted the beam, saving his father's life, and -- finally referring to him as "Dad" -- urged him to get as far away from the site as possible. A few moments later, the bomb was detonated by Juliet, who had fallen to the bottom of the shaft. ("The Incident, Parts 1 & 2")
A time flash transported Miles and the rest of those from his time period to 2007. He was the first to encounter Kate in the jungle and rejoined the rest of the group as they tried to recover Juliet from the imploded Swan station. After Juliet's death, Sawyer asked Miles to help dig her grave. Following the burial, Sawyer forced Miles to speak to the deceased Juliet and find out what she was about to reveal before she died. Miles entered a trance, then stated that Juliet's message was "It worked." There was no further elaboration on what that meant. Later, Miles and Sawyer were captured by a group of Others and taken to the Temple. There, Miles sat with Hurley near Sayid's dead body. Hurley tried speaking to his dead friend and noticed Miles looking at him strangely. Miles stated that it was "nothing." Shortly thereafter, Sayid returned to life. ("LA X, Parts 1 & 2")
