Season one By the start of
season one, Dexter is a
blood spatter analyst for the Miami Metro Police Department; in his "secret life", he is a serial killer who preys on people who are themselves murderers. In his private life, Dexter maintains superficial relationships – with his sister
Debra (
Jennifer Carpenter), his girlfriend
Rita (
Julie Benz), and Rita's children,
Astor (
Christina Robinson) and
Cody (Daniel Goldman in season one,
Preston Bailey in subsequent seasons) to appear normal. Dexter has internal conversations with his late foster father,
Harry Morgan (
James Remar), who gives him advice about killing and navigating his personal life. Rita's previous, abusive marriage leaves her afraid to have sex, which suits the
asexual Dexter perfectly. When she overcomes her demons and becomes more amorous, however, Dexter considers ending the relationship, fearing that she will see him as he really is if they become a real couple. However, during a therapy session with one of his intended victims, psychologist Emmett Meridian (
Tony Goldwyn), Dexter is put into a state of deep relaxation, wherein he sees a frightening image of a small boy sitting in a pool of blood. In a heightened emotional state, he runs to Rita's house for comfort, and they have sex. His research leads him to discover he witnessed his mother's murder as a child, and he had a brother named Brian. Eventually, the Ice Truck Killer (who turns out to be Rudy) kidnaps Debra after proposing to her, then drugs her and takes her to Dexter's childhood home. When Dexter goes to rescue Debra, he finally recognizes Rudy as his long-lost brother, Brian Moser. Brian proposes that they begin to murder together, and leads Dexter to a bound and drugged Debra, suggests that she be their first kill. After wrestling with internal conflicts from his attachment to his biological brother and need to protect his adoptive sister, Dexter ultimately decides that his loyalty lies with Debra. Later on, Brian begins to hunt down Debra himself, but Dexter apprehends Brian and then ties him down to an operating table in Brian's apartment. Dexter tearfully slits Brian's throat, staging the crime scene to make it look like Brian committed suicide. Eventually, the police find the body and close the case. The season ends with Dexter wondering what it would be like if everyone knew his secrets and imagining being celebrated outside the police station by an adoring crowd. The two men grow closer, and Dexter even makes Prado his best man. Prado gradually discerns that Dexter is a serial killer, and they begin to murder together according to Dexter's "code". When Prado deviates from the code to murder a rival defense attorney, it sets off a game of competing leverage and blackmail between the two men. Dexter discovers the blood on the shirt is actually bovine, meaning that Prado was just using him as an excuse to kill. Angry and hurt, Dexter decides to kill Prado. Dexter then kills Prado and marries Rita, with Debra as his "best man". After being tipped off by Prado, a serial killer called "the Skinner" (
Jesse Borrego), who is searching for Freebo, kidnaps Dexter on Dexter's wedding day. Facing certain death, Dexter resolves to keep fighting so he can live to see his son; he frees himself and kills the Skinner by snapping his neck and throwing his body into an arriving police car. During the course of the season, Dexter justifies killing two people who do not fit his code: Nathan Marten (Jason Kaufman), a
pedophile who is stalking Astor; and his old friend Camilla Figg (
Margo Martindale), who is dying of cancer and asks him to end her suffering.
Season four played the antagonist in season 4 At outset of
season four, Rita has given birth to a baby boy, Harrison. Dexter is happy to have a child of his own, but his responsibilities as a new father leave him too exhausted to kill. Dexter finds it increasingly difficult to keep concealing his secret life, which leads to conflict with Rita and Astor, who has entered
adolescence. At Rita's urging, Dexter and she enter
couples therapy. While driving home after killing his first victim in months, Dexter falls asleep at the wheel and has an accident, and the resultant short-term memory loss causes him to forget where his victim's body is. During his pursuit of Trinity, Dexter targets a photographer, Jonathan Farrow (
Greg Ellis) who is accused of murder, targeting him after he seemingly threatens Debra. He acquires proof that indicate that Farrow killed the models he took photos of, before capturing and killing Farrow in his own photography studio, despite Farrow's adamant protests that he did not kill anyone. The next day, Dexter learns that it was in fact Farrow's assistant that had been killing the models, and he is left shaken by the knowledge that he has unintentionally violated his code. When he returns home, Dexter makes arrangements for Rita and him to take a belated honeymoon. He sends Rita ahead and entraps Mitchell, who is trying to skip town. Before Dexter kills him with a hammer, Mitchell tells him that Dexter will not be able to control his violent urges for long, and that "it's already over"—the same thing Mitchell tells his victims just before killing them. After returning home, Dexter calls Rita's phone to find out if she and Harrison made it alright. He immediately hears Rita's phone start to ring, indicating that she is in the house. Harrison then starts crying and Dexter is devastated to find Rita lying dead in the bathtub, with Harrison on the floor in a pool of his mother's blood; she was Trinity's final victim.
Season five The
fifth season opens with a shocked, guilt-ridden Dexter clutching Harrison as the police respond to his call, in which Dexter says "It was me". While he means that he killed her by letting Mitchell know his identity, the police interpret this as an admission of direct guilt. The FBI, however, soon clear Dexter, as he was with the police at Mitchell's house at the time Rita was murdered. Dexter spends the next day completely numb, unable to even fake any sort of emotion or grief. As Dexter plans to disconnect and restart, he finds himself confronted by Rankin (
Brad Carter), a brash, foul-mouthed hillbilly. When Rankin insults Rita, Dexter kills him in a fit of rage. Harry tells Dexter that this act is the first human thing he has seen Dexter do since Rita's death. Dexter escapes Debra's watch long enough to dispose of Ray Speltzer (
Matt Gerald), a brutal serial killer who had evaded prison on a technicality, and Debra comes to understand why Dexter kills. She makes a deal with him: she will not stop Dexter as long as he does not tell her about it or interfere with Miami-Metro investigations. Dexter sets his sights on killing
Hannah McKay (
Yvonne Strahovski), a serial poisoner, who as a teenager had gone on a cross-country killing spree with her boyfriend. Dexter subdues her and prepares to kill her, but stops when Hannah does not appear to fear him. They are both suddenly overcome with attraction and have sex. Dexter falls in love with Hannah, who helps him realize that his "Dark Passenger" does not control his life. Dexter's romance with Hannah complicates his relationship with Debra, however. Debra is intent on arresting Hannah for the murder of Sal Price, a crime writer for whom Debra had feelings, and Dexter has trouble reconciling his feelings for his girlfriend with his responsibility to his adoptive sister. To make matters worse, Miami-Metro Captain
María LaGuerta (
Lauren Velez) discovers a blood slide containing the blood of serial killer Travis Marshall at the scene of his death. Recognizing similarities to the Bay Harbor butcher's methods, she begins an investigation to determine if the butcher is still alive and seeks to prove Doakes' innocence. Her suspicions turn toward Dexter when she learns about his boat's relocation during the Butcher investigation. LaGuerta reopens the Bay Harbor Butcher case, convinced that Doakes was innocent and that Dexter is hiding something. When Dexter tries to kill Hector Estrada (
Nestor Serrano), the man who ordered Dexter's mother's murder, LaGuerta arrives at the scene, forcing him to let Estrada go so he can escape. Dexter deduces that LaGuerta had orchestrated Estrada's release from prison to set Dexter up. At the beginning of the season, mobster
Isaak Sirko (
Ray Stevenson) vows to kill Dexter to avenge his lover, Viktor Baskov (
Enver Gjokaj), a cop killer and one of Dexter's victims. Fearing for his family's safety, Dexter engineers Sirko's arrest, but Sirko is soon released on bail and resumes his vendetta. Sirko asks for Dexter's protection against his former associates, who fear that he will testify against them; in return, he promises Dexter that he will let him live. Dexter refuses, but ends up inadvertently coming to Sirko's aid when one of his former henchmen attacks them both. Dexter kills the mobster, but is too late to save Sirko, who is mortally wounded during the struggle. As he dies, Sirko reassures Dexter that he can still find happiness. Debra gets into a near-fatal car accident following a confrontation with Hannah, and insists to Dexter that Hannah poisoned her. Dexter refuses to believe it at first, but he is suspicious enough to order a
toxicology screen on Debra's water bottle. To Dexter's horror, the results prove that Hannah had spiked Debra's water with an overdose of
Xanax. Left with no other choice, Dexter gives Debra proof that Hannah murdered Price and looks on, heartbroken, as Debra arrests her.
Season eight The
eighth season opens six months later, with Dexter growing increasingly worried about Debra, who has quit the police force and spiraled into depression and self-destructive behavior. Dexter goes to her new job as a private investigator and learns that Debra is pursuing, and sleeping with, drug dealer Andrew Briggs (
Rhys Coiro). When Dexter confronts her, Debra tells him that she wishes she had killed him instead of LaGuerta. A few days later, Dexter learns that an assassin, El Sapo (
Nick Gomez), is going to kill Briggs and Debra, and Dexter goes to Debra's hotel to save her. A scuffle ensues, in which Dexter kills Briggs. He begs Debra to come with him, but she refuses. Soon afterward, El Sapo is found dead, and Dexter is called in to investigate. He discovers that some of the blood at the scene belongs to Debra. She admits to killing El Sapo, and Dexter reluctantly covers up the crime. Dexter meets Dr. Evelyn Vogel (
Charlotte Rampling), a
neuropsychiatrist consulting with Miami Metro about a serial killer dubbed "the Brain Surgeon" who removes parts of his victims' brains. Vogel, a specialist in the
neuropathology of
psychopaths, tells Dexter that she knew Harry, and helped him to invent Dexter's "code" because she believes that psychopaths can play useful roles in society. Vogel says the "Brain Surgeon" is one of her former patients, and asks Dexter to kill him before he goes after her. Dexter starts looking into another of Vogel's former patients, serial killer A.J. Yates (
Aaron McCusker). He saves one of Yates' victims and confronts the killer, who escapes. The following day, Debra asks Dexter to take a drive with her so they can talk. During the drive, she intentionally crashes the car into the bay, intent on killing them both. Debra survives, however, and saves Dexter's life. When Yates kidnaps Vogel, the two of them put aside their differences to track him down. Dexter kills Yates to keep him from harming Debra, and he and Debra reconcile. Dexter sets his sights on a new victim: Zach Hamilton (
Sam Underwood), a teenager from a wealthy family who murdered his father's mistress and is now preparing to kill his father. Dexter kidnaps Zach, who admits that he enjoys killing and will do it again. Seeing in Zach a kindred spirit, Dexter promises to teach him how to kill without getting caught. When Dexter's neighbor Cassie Jollenston (
Bethany Joy Lenz) is murdered, he at first believes Zach is responsible and decides to kill him. Dexter confronts Zach, who swears that he did not target Cassie, but another murderer, giving Dexter hope that Zach can be "trained" after all. That hope is dashed, however, when Dexter finds Zach's dead body in his apartment — with a piece of his brain missing. Hannah reappears in Dexter's life when she non-lethally poisons him and Debra to get his attention. The night before Hannah leaves, however, Dexter and she have sex, and he realizes that he is still in love with her. They renew their relationship, and plan to run away together to
Argentina. After investigating, Dexter discovers that Zach's killer is Vogel's blood relative. Vogel tells Dexter that she had a son, Daniel, who as a teenager murdered his younger brother Richard before apparently dying in a fire. Dexter discovers that Daniel set the fire himself to fake his own death, and that he is now living under the identity of Oliver Saxon (
Darri Ingolfsson)—Cassie's boyfriend at the time of her murder. Dexter suspects that Saxon is the "Brain Surgeon" and warns Vogel, who tells him to stay out of it; Dexter is unaware that she is sheltering her son. Days later, Saxon shows up at Dexter's apartment and offers a truce: he will spare Dexter's family if Dexter will leave him alone. Dexter pretends to accept, but is now more determined than ever to kill him. He finds proof of Saxon's murders, which he turns over to the police so that Saxon will be forced to come after him before he leaves Miami. Dexter then enlists Debra's help in subduing Saxon and prepares to kill him. At the last moment, however, Dexter realizes that his love for Hannah is stronger than his need to kill, and he spares Saxon's life. He calls Debra so she can arrest Saxon, and says his goodbyes to her and Harry. After he leaves, however, Saxon escapes his bindings and shoots Debra in the stomach. In the series finale, "
Remember the Monsters?", Dexter's flight to Argentina is delayed by a hurricane, and he tells Hannah and Harrison to go on without him, intending to take care of Saxon. When he learns what has happened to Debra, Dexter rushes to her side at the hospital, but she tells him to go on and live a good life. Moments later, however, she suffers a major stroke that leaves her in a
persistent vegetative state. Dexter blames himself, and realizes he will always destroy those he loves; he sees at last he can never have a happy life. After Saxon is arrested, Dexter kills him in his cell, and apparently convinces Quinn and Batista that he acted in self-defense (it is implied that they knew what really happened). Dexter goes to see Debra one last time, tearfully turns off her life support, and buries her at sea. He then fakes his own death by wrecking his boat. The series' final scene reveals that he has assumed a new identity in Oregon as a lumberjack and begun a new life, alone. Caldwell is officially considered a missing person, and his father Kurt (
Clancy Brown) begins nosing around the investigation. Dexter destroys the corpse and alters the crime scene to make it look like Matt left town after being injured. That night, he runs into Kurt, who drunkenly claims to have gotten a
FaceTime message from his son. Unbeknownst to Dexter, Kurt is a serial killer who preys on runaway teenage girls, and is trying to get the search called off so the police will not find his victims' bodies. At the same time, a now teenage Harrison (
Jack Alcott) comes back into Dexter's life, having tracked him to Iron Lake. He says he lived in a series of foster homes after Hannah died of
pancreatic cancer. Harrison also causes Dexter to depart somewhat from his "code"; when Harrison nearly dies of a
fentanyl overdose at a party, Dexter murders the drug dealer who sold him the pills by forcing him to ingest a lethal amount of the drug instead of his usual killing method, a stab wound to the chest. Harrison is injured in a knife fight with another student, Ethan Williams (Christian Dell'Edera), whom he badly wounds. Harrison claims that Ethan told him he was planning a
school shooting and stabbed him, and that he stabbed Ethan back in self-defense. When it is discovered that Ethan was indeed planning to kill several of his classmates, Harrison is hailed as a hero, but Dexter doubts his story. Using his training as a blood spatter analyst, Dexter reconstructs the fight and determines that Harrison stabbed Ethan unprovoked, and then inflicted a superficial stab wound upon himself to make it look like Ethan attacked him. Dexter searches Harrison's room and finds a bloody straight razor—the same kind of blade that Arthur Mitchell used to kill Rita—and realizes that his son has inherited his homicidal tendencies. During a chance meeting with Angel Batista (now Captain of Miami Metro) at a police conference in New York City, Angela learns about Dexter Morgan's supposed death, and after some investigation discovers the true identity of "Jim Lindsay". When Angela finds the mummified corpse of her friend Iris, who disappeared 25 years earlier, she asks Dexter to analyze the remains, and tells him that she suspects Kurt of killing her. Dexter leads her toward investigating Kurt as a serial killer in hopes that exposing his crimes will destroy his influence over Harrison. She arrests Kurt for Iris' murder, but Kurt surprises her by saying that his late father, Roger, committed the crime. (A flashback reveals that Kurt did indeed kill her, however.) When Kurt is released, he tries to intimidate Dexter by hinting that he knows he killed Matt, and Dexter realizes that he will have to kill Kurt to protect Harrison and himself. Kurt pays one of his truckers, Elric Kane (
Shuler Hensley), to kidnap Dexter so he can kill him and Harrison, but Dexter manages to evade and kill him. Dexter arrives at Kurt's cabin just in time to save Harrison from Kurt, who runs off. He tells Harrison that they have the same "Dark Passenger", and for the first time truly bonds with his son. At first, Dexter tells Harrison that he merely "confronts" murderers to make them stop killing, but Harrison eventually figures out that Dexter kills his victims. Harrison reveals that he remembers seeing Mitchell kill Rita, and that he has been consumed with a violent rage ever since. He then says that Kurt deserves to die, and father and son set out to kill him. Together, they find Kurt's victims, including Park, perfectly preserved and displayed in a bunker underneath his house. Dexter intentionally triggers an alarm to let Kurt know they found his hiding place. As intended, Kurt rushes back to his house, where Dexter incapacitates him and prepares a kill site in Kurt's own bunker. When Kurt claims that he "saved" his victims from lives of pain and suffering, Dexter kills him as Harrison watches, and resolves to teach him "the Code of Harry". They return to Dexter's cabin to find that Kurt had burned it down the night before. They stay with Angela and Audrey, now Harrison's girlfriend, and start to bond as a family—until Angela finds evidence, left by Kurt, exposing Dexter as Matt's murderer. She then sees a connection between that proof and new evidence uncovered by Park on the Bay Harbor Butcher case, and realizes that Dexter is the killer.
Dexter: Original Sin The first episode of the prequel series
Dexter: Original Sin, which portrays a young Dexter's evolution into a serial killer, reveals that Dexter is taken to a hospital after Harrison shot him, and that he briefly dies in surgery but emergency room doctors manage to revive him as he begins narrating his life as it flashes before his eyes. The series portrays Dexter in his early 20s, living with Harry (
Christian Slater) and the teenage Debra (
Molly Brown) a year after Harry's wife Doris (Jasper Lewis) died of cancer. As in the novels and original TV series, Harry teaches Dexter how to kill people who "deserve it" without getting caught, beginning with a nurse (
Tanya Clarke) who is killing her patients with morphine overdoses. The series also portrays Dexter beginning work at Miami Metro as an intern and first meeting Maria LaGuerta (
Christina Milian), Angel Batista (
James Martinez), and Vince Masuka (
Alex Shimizu).
Dexter: Resurrection Taken to the hospital after his shooting, Dexter is left in a coma for ten weeks in which he encounters visions of various people encouraging him to live. After awakening, Dexter undergoes extensive physical therapy to recover from his injuries and learns from Teddy Reed that Matt Caldwell's death was ultimately blamed on Kurt while Logan's was ruled to be self-defense after the bullet hole was found in Dexter's cell. Angela backtracked on Dexter being the Bay Harbor Butcher and left town, but leaves Dexter a message ordering him to leave Iron Lake and implying that her recanting is repayment for Dexter solving the murder of Angela's friend Iris. Dexter is reunited with Angel for the first time in ten years who legally resurrects Dexter, but his former best friend is now suspicious that Dexter truly is the Bay Harbor Butcher. Dexter later learns of a murder in New York City matching his MO and the Code of Harry and realizes that Harrison is the culprit. Stealing the car of another patient who had died of a heart attack, Dexter heads to New York to find his son. In New York, Dexter keeps his distance from Harrison while protecting him. Reclaiming his identity as Dexter Morgan, he rents an apartment and gets a job as a
rideshare driver although Dexter remains in a weakened state from the shooting. Learning of a serial killer going by the Dark Passenger, Dexter resumes his killing spree once again. However, in a surprising turn of events, Dexter is revealed to have grown to care about other people to the point that he again prioritizes saving the killer's next victim over getting his target, something he did in the original series without much reflection on it. This allows the Dark Passenger to escape in Dexter's weakened state, but without hurting anyone. Dexter eventually moves into a basement apartment with his new friend, fellow rideshare driver, Blessing Kamara. He continues his hunt for the Dark Passenger killer and successfully kills him, but in doing so, discovers an invitation to a serial killer group arrange by local billionaire Leon Prater. Dexter goes to Prater’s meeting undercover as “Red Schmidt”, the Dark Passenger, and contemplates killing the other serial killers. He eventually kills Lowell, a serial killer who takes tattoos as trophies. When Harrison is about to turn himself in for the murder of Ryan Foster, Dexter stops him, and the two reunited, though Harrison is still suspicious of Dexter and doesn’t want a relationship with him. Dexter, realizing Harrison may be arrested for the murder anyway, frames another serial killer in the club, Lady Vengeance for Ryan Foster’s murder. As Ryan Foster was a sexual abuser, and Lady Vengeance went after predators, the media and police buy this narrative. By this point, Angel Batista is hot on the trails of both Dexter and Harrison and has gone to NYPD Homicide Detectives Melvin Oliva and Claudette Wallace about his suspicions. Batista goes with Wallace and Oliva to interview Lady Vengeance in prison, but they find her dead in her cell, the murder having been arranged by Prater and his security consultant, Charley. NYPD mostly dismiss Batista’s suspicions, but Wallace does further research into Dexter’s backstory. Meanwhile, Dexter is still undercover as Red Schmidt at Prater’s meeting, and takes an opportunity to kill the Gemini Killer inside Blessing’s house. At another gathering, he realizes that the Gemini Killer was actually two killers, twins, and tricks the second into attacking him, leading to Dexter killing the second in front of Prater, Charley, and remaining group member, Al, who Dexter tries to kill later on, but he manages to evade him. Charley becomes increasingly suspicious of Dexter, and while eating at a restaurant with Harrison, Prater confronts Dexter and tells him he is upset that he has not shared more of his past. Dexter is angered by Prater’s intrusion into his personal life, and when Charley holds Harrison at gunpoint later that day, Dexter vows to take them out. He makes an appointment to privately meet with Prater. Batista, meanwhile, has photographed Dexter meeting Prater, and believing Prater, a billionaire associated with law enforcement may be Dexter’s next victim just like Batista’s coworkers Doakes, LaGuerta, and Debra Morgan were (although Dexter did not kill them, Batista does not know and believes he is responsible), Batista meets with Prater and reveals Dexter is the Bay Harbor Butcher. Prater, being a fan of serial killers, is ecstatic to learn Dexter is the Butcher, and questions him on the fact that James Doakes has now taken all the credit. Prater tells Dexter he will finance his murders and bring nation wide serial killers to New York for Dexter, but the entrance fee will be killing Batista, whom Prater has tied to the table, unbeknownst to Prater, on which Dexter killed his brother, the Ice Truck Killer, Brian Moser. Although Dexter considers killing Batista due to the threat he poses, especially now that Batista knows the truth beyond a shadow of a doubt, Dexter chooses to cut his former friend loose in the hopes of them working together one last time. In a rage, Batista attacks and strangles Dexter, only to be fatally shot by Prater. Unable to help Batista, Dexter admits to his friend that he's the Bay Harbor Butcher, but he didn't kill LaGuerta and Doakes. Batista lays the blame for their deaths and his own at Dexter's feet and with his last words, curses Dexter's name. Despite their differences, Dexter is shown to be enraged and devastated at Batista's death. Dexter is left trapped in Prater’s vault, but manages to use Batista’s phone to call Harrison, who manages to free him. Dexter finds Prater’s files on Charley, and reveals their existence to her, causing Charley to abandon Prater. Meanwhile, Prater is throwing a massive gala, and is high on having committed his first murder. He eventually catches up with Dexter and ends up holding Harrison at gunpoint, but Harrison neutralizes him with M-99. Harrison leaves Prater’s gala. Dexter then kills Prater on the Ice Truck Killer’s table, bagging his body and taking his blood slides, which Prater had purchased from the FBI, and several files on various serial killers. Dexter then uses an alarm to alert the police at the Gala of the crime scene in Prater’s vault. Batista’s body is removed from the scene, while Dexter hijacks Prater’s yacht and dumps his body into the ocean. Dexter chooses to stay in New York City with Harrison and Blessing. ==Other formats==
