Draft:Brian Moser (Dexter)

Biography

Brian was born to Laura Moser and Joseph Driscoll on July 17, 1968. His mother gave birth to a second son, Dexter, on February 1, 1971. They grew up with their mother, estranged from their father, at 1235 Mangrove Drive in Miami, Florida.^[10] Brian was very fond and protective of his brother and he would care for him. On October 3, 1973, four people, including Laura, were found dismembered via chainsaw inside a cargo container at the Port of Miami. Brian and Dexter were present and witnessed their mother being butchered, altering their psyche and shaping them into future killers. Dexter was taken by the Morgan family but Brian was too damaged and was transferred to a psychiatric facility in Tampa.

Psychological issues

As a kid, Brian showed signs of psychopathy, such as killing small animals and showing little emotion to others. Brian was at first taken in with the Morgan family, along with Dexter, but, after attempting to smother their daughter, Debra, and lashing out often, he was deemed too traumatised and taken away. After being sent to and kicked out of various foster homes, he was sent to Harbor Light Mental Hospital, where he was diagnosed with antisocial personality disorder.

Due to seeing his mother being dismembered in front of him, Brian developed an amputee fetish. After eventually stealing the alias, Rudy Cooper, he began working as a prosthetist. According to Brian, his mother lost both her legs in a car accident, and by becoming a doctor he could overcome the feeling of inability of not having been able to help her.

Brian is shown to be capable of masking his true identity, even more so than Dexter (Michael C. Hall), to the point that Debra Morgan (Jennifer Carpenter) begins a romantic relationship with him. Unbeknownst to her, he was only using her to get closer to Dexter and never felt any real emotion towards her. Brian often showed no remorse or guilt when murdering innocent and random people for his benefit.

Modus operandi

Prior to the events of season one, Brian's victims were people who he believed had wronged him in life, such as multiple foster kids who abused him during his stints at their homes. During the first season, Brian mainly killed sex workers. Brian deviated slightly from his pattern during season one, when he killed his father and attempted to kill Angel Batista. Brian usually roamed at night to scour for victims and find a hooker, eventually inviting them to his apartment. When he killed his father and the neighbor, he pretended to be a cable repairman and was able to enter their homes without suspicion.

When his victims arrived at his apartment, Brian would engage in sexual activities with them before putting them in a chokehold to render them unconscious. Brian would strap his victims to a motorized table, located in a custom refrigeration unit inside his apartment. He would use the table to hoist the victim upside-down, then severing their jugular, having them bleed out, and collecting the blood in a bucket. It is revealed that he was hoarding the blood of his victims to use it at a later date in order to stage a blood-soaked crime scene to trigger a traumatic memory of Dexter's. Brian also used methods of suffocation, use of a firearm and insulin injection to kill other victims.

Brian would use surgical tools, such as electrically powered saws, to dismember the victim. He would separate the body into several parts and wrap them in brown paper. He would transport the body parts using a large refrigerated truck, later earning him the moniker "Ice Truck Killer", and take them to specific places. Brian would display the bodies in public, laid out from head to toe.

Season one

Prior to the beginning of the series, three dismembered bodies were found—two in Broward County, and one in Miami—dissected in the same manner, leading to Miami Metro Police suspecting a serial killer. Dexter proposes the idea that the killer is using a refrigerated vehicle to transport the body parts and later encounters one while driving. After he tails the truck, it uses its headlights to obscure Dexter's view and throw the head of a victim onto his car. When Dexter returns to his apartment, he finds the head of a toy doll stuck to his fridge. Dexter sees this as the killer inviting him to play and accepts it. Dexter examines the doll and notices the fingernails are painted. Later, Debra tells Dexter she has found a refrigerated truck with with human fingertips inside, painted the same as the doll's. After Dexter arrives home, he learns that the Ice Truck Killer has been in his house again. When the body of a fourth victim is discovered at an ice hockey arena, CCTV footage captured security guard Tony Tucci (Brad William Henke) leaving the body parts on the rink. Originally thought to be the Ice Truck Killer, Tucci's severed hand is found on a beach, displayed in the same manner as one of Dexter's childhood photos. After leading Dexter to an abandoned hospital, through various clues, he finds Tucci strapped to an operating table, begging for death.

Tucci is later treated by a prosthetist named Rudy Cooper. Debra suggests blindfolding Tucci to gain more insight. When he states that the person who took him captive often used throat lozenges, they return to the hospital to find a wrapper and identify a partial fingerprint from it. Dexter kills a couple that were engaged in smuggling immigrants at a car salvage yard. Later, he is called to the salvage yard's crime scene, where he finds the wife lying in the trailer he killed them in. He deduces that the Ice Truck Killer retrieved the body from the ocean. Worried about being caught, Dexter throws his tools into the ocean; he notices a smiley face etched into one of his blood slides, realising that the killer is not trying to expose him.

After Neil Perry (Sam Witwer) is exposed as the killer, Dexter is saddened that his friend will be put behind bars. However, after a short exchange with Perry, Dexter is relieved to realise he is not the real Ice Truck Killer. Debra begins dating Rudy.^[11] Perry is questioned by Maria LaGuerta (Lauren Velez) and he is let go after he reveals that he pretended to be the killer for attention. Dexter keeps in touch with the killer by sending a message through Craigslist. At his apartment, Rudy opens Craigslist and responds to Dexter's message, revealing him to be the Ice Truck Killer. Dexter learns that his biological father, Joseph Driscoll, has recently died, leaving his house and all his belongings to him. Dexter travels to the house with his girlfriend, Rita Bennett (Julie Benz), and Debra and Rudy show up to help. Driscoll's neighbor, Irma Holt (Jeanette Miller), recognises Rudy to be the cable repairman, who last visited Driscoll. Later after Dexter and his family leave Driscoll's house, Rudy returns as the cable repairman to discreetly kill Holt.

Dexter is called to a crime scene at a hotel room and sees the entire room soaked in blood, triggering a repressed memory. It is surmised that the blood came from at least five bodies. Debra proposes that it is the work of the Ice Truck Killer, as their five victims were bloodless. Angel Batista (David Zayas) speaks to a prostitute, who has a prosthetic hand with fingernails with similar paint of the Ice Truck Killer. Theorizing that the killer is an acrotomophiliac, he speaks to Rudy, unaware he is the actual killer. Rudy later attacks Batista in a parking lot but is elbowed in the face, causing a cut on his lip. After falling out with Debra, he visits her at the station, where they kiss. Rudy tracks down the prostitute that spoke to Batista and kills her, leaving her dismembered body at a Christmas-themed village. Dexter finds out that he is connected to the Ice Truck Killer involving his mother's murder from 1973. Whilst researching past news articles, he discovers one dated October 3 or 103, the number constantly seen at the crime scenes. Rudy convinces Debra to join him on his boat, proposing to her. However, he reveals that he is the killer they have been looking for and strangles her unconscious. Dexter finds out Rudy is the killer after linking the cut on his lip to the blood on Batista's collar.

Dexter rushes to find Debra and finds a picture from Rudy of the cargo container that his mother was killed in. Dexter searches the container at the docks, only to find it full of bananas. Dexter finds a clue that leads him to his childhood home, and has flashbacks revealing that Rudy, whose real name is Brian Moser, is Dexter's biological brother. He reveals to him that they both witnessed their mother's murder, but while Dexter repressed the memory, Brian didn't and was instead put into a mental hospital. Brian talks to Dexter inside their childhood home and tries to persuade Dexter to kill Debra with him, so he can be "free", but Dexter stops him.^[12] Police arrive and Brian escapes through a trap door. At night, Debra appears to be sleeping in Dexter's bed. Brian breaks in and tries to stab her, only to find a fake body in her place. Dexter strangles Brian with a garrote. Dexter takes Brian to his own apartment and straps him to the table he used to kill his victims. After an emotional conversation, Dexter slits Brian's throat, leaving him upside down and staging his death as a suicide.^[13][14]

Dexter goes to the marina, deciding he needs to move forward in order to kill, which, involves letting go of Brian. He removes the doll head from his keychain, his hallucination of Brian fading out.

The Ice Truck Killer case briefly resurfaces when Vince Masuka's (C. S. Lee) intern, Ryan Chambers (Brea Grant), who is obsessed with the case, steals one of Brian's prosthetic arms and sells it online.

Unbeknownst to Masuka, Louis bought the arm and erased all traces of the sale, later shipping it to Dexter.^[15]

As Dexter dumps the body into the ocean, the presence of Brian tries to get him to accept his inner darkness. Dexter visits Kearney, Nebraska after learning the Trinity Killer killed his wife and daughter, confusing Dexter as he knows that he is dead. Brian suggests that Trinity's surviving son Jonah (Brando Eaton) is following his father's footsteps. During the trip, Brian persuades Dexter to be more carefree, leading to him stealing a store clerk's gun and recklessly shooting it around while driving. He meets with Jonah at a hardware store and later confronts him at his house, causing Jonah to flee.

After Dexter leaves his car at a motel, the owner, Norm, becomes anxious when Dexter stumbles upon his marijuana farm. Believing he is working for the government, Norm tries to extort Dexter for money; Dexter hallucinates Brian killing Norm, in reality, it was him. Dexter meets Jonah at the hardware store, where he reveals he that his sister committed suicide and that he killed his mother due to her constant nagging.
