Louis Greene is a Character on Showtime's DEXTER.

He is Vince Masuka's third lab intern. He is a technological wiz, having expertise in gathering information and is even capable of hacking certain websites. His fascination with Dexter Morgan borders on obsession.


Louis is a slender man with short, brown hair and blue eyes. He is sometimes seen with facial hair.

His work attire ranges from subtle lab coats to more suburban styles, closely fitting a "hipster" look. His casual clothes consist mostly of T-shirts and jeans. 

In his penthouse apartment are various collections of games, toys, models, and artwork, showing that he has unique personal tastes. 


Louis is what some might call a "nerd." He spends most of his time on his computer designing video games or selling collectibles. His job as a lab intern allows him to "research" for his next big title - Homicidal Tendencies, a video game about serial killers.

Besides his forensic work in Miami Metro Homicide, he uses his abilities to hack information when a technological professional is needed. In several instances, he helps Lieutenant Debra Morgan grow closer to catching DDK (the Doomsday Killer).

His relationship with Vince Masuka is friendly and helpful. After the Prosthetic Arm is stolen by Ryan Chambers and sold online, Louis wipes out the event across the internet to protect Masuka and the department. Masuka is relieved, even though Louis couldn't retrieve the purchased arm.

Louis is starstruck by Dexter Morgan due to his fascination with Dexter's expert blood-spatter work. In his first approach to Jamie Batista, he asks her whether Dexter is "as cool at home as he is at work." Later, Louis grows to hate Dexter because he scorned the video game that he worked on for five years.


Although Louis Greene doesn't personally appear until "The Angel Of Death," these events lead up to his introduction.

Vince Masuka, now running classes at the local University, starts an intern program where he leads a group of newcomers through the department in search of a protégé. Louis is not among these candidates. Masuka picks a man named Peter Latton, who has the highest test scores but, unfortunately, but then faints at a crime scene. Masuka next chooses the attractive runner-up, Ryan Chambers.

Masuka's relationship with Ryan is flirtatious but his prior history with women makes him reluctant to throw too many advances her way. When Batista catches him staring at her, he says, "Hands off."

After awhile, Ryan appears to become rather attracted to Masuka. At the same time, however, we're clued into Ryan's unusual interest in the Ice Truck Killer. Masuka, attempting to win his way in with her, provides a "gift" by showing her the evidence box for the ITK Investigation, which holds Brian Moser's hospital ID and, most importantly, the Prosthetic Arm formerly worn by Monique, one of his victims.

Vince: "It just sits evidence. Forever."

After agreeing to go on a date with Masuka, Ryan secretly snatches the Prosthetic Arm, placing it in her handbag. Soon, Ryan mentions looking at evidence from other cases, such as the Trinity Case and the Bay Harbor Butcher Investigation. Masuka informs her that he can't, since those cases went to the FBI. He promises to make it up to her.

The arm is not discovered to be missing, until Vince Masuka receives a phone call from an unknown caller (who, in reality, is Louis Greene):

Vince: "This is...Vince Masuka!"
Vince: "I can try, what you need?"
Vince: "No, definitely not." (Hangs up the phone)

Less than a minute remains on the bid and he notices the price is at $1,200.00. Attempting to outbid it at $1,300.00, he finds that the auction ended. Masuka has no idea who purchased the hand...and he grills Ryan. She admits that she stole it because she needed money for rent. Vince is furious, stating that the chain of custody is sacred. He fires her, saying that "he's done... with all of it."

Season Six

There is now three confirmed kills by The Doomsday Killer, and Vince Masuka is short an intern. He calls in his third choice to work with him: Louis Greene. During a briefing, Lieutenant Debra Morgan and Detective Mike Anderson run over details of the murder of Erin Baer. Masuka mentions the discovery of a third number - 1244 (the previous two being 1237 and 1242). Suddenly, Louis speaks up, saying he had checked on the numbers usage in the Book of Revelation, only to be interrupted by Debra. Not recognizing him, she asks who he is. Masuka states that his name is Louis Greene, the "latest and greatest intern from his forensics class," adding that Louis is up to speed with the Doomsday Killer Investigation. Louis is allowed to continue, after a question about Ryan Chambers (which Masuka curtly dismisses with, "She's gone!"

Louis informs the team that numerology is covered extensively in Revelation, but the only number that's repeatedly referenced (in the thousands) is 1260. Mike and Sergeant Angel Batista propose that the number is counting up to something, with Louis suggesting the "end of the world, the Rapture..." Debra hopefully asks Dexter if he discovered any evidence on the angel wings. Reluctantly, Dexter lies to her, saying that he found nothing (so that he can investigate the man he saw in the crowd). Debra orders the team to keep searching for Gellar, and dismisses the meeting.

As everyone clears out, Masuka approaches Louis, making note of Louis's abilities with computers. Louis smiles and admits that he tools around, having done some consulting, and even made a couple RPGs (role-playing games). Vince gives his perverted smirk as he asks if any of them feature "Amazon women of immense strength." Louis smiles a bit awkwardly, responding with a "no." Masuka drops the topic and asks to use Louis's laptop. He locates the site, by entering the words "Ice Truck Killer." Louis says it out loud, a bit shocked, and Masuka tells him to keep it down. Masuka states that if word gets out that evidence is disappearing, it would put the whole department in a big mess, including himself.

Louis asks why not just get it back from the seller. Masuka replies that he tried, but he didn't have the selling information that was given to the auction. Louis catches on to what Masuka wants, which is to make the problem go away. He smiles and tells Masuka, "I'll look into it," before sitting down to work on the issue.

A few days later, Masuka asks Louis if there is progress on the... [discreetly moves his hand around stiffly]. Louis regretfully informs him that he was unable to get the hand back because the buyer used an e-sniper program that firewalls the buyer, so whoever has it...has it for good. Vince shows his worry, until Louis continues with, "However..." To Masuka's relief, Louis says that he removed all traces of the sale on the internet, so it's like it never happened. He adds that he improved Masuka's credit rating, installed a modded-up intel chip to over-clock the CPU, and a porn scrubber. A very pleased Masuka expresses his gratitude to his new favorite intern.

Unfortunately, the next time Louis is seen, Brother Sam has been found shot at Good Shepherd Auto Repair. In critical condition, Sam is sent by ambulance to the hospital. Dexter Morgan arrives on scene to figure out who did this to his friend (vowing to himself they will pay for it). Louis stands talking with Masuka about the crime scene when Dexter begins to explain step-by-step exactly what happened. Louis smiles widely and calls him a "fucking rock star" while he stares on with awe at Dexter's abilities. Dexter glances at him and starts looking for additional evidence.

Dexter begins to track a man named Leo Hernandez, a shot-caller who had replaced Dexter's previous victim, and who had threatened Brother Sam. Unfortunately, Detective Mike Anderson tracks Leo quickly enough to make it to his house before Dexter can make a move. A gunfight ensues, with Leo being gunned down by Mike and several police officers. Dexter, feeling that he lost his chance at revenge, arrives on scene with his forensic kit. Louis is there and excited to see Dexter. Louis asks to watch him do the blood-spatter work (almost like a kid in a candy store). Dexter gives him an awkward glance, and Masuka tells Louis that he's not ready for blood work since he's still learning fingerprints. The two head inside and Dexter follows, where he soon discovers a DVD that clues him in that the real killer may have actually been Nick.

Invited along with the entire department, Louis arrives at Debra Morgan's housewarming party. He spots Jamie Batista and eavesdrops on her conversation with Deb about Harrison and Dexter. When Debra walks away, Louis approaches Jamie with an awkward first line:


They continue to talk, with Jamie inquiring if he wishes to become a forensic analyst. Louis answers that he actually already has a career - a creator of video games.Jamie is impressed by this, saying it's "so cool" and she asks why he's working as a lab intern. He says it is inspiration for a new game he's creating about Homicide.

An intoxicated Joey Quinn arrives at the party and begins to flirt with Jamie. Louis tries to get Quinn to back off by stating that he and Jamie were talking. Quinn tells Louis to run back to the lab, while referring to him as "Igor." Batista observes Quinn being obnoxious. When Quinn remarks that Jamie has an "outrageous ass," he punches Quinn in the face. Before Quinn leaves the party, he has a moment with Debra where he reveals his heartbreak over her.

Jonah Mitchell is found the sole survivor of an incident in Nebraska thought to involve the Trinity Killer (who has been dead since 2009). Dexter (with urging from a construct of his deceased brother) takes a trip to Nebraska to find out more about the situation. He tells no one where he is going.

Meanwhile, Debra deals with internal problems, as well as trying to figure out where her brother went. Sergeant Angel Batista mentions that Jamie notified him about her watching Harrison for a few days while Dexter is out of town. Jamie said she didn't know where Dexter went, during their larger conversation about her date with Louis. Hearing that Jamie and Louis are dating both surprises and amuses Debra.


Detective Mike Anderson reads aloud a quote regarding the Whore of Babylon, leading the team to talk over the case of Holly Benson, a recently released captive. Holly thought two men were involved - an older man called The Professor and another younger one who released her. If the accomplice is a former student of Professor James Gellar, the total possibilities (excluding females) are 2400 students. When Louis remarks that the number isn't that big, Masuka jokes unless they're talking virgins. Louis offers to help.

While Harrison is sleeping, Louis and Jamie are sitting on the sofa in Dexter's Apartment, just hanging out. She begs him to show her his new game and promises to keep it a secret. She gives him a kiss to seal the deal. He jokes that the kiss is a contract and then opens up his laptop to reveal the game he's working on. Louis cautions that it's rough, not even a beta version. Jamie watches the game, which is based around the police department. When she see her brother, his likeness amazes her. She asks if he is the main character, and Louis explains that if Angel is the lead on a case, he is "kind of" the star. Suddenly, Debra burst into the apartment and Louis closes his laptop. He listens to Jamie and Debra talk about Dexter's mysterious disappearance.

The next day, Masuka has a surprise for Debra, who is worried over the 2400 names she has to go through to find the accomplice. He tells Louis to go ahead, and Louis explains that he created a program to cross-reference former students of Gellar with people living within a 20-mile radius of Miami (excluding a few variables). The list now only has 200 names. It wasn't legal, but Masuka states that Louis isn't an employee of Miami Metro, just an unpaid intern. As Debra looks through the list, Travis Marshall is seen on the third page.

After working at a crime scene, Dexter returns to the department. As he carries a coffee, Louis calls out his name, excitedly runs up to him, and expresses his admiration for Dexter's discovery that the body had been re-positioned He asks Dexter to teach him how he figures things out so easily. Dexter brushes Louis off with, "Yeah sure. We'll do that...sometime, but right now I've gotta..." and he walks towards the briefing room. Louis follows Dexter in and stands next to him.

Debra goes over the Doomsday Killer case, stating that the city is freaking out, with over 100 calls coming in each day. She thanks Louis for condensing the list of possible accomplices to only about 200 people. She tells the team to divide up the names and keep investigating. The group disperses, and Dexter plans a way to get Travis Marshall to trust him.













Dexter (looks at Louis): "What?"
Louis (smiles): "Heh, see you have these character choices. You can be, uh...Dahmer, Jack the Ripper...the Bay Harbor Butcher."

Dexter (sighs, looking at Louis): "...I think this is offensive...(Louis stares at him a bit shocked) ...Who would choose to be a serial killer?"
Louis (becomes nervous): "Well, uh... well I mean it's like a vicarious thrill."








Louis' last day is coming up and he asks Masuka if he can be hired permanently. Masuka only offers some occasional consulting work. He later assists the team when they are tracking Travis at the time of the eclipse.

Season Seven

Dexter finds Louis in his apartment and realizes he had used his laptop. Louis innocently says that he was just looking up basketball scores. Dexter express his displeasure and orders Louis not use his laptop again. That night, when Louis is at home with Jamie, he starts to bad mouth Dexter, calling him a pompous jerk. Jamie defends Dexter stating that he's her boss and he is a nice guy. Louis is shown cancelling Dexter's credit cards, using the information he gathered earlier from Dexter's computer.

Dexter breaks into Louis's penthouse and finds a paper with his credit card numbers, which solves the mystery of why they were cancelled. He turns his attention to Louis' computer. After searching through a few video logs, he finds one with Louis saying, "I would like to see Dexter lying in his own piss and vomit until it is the highlight of his day, NO ONE FUCKS WITH ME."

Hearing Louis unlock his door, Dexter at first hides, but then decides to take advantage of the opportunity. He pushes Louis against a wall and begins to forcifully question him about why he is messing with him. Louis quivers with fear, and explains it's because Dexter criticized his game, which he spent five years working on. Angrily, Dexter warns him to stay away from him, work, and Jamie, with Louis promising that he will.

That night, Dexter finds Louis in his apartment with Jamie, pretending all is well between them. Dexter realizes that Louis is not scared of him. He later drugs Debra and he slips out of her house. Dexter breaks into Louis' apartment and injects him with M99, intending to kill him. After a few seconds, though, he considers his promise to Debra. Dexter calls her and they meet at a park. He admits that he was tempted to kill, but did not go through with it. After a reassured Debra drives away, Dexter leaves Louis, still unconscious, on a park bench. He thinks to himself, "I still need to get you out of my life, but not by taking yours."

To get rid of Louis, Dexter mails the Prosthetic Arm to the forensics department. Inside there is a letter to Louis, explaining that it was returned due to it being drawn on, with a demand for a refund. Masuka realizes that Louis had the arm all along. He shows his fury toward Louis, saying that he stuck his neck out for him and was stabbed in the back. He fires Louis on the spot, without accepting his denial. Louis slowly walks out, angrily looking at Dexter, who just smirks.

Dexter has also anonymously sent Jamie a video of Louis with a hooker. When Louis arrives home, Jamie shows him the video. He tells her it's not cheating if you pay for it. She lashes out at Louis, stating that she never wants to see him again. He tries to blame it on Dexter, but Jamie doesn't believe him and storms out. Jamie's breakup with him, added to the fact that Dexter set him up to be fired, enrages Louis and he is determined to ruin Dexter's life.

The next day, Louis begins drilling a hole in Dexter's boat, planning to sink it, only for Isaak Sirko with his men to arrive and question him. Louis is placed in a position where his life is on the line and so he tells them all about Dexter and how he wanted to get revenge on him by sinking his boat. Although Isaak tells Louis that he will let him go, Louis is shot in the head and dies on Dexter's boat. Isaak's subordinate, George Novikov, gets rid of the body. Later, Dexter uncovers Louis' murder while cleaning the Slice of Life.
