Since birth, Travis had a psychological disorder that made him extremely violent. He killed his parents at childhood, then killed his Professor feeling that he was "invincible", and shut out the memory entirely. It is believed that he is used the Doomsday Killings simply in order to satisfy his need to kill, a "Justification" that he was searching for.

Travis Marshall, A.K.A The Doomsday Killer or DDK, is a character in DEXTER. He worked at the Miami Museum of Art as a Conservator in Papers and Bindings (for paintings, artifacts, etc.) and studied at the University of Tallahassee, where he earned his Masters Degree in Art History.


Travis is a tall Caucasian with brown hair and green eyes. He is of slim fit, similar to Dexter Morgan and Jordan Chase, however, he is the youngest out of any main antagonist to date. Physically he is very strong, able to lift up women with ease and even manages to pull Nathan Roberts from one area and toss him into a room with little strain.

Travis dresses conservatively, usually wearing button-down shirts and chinos. His style emulates that of his teacher, Professor James Gellar, who is always seen wearing a dress shirt and a cardigan.


Travis suffers from severe psychological effects such as delusions of grandeur, violent tendencies, and a lack of empathy. He is also a master of manipulation. His delusional mindset forces him to imagine that a man he'd killed named Professor James Gellar is still alive, and Travis continues to interact with him although he doesn't actually exist. (This is established in "Ricochet Rabbit.")

Travis captures sacrificial victims, believing that "Professor Gellar" is the one killing them (when, in reality, it's himself). Furthermore,Travis undergoes periods of amnesia, shown after he killed Trent Casey and Lisa Marshall. When Travis is confronted with the dead body of Gellar, he fully accepts the darkness within himself.

The End of Days that Travis is trying to enact is a justification for his need to kill and he's willing to manipulate anyone for his cause, effectively creating two disciples in Steve Dorsey and his wife Beth Dorsey.

Other than Travis, no character in the series has such a severe delusional disorder. Dexter's illusions are simply personifications of his inner dialogue. They do not perform harmful actions except, in one instance, when Brian Moser "took control" in killing a man named Norm. It was immediately shown that Dexter had actually killed him.

The Good Side

Brother Sam: "The good book tells us that there's no darkness that the light can't overcome. So all the darkness that you think you've got inside you, all it takes is just a little bit of light to keep it at bay"

Since Travis has distinct personalities, he is faced with the fact that he follows Professor Gellar but the goodness inside of him prevents his own persona from actually killing anyone. This goodness is seen plainly by his sister, Lisa Marshall, who cares for her little brother fondly and wishes she could see him more often but his work, along with following Professor Gellar, prevents it most of the time. Gellar sees this heart as well, though still encourages him to aide in his dark acts of punishing humanity in God's name.

Travis is calm, collected and a very neat individual. His personality shows that of a soft-speaking gentleman, being seen as polite and rather attractive by various women while his household is kept very orderly and clean. He breaks this quiet nature when confronted however, in trying to convince Nathan Roberts to beg for forgiveness he screams and scolds him and when caught by Dexter Morgan (temporarily and let go), he speaks the open truth about his inability to actually kill people.

The Dark Side

This personality is the one Travis fought to conceal, a personality that kills at leisure until given a purpose - Ending the World. Travis' religious beliefs are set to enacting his dark tendencies into the horrendous crimes he commits. He does not care who he manipulates into his cause, but if they die in the process he views it as a "sacrifice" and shares no remorse for their passing. Even in using the dead body of Professor Gellar against him, Travis is more enraged than sad. His pure focus is on executing God's plan.

This Travis is so far beyond human empathy that he would target an innocent child feeling that it would help bringing the end of the world and as such, he is the first main antagonist to become a serious threat to Harrison Morgan as previews for This is the Way the World Ends show him kidnapping the child and is prepared to sacrifice him.

Good vs. Dark

To the good side of Travis, he sees Professor Gellar as a living being. He views him as a man he respected, honors and follows...though apparently the dark side of Travis also sees this Gellar. It could be the two personalities conflicting but Travis is convinced in finishing what they started.

For the good side of Travis, his relationship with Gellar is an interesting one, while at first glance the two appear to be acting together as a sound set of individuals with a purpose it's revealed that it was Travis all along with the thought that Gellar was still there with him. Travis follows Gellar due to his faith in God and believes his convincing words over the End of Days, feeling that he has to aide his teacher while also looking up to him as a role model of strength and power. At the same time, it can be seen in his expressions that he doesn't agree with everything Gellar does, especially when it comes to the way the victims are treated. Travis often acts as a child would around a stern parent, looking down as he speaks of what his intentions away from the killings are such as going to visit his sister or even going out on a date with a woman. He even begs that Erin Baer not be taken as a victim, but forces himself to agree with the killing regardless. Once he encountered Dexter, Travis started to doubt Gellar more and more but still did not realize he was gone...and the dark side was getting frustrated by Travis' attempt to shut out the darkness.

When Travis tried to have a normal life, his darkness forced Travis to bring a shovel to his own head and render the good half "unconscious" while the dark side of Travis could take care of his sister without interference. Once she was displayed as the whore of Babylon, Travis somehow chained himself within the church and even burned his own arm with a hot poker punishing the good half of himself for betrayal. It would seem that Travis always "awakens" when he's allowed to return to his good personality, thus allowing the image of Professor Gellar to remain a constant reminder from the dark side. It is possible that his darkness wishes to force the good out, ensure that nothing else can prevent its work to be finished.

After Travis finally realizes that Professor Gellar has been dead all along and the memories return, he goes through an emotional state where he casts off need for the Passenger of Gellar that he's held on to for so long, along with any sign of good in his heart. Now focused, a single minded individual...Darkness has won and he intends to enact his tableaus without a second thought.

Theme Music

Travis's Theme 1
Ripped Theme from Season Six
Trouble with the audio sample?
Note: The track is ripped from audio coming from Season Six and as such, contains some sound effects and voice.

Travis has at least two themes, one of them is featured prominently as a tune played on an organ based piano. The track symbolizes the complexity of Travis' personality, showing the darkness while matching with the religious theme of the season. The theme ends with a more dramatic effect.

Travis's Theme 2
Ripped Theme from Season Six
Trouble with the audio sample?

The second theme has slight chorus usage and is a lot more traumatic of a theme, heard in A Horse of a Different Color just before Erin Baer is killed and then Get Gellar, when Dexter discovers that Professor Gellar has been dead all along.

History of Killer

Early Life

Travis Marshall was born 24 November 1977. Travis was the younger of two children, his older sister being Lisa Marshall. At an unspecified time in Travis' childhood, Travis effectively kills both of his parents by taking control of a steering wheel thus forcing the vehicle they were driving to crash into a tree. The incident was recorded as a car accident, however a psyche evaluation revealed that his doctor felt Travis was the one responsible for their deaths. His older sister Lisa never knew this fact about her brother, thus it is assumed she was not in the vehicle at the time (and because he survived where her parents didn't, she became protective of him wanting to shield her brother unknowingly from danger).

Psychological Issues

Travis grew up while also being assigned to a Dr. Benjamin Carlson, who handled his psychological care. According to his reports, Travis often had "breaks from reality" including violent tendencies since childhood, lack of empathy, master manipulator and delusions of grandeur. There were no signs of parental abuse (likely referencing Arthur Mitchell in this sense) nor was there any significant event in his lifetime that would have created this darkness (such as the death of Laura Moser for both Dexter Morgan and Brian Moser), so Travis was "a monster from the start". Travis was given a prescription of Chlorpromazine, which is a form of anti-psychotics however they were not efficient in preventing him from killing.

Travis and Professor Gellar

He would eventually attend the University of Tallahassee where he met Professor James Gellar, a teacher in Religious Studies. Gellar was working on a theory based on an Early A.D. Cult known as the Enesserrette, that had believed they found a Code that would trigger the End of Days. Gellar, with a philosophical interest in the subject, began making private notes on the subject feeling that he had finally deciphered the code. Travis would go on to graduate from the facility, entering becoming employed at the Miami Museum of Art as a Conservator in Papers and Bindings.

In 2008, Travis (likely having already known about Gellar's notes) approached his former Professor, having stolen the Sword of John the Revelator. This event cost Gellar his job but Travis would continue to claim that they were the Two Witnesses from Revelation 11. Gellar would tell Travis that he was delusional and needed help, something that he didn't listen to as he was convinced that he could make Gellar believe that they were the chosen ones. Eventually, to help "prove" his theory, Travis stabbed the Professor with the sword stating that neither of them could ever be harmed. Gellar died from the wound and was locked away in a freezer beneath the church named Santa Maria de Laredo.

Travis shut out this memory and began seeing an illusion that he believed to be the real Professor Gellar though he was merely a representation of his Dark Passenger. He would aide the "Professor" in preparing for the End of Days, which didn't result in a murder until 2011.

Season Six

Travis makes his first appearance, alongside Professor Gellar. The season's storyline is of light and darkness, as well as religion. The persona of Professor Gellar is the darkness in Travis' life while his sister is the light. This is similar to the way that Brian Moser represents the darkness inside Dexter while Harry Morgan is the opposite.

The Seven Snakes


Travis observing a pregnant Snake

Professor Gellar and Travis Marshall are both seen riding a boat wading through a swamp somewhere in Florida. Under a crimson moon, they search for a female snake, pregnant with at least seven snakelets. Travis manages to catch one quite easily, holding it within his hands with no fear. Gellar approves of the catch, likely resulting in them either cutting open the snake or waiting for it to bear the children (as they can be seen physically swimming about within her body).

Scales of Justice

The Scales of Justice is one of the minor tableaus.


Travis meets Omar

On the day following the capture of the snakes, both Travis and Gellar wait outside of a bustling street, where across from them is a fruit stand run by vendor, Omar Rivera. Travis, readying himself to leave and go over to him is stopped by Gellar temporarily, noting a passing car. Then allowing him to move outside, Travis heads to the back of his car and pulls out a bag before heading over to greet Omar. While Omar's back is turned, Travis approaches with the following quotation:

"In the midst of the street was the tree of life, which bares twelve manner of fruit and yielded her fruit every month".


Preparing to kill his victim

Omar turns and asks Travis what he needs, to which Travis replies with a request for oranges. Omar uses the Spanish word for the fruit and turns to get them, while Travis sets down his bag and removes a long blade similar to a machete. He then stands there and takes a deep breathe, preparing himself to attack. Travis assaults the man when his back is turned, dragging his body behind the fruit stand down a hill. He disembowels the victim and replaces the intestines with the baby snakes, then sews up the victim with the symbol for Alpha and Omega.

Season 6 - 3

Dexter discovers the intestines left behind

Dexter Morgan, the forensic blood spatter analyst from Miami Metro Homicide, is called in to a bizarre crime scene where a fruit vendor has gone missing. He arrives on scene to find Vince Masuka as well as his sister Detective Debra Morgan and her partner Joey Quinn, in addition to a stream of students anxious for the Intern level position with the Miami PD. Dexter notices the intestines left within the scale, which later Detective Mike Anderson claims to be a sign of judgement.[1] Dexter follows a blood trail down to behind the fruit vendor and proceeds to detail the event. He claims that the victim was struck from behind, dragged. and then stabbed to death before being disemboweled on the ground at this level. In regards to the intestines left in the scale, there is a hidden message within them that isn't discovered until later on.[2].

Seven Headed Serpent

The Seven Headed Serpent is one of the shorter Tableaus, only spanning mostly in the episode Those Kinds of Things' and continuing partially in A Horse of a Different Color.


The body of Omar Rivera, washed up on shore

The body of Omar Rivera later washes up on shore at a beach where a jogger calls it in, with Dexter Morgan is once again called on scene to investigate. He finds everyone from before here, with the addition of Vince's chosen top pick Peter who is seen taking pictures of the body. Debra and Quinn joke about the choice, thinking that Vince would rather choose the attractive girl Ryan Chambers which Vince replies by saying he chose the person with the highest test scores (but doesn't go without complimenting the "breasts and buttocks" of the hot chick).


Victim's belly with Snakes escaping sewn wound


Dexter marvels at the oddity of this crime scene

Vince brings Dexter over, who investigates the body to find unusual markings on his stomach. Quinn informs them that the symbol is Greek for Alpha and Omega while Dexter removes the man's wallet to confirm an ID for the victim. Then the stomach begins to move, something that Dexter takes an interested fascination with as he cuts open a slight bit of the stitching to release seven baby snakes from within. Dexter's mouth gapes with the look he hasn't had since his brother Brian Moser, the Ice Truck Killer, started killing in Miami over 5 years before. He proceeds to bag the snakes, observing them while the nearby assistant Peter faints and the group informs Masuka he's not a very good choice for an intern. Vince bids goodbye to the passed out intern and to himself, welcomes "little miss hottie." Debra ponders the meaning of the symbol and the snakes, bouncing the idea back and forth that it's some kind of message, a warning even while Dexter thinks to himself the elaborate thought process behind the message and what it could mean.


Travis and Gellar at the dock

Both Gellar and Travis walk out to a dock, looking upon the river as they quote the following:

Gellar: "I stood upon the sands of the sea and I saw a serpent rise up out of the sea, having seven heads."
Travis: "And upon his heads the name of blasphemy."
Travis: "So it's begun?"
Gellar: "Yes, it's begun."

Gellar begins to smile and laugh a little bit before proudly patting Travis on his shoulders. Their first message properly sent, the two men ready themselves for the next more complex ritual: The Four Horseman.

The Mission Continues


Travis' bag rips and reveals a mannequins parts.

Both men are seen carrying trash bags from their car up to the church they've been staying at, talking about how they'll be ready soon. Travis informs Gellar that he may be a little late tomorrow, to which Gellar responds by asking why he wasn't told sooner. He says that he can't help it and that it shouldn't take long, Gellar speaking once more that he has to find another (victim). Travis replies with a louder tone that he already knows that and as he turns, the bag trash bag rips revealing a variety of mannequin parts with a torso rolling down onto the sidewalk below. Gellar says "Now look what you've done..." while Travis apologizes quickly and heads down to pick up the pieces, only to be told it's alright that these things happen. Gellar expresses then that he wants to make sure he can count on Travis and Travis says that he can, something Gellar acknowledges and lets him pick up the rest of the pieces except for a head, which Gellar inspects fondly.

Travis's Sister


Travis arrives at his sister's house

The next night, as Travis said, he arrives at someone's house stealthily walking from the front door to the kitchen. He approaches a woman and gently taps her arm which scares the life out of her for a moment. She says "God Damn It", to which Travis replies that he really wishes she wouldn't say that word and calls him her brother as she hugs him, wishing he'd use the doorbell for a change.


Travis and Lisa at dinner


Lisa Marshall, Travis' older sister, then serves him dinner and the two talk of why he hasn't been around lately. He admits that that the reason he's been gone so much is his work and she sighs, feeling that it's really taxing on him. She talks about her job as an elementary art teacher trying to keep a bunch of fifth graders focused on art. She then mentions that a flock of dead birds were found up north and the following quotation is mentioned:

Lisa: "They think it's the end of the world, or something."
Travis: "What if it were?"


Travis hints at possible reasoning behind his "work".

This gives some insight into the possible motive behind what Gellar and Travis are trying to accomplish, that it really is a warning for the apocalypse. She laughs and brings out a tub of ice cream she wants to share with her brother. He urges her that he needs to go but she insists that he stay, blow off work for once to spend time with her. He then begins to mention that it's before something started but doesn't finish, telling her it's nothing. She laments on how they used to be able to spend time together, talk and how she wants to spend time with her baby brother. Eventually he gives in and agrees to spend time there tonight, effectively not meeting up with Gellar this night.


Gellar observing a fire as Travis explains the previous night

Travis arrives at the church where Gellar is sitting at alter, watching over a fire while heating a rod. He asks where Travis was last night and he replies by telling him he was at his sister's, that she was worried about him. Gellar informs him that she "can't be saved" but Travis goes on to say that she's a good person and all that he has. Gellar turns and says it isn't true, that he has him and God now...but stands up with rod in hand and says that he needs to be reminded of that. The rod, heated and able to burn, prepares Travis to accept punishment for what he did...but instead of using it on Travis, he places it upon his own arm and starts burning it. (Later, a burn mark is seen on Travis's arm.


Travis begging Gellar to stop burning himself

Travis tries to prevent this, grabbing both of his hands and trying to remove the rod from burning Gellar's forearm. He then starts to lower himself and beg for forgiveness, to prove himself worthy. Gellar says that it is his responsibility to watch over Travis, not his sister's or anyone else.

The Four Horsemen

he Four Horsemen spans the duration of the episodes Once Upon A Time..., Smokey and the Bandit and A Horse of a Different Color.

Dexter: "Whoever did this seems to be a member of my tribe...but this is A Horse of a Different Color. What is this?"

The Capture of Nathan Roberts


Travis fakes hurting his ankle to catch his next victim

The same night Travis targets his next victim, setting himself up along the jogging path of the man he's after. He is seen sitting on the ground, grasping his ankle in pain and when the man (Nathan Roberts) arrives asking what's wrong he claims that he sprained his ankle.


Travis standing over his newest victim

When Nathan approaches to try and assist, Travis grabs a nearby rock and smashes it over his head...bringing him back to the church. Gellar approaches and observes the deed, smiling once more towards Travis as he has proven himself and Travis smiles back.


Travis greets his captive

During the daytime, Nathan the newly made captive is struggling to break free from the shackle holding him to the ground. He's inside a dusty room, with an old wooden door behind him with a loop used for a handle. The door opens and in comes Travis, listening to him beg to be set free but he tells him that he must first beg for forgiveness. Nathan then apologizes to Travis, who disregards that notion and says that he must apologize to God, not him.


"You're not going anywhere until you've repented for your sins"

Travis kneels down, calmly saying that he needs to beg for this forgiveness and be sincere, otherwise this will get a lot worse for him. He stands up and leaves Nathan to remain shackled, spending his time working on the shackle.


"You need to BELIEVE what you are saying, Nathan!"

A little while later Travis returns, holding what appears to be a whip as he proclaims that Nathan must believe in what he's saying if he wants to get out of this, he has to believe in God and truly seek his forgiveness. As Travis stands on, he listens to Nathan cry out his regrets for everything he's ever done and begins to sympathize, placing his hand on his shoulder before choosing to leave. After the door closes, Nathan begins tugging on the chain once more. Out in the chapel area, Professor Gellar tells him that Nathan is only saying that in hopes of being let go, to make him hear what he wants to hear.


Travis approaches him, asking how much longer he must be made to suffer. Gellar remarks on his good heart, saying that's why he chose him but stands up to say that regardless, there is so much more at stake than one man's suffering. They must be strong while he must be pure otherwise they can't proceed, however he attempts to lift Travis' spirits by telling him that he's coming around and that it just takes time.


"You have to make a choice, Nathan. Do you want to be saved?"

The time that Nathan has spent trying to pull the shackle loose finally pays off when he breaks free, though still restricted by his hands being tied together. Nathan first tries the door that Travis has been using, only to find that opening it may make too much noise so he chooses an alternate path which wraps around through the main chapel area. After pushing aside a pew, he nears the entrance when he spots a horse and as it rears up upon noticing him, he falls back frightened. Shortly thereafter Travis takes him by the arm and head, showing remarkable strength as he pulls the man and throws him to the floor back in the room from before. He asks if he wants to be saved, that he has to make a choice and Nathan grovels at his feet once more begging for his life, saying that he wishes to be cleansed of his sins. Travis stands there with an expression of a man who thinks he's ready and then Professor Gellar confirms it, telling him that it's time.

The Four Horsemen Tableau


The Four Horseman Commeth

It's a bright sunny day during a festival of some kind, where many people are gathered on the street. Cars drive by, the sun gleams, but a thumping noise is heard in the distance.


Nathan's head on a mannequin as part of the four horseman of the apocalypse

In the distance, traveling down the road are four horses, each with an apparent rider. The civilians look to these horses, confused as if this is some sort of parade but are suddenly greeted by the grotesque sight of body parts sewn together with the mannequin frames. Four riders, one man...Nathan Roberts has been "freed" and sends a message to all about the end of days.


Dexter Morgan, who bore interest in the "snakes victim" when he visited the crime scene beforehand, now walks onto a scene like he's never seen before. Even he, a man who is on the fence over belief in a higher power remarks "Jesus Christ!" when he witnesses a horse walking around with body parts attached to it (namely, the head of Nathan Roberts at first). He walks through the crime scene, looking at the spectacle as he meets with his sister Lieutenant Debra Morgan, filling her first time on scene in her new position.


In Awe over the scene, the imagination of the crime reminds him of his brother Brian.

He is reminded of his brother Brian Moser while remarking on the "wicked rodeo", caught off guard by Deb thinking the same thing. Except when he envisions the imagination behind these killings, she states the brutality of it.

Debra: "Same sick fuck, two different killings."

An Alpha and Omega Link


She leads him to one of the horses, detailing the symbol for "Alpha and Omega", which relates the previous Snakes Victim to this new murder. Forgetting her position as Lieutenant, she snaps at Joey Quinn who was simply providing his report along with Sergeant Angel Batista and Vince Masuka. Batista confirms to the two of them that a local stable about a mile from their location reported four horses missing, Quinn says that patrol will be on their way within the hour and Masuka reports that all body parts are the same blood type (B+), feeling that they are all from a single victim. Dexter wonders what killer is trying to tell them, when Detective Mike Anderson approaches with an answer.


Mike offers insight into the crime

Mike: "He's saying it's the end of the world, something like that. Four horseman of the apocalypse; white, red, pale and black. Doesn't take a genius to figure it out. The killer is showing us a scene from the Book of Revelation"

The others aren't instantly taken by Mike but Debra introduces him nonetheless, learning from Mike that this is a scene from the Book of Revelation, relating religious motive in addition to the symbol for Alpha and Omega. She inquires about the snakes but Mike says he isn't sure about it, that he'll have to research more data to figure out the situation. She then tells Masuka and Batista to head to the stables for info while Dexter and Vince take care of the body. Dexter relates the killing to that of his "tribe", being as the killer chopped up the body parts much like himself and his brother but doesn't understand exactly what this is.

Mysterious Numbers


Dexter works with the body, trying to figure out clues


If James Doakes were still alive (and didn't know the truth about Dexter), he'd certainly comment on the way Dexter handles his observation of the corpse here. His movements and expression suggest a keen interest and almost thrill from this experience, moving body part to body part together to form a completed puzzle and even picks up the decapitated head placing it to finish the structure while Deb gives somewhat of a nauseated look. Dexter Morgan confirms that the kill wound (located on the chest) was the same as that for Omar Rivera (the Snakes Victim), then states the same insignia being used for both crimes. Debra proceeds to ask about the cuts on the body, what could have caused it with Dexter suggesting a bone saw.

1237 and 1242

Something catches his attention, a small object stuck under the left eyelid of the victim. Using a pair of tweezers, he obtains a small note and opens it up revealing the numbers "1242". Puzzled by it, he grins to Debra as he ponders on whether the other victim also has a similar message on his body. He looks over the corpse but finds nothing anywhere on him, even though Debra suggests other locations on the corpse such as the mouth. She asks what they could be missing and once again he smirks, remembering what's not in him: the intestines. Having them wheeled in on a cart, Dexter open one of the intestines while comparing this to looking through a cereal box for the prize. He manages to locate another message, which reads "1237." Dexter and Debra question what the numbers mean in the following comments:

Dexter: "1237 and 1242, what do you think it means?"
Debra: "That I've only been Lieutenant for a week and there's already some game-playing sick as fuck serial killer for me to catch?"
Dexter: "Technically he's not a serial killer...yet. Serial killing involves the murder of several people in three or more separate events. So far our guy's only done two."
Debra: "Are you trying to make me feel better...or worse?"


Dexter works on a possible crack in the encoded messaging

In the Investigation Room, Dexter works over the code with his own mathematical interpretation on a notepad. He works over the fact that when Brian sent him a message, they were encoded specifically for him but puts faith in himself that he should be able to crack this code as well. Debra then reintroduces Mike Anderson just for the few who haven't met him yet and he begins to do a run through on the boards of what he's compiled information wise.


He begins to explain his theory that the killer is reenacting scenes from the Book of Revelation, sayings that there is a lot of brutal imagery to choose from. He's cut off by a sudden interruption by the always timely Vince Masuka, who states that traces of oxidized iron (rust) in the victim's corpse and based on the fact that iron hasn't been used in weapons for centuries, Dexter then expresses his curiosity in what kind of weapon could have been used and Masuka says that it was likely an ancient sword of some type. Deb tells Masuka to work on that then lets Mike continue. Mike says that the killer has given them three tableaus (theatrical term for a picturesque group of people or objects) in the intestines on the scale, the snakes victim and the four horseman. The Four Horseman of the Apocalypse are described in Revelation 6, verse 1 through 8 while the Snakes are mentioned in Revelation 13: "And I stood upon the sand of the sea and saw a serpent rise out of the sea having seven heads". He makes an interesting hypothesis of the intestines meaning, suggesting that they are a symbol for God's judgement on the human race (as the intestines were left on the scale at the fruit stand).

The Doomsday Killer Gets his Name

Dexter then begins to realize based on the numbers of 1237 and 1242, that they in fact have a difference of 5 and the murders took place five days apart. Batista then suggests that if they're counting up to something, then it must be the end of the world. It's then that she tells Batista and Quinn to round up any ends time fanatics while also finally dubbing the murderer: The Doomsday Killer.

The Investigation


Dexter researching the Revelations of John

Dexter Morgan, while at his apartment, begins investigating a series of printouts regarding the Book of Revelation by John the Revelator. He notes the swarms of locusts, bowls of wrath and in feeling that religion was meant to be comforting why anyone would believe in these darker portions of faith. He's interrupted in his research by his sister, Debra Morgan who is preparing herself for the press conference regarding the Doomsday Killer and the Four Horseman Case from earlier. She frustrates herself with catching Doomsday while dealing with her duties as Lieutenant, Dexter encourages her that she'll find a way to do it she always does.

Brother Sam's Viewpoint


"Lord have Mercy..Sins in the Name of God, the Devil is busy"

Regarding a second car accident that occurred in Dexter hunting down Walter Kenney, he returns to get a second estimate on new repairs for his vehicle from Brother Sam. While working over the numbers, Dexter picks up Sam's bible and flips through it to find some notes highlighted by Sam who says that every time he reads it, he finds something new. Dexter says that he's started reading the bible for work, regarding their tracking of a killer in Miami whom they believe to be reenacting scenes from the Book of Revelation. Sam sighs, having heard of the Four Horseman Case and says that just because a man "believes in some crazy bullshit" and does things in the name of God...doesn't make his faith any less real.

Brother Sam: "Faith man, you put it in the wrong things...fuck you up"


Back at the station, Dexter Morgan looks over Angel Batista and Joey Quinn's "people of interest" regarding this case. Most of them are fanatic "end times" believers and show this belief by arguing among themselves. Meanwhile Lieutenant Debra Morgan and Captain Maria LaGuerta discuss how she can prepare for the press statement on the Four Horseman Case when she's given the suggestion of just being herself on camera. She takes it as a bit of a surprise but acknowledges it for the statement to come.


Dexter and Harry ponder over the way the body was dismembered

Dexter remembers that Brother Sam reads the bible multiple times and finds something new. He becomes curious over the cuts made to Nathan's corpse, goes over another look at the corpse while Harry Morgan watches on. Harry makes the observation over how aggressive and brutal the cuts are, something that doesn't make sense to Dexter who admires how precise and planned the crime scenes were left. The thought runs through Harry's mind asking why such a careful man would be so reckless in dismembering the corpse and Dexter realizes that it might not just be one killer, in fact there is the possibility of two.

Deb's Press Conference


"All I care about is catching the fucker that did this"

The press conference finally happens, news about this case has to be released in some format and Lieutenant Debra Morgan is the one that has to inform the public. Starting out somewhat formal and regular, she begins to drop the standard approach and begins to ask the public for their assistance, reporting that she doesn't care about press conferences or politics, only catching the man who did this. Now with the public's knowledge that the Snakes Victim and Four Horseman Case are related, more of Professor Gellar's plan will come to light.

Gellar's Website


"Dude, quit staring at're freaking me out!"

After the conference, Sergeant Angel Batista and Detective Joey Quinn head off to find Jeremiah Allen, one of the "nut jobs" they have to interview. Unfortunately they get a false address and end up waiting in the car, discovering that Angel's going through a mid life crisis and in addition the two men spot a blunt hidden in the new car he's picked up. The two decide to get high and have a comical moment when they finally receive the call to locate Jeremiah Allen.

Debra Morgan is praised for her work by Deputy Chief Tom Matthews for her performance in the press conference. Something she didn't expect but she accepts nonetheless, while later on she is informed by Sergeant Angel Batista and Detective Joey Quinn about a new lead they've discovered from the man they interviewed, Jeremiah Allen.

Gellar's website

Allen is obsessed with a revelation expert known as James Gellar, a name that Detective Mike Anderson is familiar with as a Professor from the University of Tallahassee. He brings up a website that he had previously researched (, not a real site show purpose only) which depicts the end of days by Gellar's point of view. Angel tells them that they can't find Gellar because he went "underground", three years ago he was accused of stealing an Ancient Sword that originally belonged to John the Revelator, the man responsible for writing Revelations. Debra figures the sword was likely the one Vince Masuka suggested could have been used in the murders.

The Angel of Death

The Angel of Death is one of the shorter Doomsday Tableaus, spanning the duration of the episodes A Horse of a Different Color and then the aptly named The Angel of Death.

During the middle ages it was believed that the outcome of nearly all Earthly events was decided by angels...either Light or Dark. I'm quite certain that face I saw in the crowd was of the Dark variety... - Dexter Morgan, regarding Travis Marshall.


"It's happening Travis, look around us...people are afraid".

Professor Gellar and Travis Marshall are spending their time eating (at least Travis is) at a restaurant discussing the recent Four Horseman incident in the street. He sits back calmly, referencing the fear in everyone's minds and body language from hearing about that incident. He begins to explain that soon everyone will understand what they're trying to accomplish but Travis' focus is on the pretty young waitress named Erin Baer behind Gellar. He asks him if he's paying attention, which Travis notes that people are afraid and Gellar sighs, saying that yes the girl is pretty but they really have to stay focused. Travis looks at him for a moment and asks if he should ask her out, with Gellar replying if that's what he wants. Erin comes over to their table as she greets him by name and pours him some more tea, smiling the whole time before walking away. She doesn't seem to note Gellar's existence at this point.

"We were given free will for a reason, Travis.."

Professor Gellar is seen that night painting a portrait of the Angel of Death, when Travis Marshall comes up behind him to tell him of his plans for the evening. Gellar suspects he is going out on a date with Erin Baer, the waitress from earlier, and Travis says he can cancel if Gellar desires. He tells him he can do what he wishes, that they were given free will for a reason as long as he's willing to accept the consequences. Travis says he'll be back later that night and leaves, while Gellar turns to watch him.

Travis Has a Date


One hell of a first date...


Gellar watches on with disapproval

The date ends up going fairly well for Travis (in the midst he reveals that both of his parents died in an accident) and later that night he takes Erin Baer with him to his house where the two make a leap in romantic interests by sleeping together. For some reason, Gellar is actually in his house and watches on through the crack in the door, a look of disappointment in his eyes as he sees what Travis decided on.

The Capture of Erin


"She's apart of God's plan now"

The following morning Travis awakens and moves through his house until he spots Erin tied up on the floor. He moves to her, telling Gellar that he doesn't want this but Gellar scolds him in the fact that he "shouldn't have defiled her" and now she must be apart of God's plan now. Travis, angry at the decision, looks down and leaves the area while Gellar observes his next victim.


Angel and Quinn tell of their lead, Professor Gellar

Crime Scene

"Catch of the day!" - Vince Masuka


Erin Bear strung up but alive

Another sunny day in Miami, except this time while Dexter Morgan watches over his son Harrison after a surgery, a call comes in from his sister Debra to check out a crime scene in Coral Gables, FL at the Botanical Gardens where an Alpha and Omega Symbol was found outside the property. Dexter drives to Gables and arrives on scene, observing the next Alpha and Omega symbol this time made out of Dead Fish. A droplet of blood on some nearby shrubbery catches Dexter's attention and he moves with the others into the Green House. Debra manages to spot someone strung up and opens the door while Angel Batista, Dexter and a few officers enter the area.


Erin, trying to warn the police it's a trap


Unfortunately, it's sprung and she becomes the third victim

Erin Baer tries her best to warn the others not to get too close and Debra Morgan catches on, standing still as she manages to spot the trip wire. Unfortunately, one of the fellow officers does not and as Debra calls out telling her not to move any further she trips the wire and the trap mechanism on Erin Baer's support harness releases. In an event that takes place in only five seconds, her body falls down while the collar around her neck punctures her jugular, her arms strung up to either side attached to angel wings while blood trickles down her neck. Unfortunately for her...she has become the Angel of Death.


Dexter looks on and finally declares this kill number 3, he's a serial killer now

Although it's not entirely over with her death, a strange sound can be heard from within the green house, something Dexter begins to notice as he informs everyone to quiet down. Angel Batista inquires over the source while Dexter leads them to a nearby cupboard, which Angel prepares to open while having his gun ready. He looks to Dexter to see if he's ready, then opens it.

The Locusts


Locusts burst from the cupboard



Suddenly a swarm of at least a thousand locust free themselves from the cupboard, covering the entire green house while spreading out evenly. One of them lands on Dexter's arm and he picks it up, looking in awe at this sight before making his own exit. Angel and Debra stay behind, as well as the two officers.


Dexter spots Travis for the first time


Travis watches on with true belief

He walks out calmly while the locusts follow him and force everyone outside to cower down to get out of there way. Dexter while looking around manages to spot someone, a man standing there among all those that would hide. Standing in the back, but looking up with a sense of true belief is Travis Marshall. He doesn't see Dexter and rather marvels at the sight before him, smiling as the locusts fly around and up into the air. Dexter can see it though in this man, something he saw before in Brother Sam someone who truly believes. Dexter dubs this man Doomsday Number 2. Little does he realize that there is only one Doomsday Killer.


Dexter struggling with the Angel Wings.

The Angel Wings

Dexter returns to the forensics labs to investigate any information he can obtain from the wings used on Erin Baer. While he feels certain that the face he saw in the crowd (that of Travis') was likely connected to the murders, this newcomer chose to remain anonymous by leaving no trace evidence that could help Dexter or the department pinpoint his location or identity. An idea occurs to him to cut through the layer of wings and examine it for clues, noticing a small repair that was almost skin-like. He cuts a square off with his scalpel and observes it, believing this piece may help him identify the man in the crowd.


Dexter discovers what the ingredient is.

Dexter Morgan continues his investigation into the type of material he cut from the Angel Wing, returning an exact match to what he believed it to be: A polyvinyl acetate polymer dissolved in toluene (in other words, a type of unique glue). By analyzing the data, he's able to find that the backing is calfskin, together revealed to be used in ancient manuscript restoration which is a sure clue in identifying the face (Travis) he saw in the crowd at The Angel of Death crime scene. Vince Masuka arrives to tell Dexter to get to the Investigation Room immediately, his sister demanded their audience. He tells him he'll be there in a minute and as he gives a final look at the screen, he states "this is no amateur".

Tracking Gellar


Gellar is the prime suspect as DDK, for now.


Mike details info he found out about the murder.

Dexter arrives, hearing his sister say that she's glad he could finally join them. and she does a run-down on DDK's most recent victim, Erin Baer. She was a 29 year old waitress who worked at the Glass House Cage at the Miami Cultural Center. Dexter notes the location in his mind, thinking that may be just the place his "mystery person" may be working at or at least it could provide him some clues as to his whereabouts. Deb then states that she has "Unis" (uniformed officers) plastering pictures of Professor Gellar everywhere they can to get the word out on him, see if anyone's seen him. Detective Mike Anderson says he'll take lead on that and then when Deb asks where they are on the Revelations side of this investigation, Mike brings forth his findings. He says that "between the trumpet flowers placed around her, the locusts,and the iconography of an angel", that the Doomsday Killer was most likely referencing Revelation - Chapters 8 through 10. Deb asks him if he has any idea why their entrance trigger Erin's death, that typically a Serial killer wishes to do the kills themselves feeling that's the whole point. He proceeds to grab a bible and explain the following passage:


More insight into the meaning behind the crime scene.

Mike: "There is a passage which reads: 'You must go back and report your message to many peoples, and nations and languages and kings.'"
Deb: "So I'm guessing we're those people" *Mike nods*
Dexter: *Inner dialogue* "It seems his message is more important than the thrill..."



Third number, "1244" along with the other two, "1237" and "1242"

Deb proceeds to ask if they found anything from the ME's Office (Medical Examiner) and Sergeant Angel Batista says that they reported traces of spermicide (a type of chemical used to prevent reproduction during sexual activity, usually distributed within spermicidal condoms) and Detective Joey Quinn states that the ME believes the victim slept with someone who uses spermicidal condoms. Deb wonders if she had sex before she was kidnapped, Quinn thinks maybe it was Gellar but Dexter personally believes that it was Gellar's accomplice (Travis Marshall). They continue to say they'll try and contact Gellar's last contact, Clarissa Porter and follow up on that lead...while Deb asks the "lab boys" what they have. Vince Masuka says that the fish and locusts were all local but he does say that they were able to find a third number on Erin Baer (lodged in her esophagus) and shows it to Deb along with the other numbers, this one being "1244". Deb runs through the numbers in her mind when a new character speaks up...


Louis Greene. The latest and greatest intern from my forensics class.

This is the first time Louis Greene is shown, where he says that he has done some checking on the numbers' usage in the Book of Revelation only to be interrupted by Debra. She asks who he is and Vince states that his name is Louis Greene, the "latest and greatest intern from his forensics class". He informs the team that Louis is up to date with the Doomsday Killer Investigation, allowing him to continue despite the question about where Ryan Chambers went (quickly dismissing it by saying she's gone, wanting to excuse the reason to protect himself and avoid humiliation).

The Count Up to 1260

Louis begins to describe that numerology is covered extensively in Revelation, however the only number that's repeatedly referenced (in the thousands) is 1260. Mike and Sergeant Angel Batista bounce the idea around wondering what exactly this is counting up to, while Louis suggests the "end of the world, the Rapture..." as suggestions. Debra asks Dexter Morgan if he has anything on the wings, who reluctantly lies that he hasn't found anything (which is a cover so he can investigate the the man in the crowd) that forces Deb to have her guys search for some more info, dismissing the meeting.

Whore of Babylon

The Whore of Babylon is roughly the longest Tableau to complete in Season Six, spanning the duration of the following episodes: The Angel of Death, Just Let Go, Nebraska and Sins of Omission.

There's something about Gellar...


"It's a good thing I'm around because we have to find...the Whore of Babylon".

Back at Santa Maria de Laredo, Travis and Gellar are seen on their knees at the alter praying before the statue of Christ on a cross. Travis looks over to his professor to notice an odd sight: blood trickling down from his forehead which forces Travis to look away for a moment then back to see the blood has vanished. Gellar realizes that Travis isn't paying attention to the statue of Christ and tells him to keep his "Eyes on God". After they say amen, Gellar asks Travis to help him up, which he does, and is informed that it's time for them to go hunting. Travis says that he thought that they had more time, but Gellar asks if he still can't hear God talking to him. Travis admits that he's been fasting and praying for days only that God remains silent to him while his own voice bounces around in his head. Gellar walks up to him and says that it's a good thing he's around, because their task is to find The Whore of Babylon.

Travis Meets Dexter


Dexter visits the Cultural Center in search of answers


And he finds them, Travis works at this Museum.

Dexter Morgan makes the trip out to the Miami Cultural Center in search of the man he saw previously. He creates a lie when he approaches the Docent here, saying that he "accidentally poked a hole" in a portrait that belongs to his boss. Before he can finish, the Docent leads him to a room with a projector playing a movie on art restoration. Dexter feels this won't help him but the Docent insists that he watch the video regardless, so Dexter sits down (feeling as if he's getting nowhere) when he notices the familiar face right there in the movie. He figures out that he works in the Museum, but gets a call from Detective Mike Anderson to visit the Beach House to go over a crime scene. Dexter asks the Docent the name of the man in the film, but she tells him to be silent and pay attention to the film, which forces him to walk out feeling that she's the "worst Docent ever."

Later on, Travis is seen getting inside in his vehicle and suddenly Dexter wraps his garrote wire around him, holding Travis in an asphyxiation state. When confronted by Dexter, Travis 'admits' that he could not kill the victims and that Gellar was the one who killed all of them. After hearing this, Dexter lets him go, hoping that Travis will soon lead him to Gellar (the one who really deserves his table). However, Dexter soon finds out that Gellar had been murdered by Travis years ago (having his corpse stuffed in a freezer), and that Travis' master was only hallucinated.  

The Lake of Fire

After everything Travis put him through, Dexter prepares a kill room in a building not far from the ocean, and awaits Travis, who arrives moments later near the docks. They end up struggling and Travis knocks Dexter over and injects him with his own tranquilizer. Travis then ties an unconscious Dexter to a life raft adrift in the ocean, with explosives and gasoline surrounding it. When Dexter awakens, he struggles and Travis comments that he was stupid to think that he could foil "God's" own plan. He then lights a match and throws into the ocean, causing the boat to explode as Travis looks on from The Slice of Life. Dexter is able to escape into the water during the last second, while Travis is confident that "The Beast" has died. However, this is proven wrong when Dexter returns and halts Travis' plan to sacrifice Harrison as 'The Lamb of God'.  

The Lamb

Travis is appalled that Dexter survived, though he still threatens to kill Harrison, should Dexter not obey his commands. Travis asks if Dexter has any M99 with him. Dexter shows him that he does and Travis commands him to inject himself. Dexter either falsely does so or injects himself with a minuscule dose so that, when Travis is about kill Dexter, he uses his reflexes to dodge the sword, before knocking Travis unconscious and then rescuing Harrison. 

Death of Travis

"GOD has nothing to do with this. You are wrapped in plastic because I want to kill you."

While strapped to an altar inside of the church, Dexter converses with Travis one last time, as he does with all of his victims and raises his blade to strike it into

Travis' chest. As he does this, however, Dexter's sister Debra Morgan observes the killing and Dexter is confronted with a problem that he's never faced before - exposure of his Dark Passenger to one of the people he cares for most.

Travis lay dead on the table as Debra stares at Dexter, questioning him about what she just saw. After a heated escalation between the two involving Debra pointing her gun at Dexter and him slowly trying to calm her, a story is fabricated by Travis' killer on to what actually occurred. According to Dexter, Travis was hiding in the church with his sword and tried to kill Dexter when he went for one last forensic sweep. Dexter claimed he some

how snapped, resulting in the strange way Travis was found and murdered, before coming back to his senses. Debra initially believes this and attempts to call in the station to arrive immediately. Dexter stops her, for his own sake...and ultimately convinces her the best way to protect him in this situation would be to dispose of the evidence.


Dexter fills the church with gasoline and lights Travis' corpse ablaze, with the Sword of John the Revelator thrust into his sternum.

Lost Bloodslide

The next day, Miami Metro Homicide arrives to investigate the crime scene with Dexter returning once more. The blood slide Dexter had of Travis fell off the table into a vent, where it was found by LaGuerta, which resulted in her suspicion that the Bay Harbor Butcher was still alive. This would make her pursue the case continuously until she could clear her old friend James Doakes' name for good.

Doomsday Tableaus

Please refer to the Main Article for more info.

The Doomsday Tableaus or Seven Tableaus refer to the seven acts of which will happen before the return of Christ in the Book of Revelation. Travis Marshall reenacts these scenes in order to cause the return of Christ believing he would be saving mankind, however each of these Tableaus takes the form of a Crime Scene in which one or more victims are intended to die.

Major Tableaus

  1. The Seven Headed Serpent
  2. The Four Horsemen
  3. The Angel of Death
  4. The Whore of Babylon
  5. The Bowls of Wrath
  6. The Wormwood
  7. The Lake of Fire

Minor Tableaus

  1. The Scales of Justice
  2. The Lamb (Dexter's son, Harrison Morgan, is intended to be Travis' final kill.)

Modus Operandi

The first kill (Omar Rivera) was done by first capturing a pregnant female snake in a swamp, requiring 7 baby snakes. He then approached Omar and assaulted him with an ancient roman sword over the head, dragged his body down a nearby path and attacked him once more to kill Omar. He then surgically cut open his victim's body, removed all of his intestines and replaced them with baby snakes. He then sewed up the wound and dumped the body in the ocean, expecting it to wash up on shore within the next day or so to send a message. The message, hidden beneath the sewn stitches of the symbol for "Alpha and Omega", involved the snakes...but to whom it is targeted for is unclear. The Second kill was a bit more elaborate, first capturing Nathan Roberts and convincing him to beg for forgiveness from God. In preparation, four horses were stolen from stables in Miami and mannequin parts were brought from somewhere. After Nathan was stabbed in the same location where Omar was killed, his body was cut up into multiple parts (similar to the Bay Harbor Butcher and the Ice Truck Killer), sewn piece by piece to mannequin parts that were then placed on four horses to march into town. The symbol for Alpha and Omega was on the horses heads, painted.

The third victim was a girl named Erin Baer, who developed a relationship with Travis but was seen as unsatisfactory by Professor Gellar, who decided to make her the next kill. She was placed in a green house, set up hanging on a structure with a trip wire that would activate her death. Once the wire was tripped, her arms were pulled up and her body fell while a spiked collar dug into her neck, killing her instantly. In addition, a nearby cupboard was filled with locusts as a sign of the apocalypse. The symbol for Alpha and Omega was found outside formed by dead fish. A fourth victim was intended as the whore of Babylon. Travis' duty in this situation was to brand the mark of Alpha and Omega on the victim while also providing his (and apparently Gellar's) blood for her to drink. Travis, having second thoughts on the event, releases the victim however and she is spared, but Gellar is after a new "whore of babylon", who that will end up being is up to question. Travis uses an Ancient Roman Sword of John the Revelator, surgical equipment to cut open a human corpse and sew it back up.

First body was been dumped in the ocean so it would appear on the beach within a day or so, intended to be found. Second body cut into multiple pieces, sewn to mannequins and ridden into town by four horses; intended to be found. The third body was left in a trap, alive when approached by the police before the trap was set and she was killed, hanging there with blood trickling from the wounds.


Attempted Victims

  • Unnamed woman (attempted to abduct, but failed)
  • Dexter Morgan (attempted to sacrifice twice)
  • Harrison Morgan (attempted to sacrifice once)
  • The entire Miami Metro Homicide Division (attempted to kill with Wormwood).
  • Sergeant Angel Batista (attempted to sacrifice him. Travis knocked him out and tied him to a bed,  threatening to shoot him with a pistol. However, when Travis was alerted of the cops' arrival, he set the room on fire, although Batista was saved by Quinn at the last second).
