Dexter Morgan is the protagonist of both the DEXTER television series and the Dexter Book Series. He is introduced as a serial killer and a blood spatter analyst for the Miami Metro Police Department. As Dexter is the title character, he is featured in every episode as the main focus.

The sixth season of Dexter premiered on October 2, 2011. It follows Dexter's and Miami Metro's investigations into a string of bizarre ritualistic killings featuring religious apocalyptic symbolism.

Season 6: Summary

By the start of Season Six, over a year has passed since Lumen departed and Dexter continues to kill murderers. Two ambulance drivers are ambushed and killed by Dexter. Dexter then goes to his 20th High School Reunion (despite the conflicts with his age[1]) to hunt down old classmate Joe Walker, whom he believes had a hand in Janet Walker's (his own wife) death. After that kill, Dexter begins to stalk an elderly serial killer, The Tooth Fairy Killer, who was active in the 1980s.

Dexter has the assistance of a new nanny named Jamie Batista (the kid sister to Angel Batista, one of Dexter's closest colleagues at work) to watch over his son Harrison while Dexter goes out. Harrison is now old enough that he needs school and Dexter, in trying to find the right thing to pass on to his son, reluctantly chooses religion as something that might give structure to and normalize his life. However, Dexter's atheism conflicts with Harrison's religious preschool.

As he contemplates the value of religion, he finds some understanding through Brother Sam, an ex-con and murderer. Brother Sam is now a born-again Christian who counsels other ex-cons. Dexter initially sees Brother Sam's religious conversion as a scam, but Brother Sam proves himself a changed man. He even helps Dexter through a crisis when Harrison undergoes an appendectomy. Things go awry when Brother Sam is shot dead in his garage. Dexter realizes that a friend of Sam, Nick, is responsible for the shooting and swears revenge. Sam forgives Nick on his deathbed and implores Dexter to also forgive him. When Nick initially appears remorseful, Dexter considers this path of forgiveness over retribution. But Nick's remorse proves to be an act. When Nick begins to laugh and brag about what he did, it enrages Dexter and he drowns Nick in the surf.

After Dexter breaks his promise to Sam and kills Nick, Dexter's darkness appears as an illusion of Brian. He convinces Dexter to go after Arthur Mitchell's son, Jonah, who appears to have become a killer. Dexter tracks Jonah to Nebraska with the intent of killing him, but relents when Jonah explains what happened. When Jonah's sister (due to abuse from their mother) committed suicide in a bathtub, he became so enraged at his mother that he killed her. Jonah, guilt-ridden, then begs Dexter to kill him. After learning this new information, Dexter rejects Brian's influence and reaffirms himself to the "Code of Harry." Dexter returns to Miami, leaving Jonah alive to "forgive" himself.

Vince Masuka's new intern, Louis Greene, has a strong fascination with Dexter as well as the Bay Harbor Butcher and the Ice Truck Killer.

Back in Miami, Dexter continues investigating "The Doomsday Killer," a serial killer who models his crimes after the Book of Revelation. At first, he thinks that the murders are being committed by two people - a fanatically religious college professor named Professor James Gellar and his protegé, Travis Marshall. Dexter tracks Marshall down, but balks at killing him, believing that Marshall has a conscience and is simply being led down the wrong path.

But when Dexter follows Travis to an old church and discovers Gellar's body in a freezer, he concludes that Travis has always acted alone. Travis is forced to accept Gellar's death and no longer visualizes Gellar. Travis begins to think that Dexter is the "False Prophet." He then captures Dexter and enacts The Lake of Fire, although Dexter manages to escape. After swimming for hours, he is rescued by a fishing boat carrying immigrants bound for Florida. While on the boat, he kills Alberto because he is threatening the others with a gun.

Travis kidnaps Harrison to sacrifice as the "Lamb of God" during the eclipse, but Dexter manages to rescue Harrison, knock Travis unconscious, and take him to the old church. Debra walks into the church to tell Dexter how she feels about him, only to see Dexter plunge the knife into Travis' chest. The two look at each other in horror and Dexter exclaims, "Oh God."


  • Ben and Roger - Ben and Roger were two paramedics who purposely let their patients die so they could harvest their organs. Both men are killed simultaneously, having their hearts stopped with a defibrillator.
  • Joe Walker - Joe Walker was a man who went to high school with Dexter, at Alan B. Shepard High. After school, Joe went on to marry Janet Walker, who was also one of the only people that spoke to Dexter in high school. Prior to the events of Season Six, Janet was found dead, due to an apparent suicide. However, blood was found under her fingernails, which caused Dexter to believe that there was more to her death. After matching a sample of Joe's blood with the samples found under her fingernails, Dexter has all the proof he needs to kill Joe Walker. Joe is killed after being hit in the face with a sledge hammer and stabbed in the chest.
  • Julio Benes - Julio Benes was the leader of the street gang The Locos, and an associate of Nick. Julio first falls under Dexter's radar after he comes to Brother Sam's Garage looking for Nick, with the threat of death if Sam doesn't give Nick over. Dexter acts quick, hitting Leo Hernandez with a baseball bat and revealing to the gang that he is with Miami Metro Homicide. Julio and his boys retreat, but not before Julio mentions Hector Nunez, and how he was never found. Dexter then abducts Julio, and kills him in Hector's barber shop by slitting his throat.
  • Walter Kenney - Walter Kenney was the notorious serial killer "The Tooth Fairy", who killed fifteen prostitutes during the eighties in the state of Oregon. The Tooth Fairy fell under Dexter's radar after the discovery of Rosalia Dabolos' body. Dexter, knowing that the killer would be at least seventy years old, first investigated the retirement home. After briefly distracting the receptionist, he searched the database for residents from Oregon, and came across Walter Kenney. Shortly after, he meets Walter, and discovers that he's missing his lateral incisor, which is the same tooth removed from all of The Tooth Fairy's victims. But before Dexter can abduct him, Walter becomes aware of the fact Dexter is associated with the police, and lures him into his own trap. He calls Dexter to pick him up, and after he does, Walter pulls a gun on Dexter. Dexter thinks quick, however, crashing the car, which knocks Walter out, and then takes him back to his own room in the retirement home. Rather than going through the normal routine with Walter, Dexter decides to smother him, to make it look like a heart attack, and afterwards dumps his "trophies" of teeth into the ocean, so nobody will ever know he was "The Tooth Fairy", thus destroying his legacy.
  • Nick - Nick was an associate of Brother Sam, who worked at his garage. Dexter targeted Nick after realizing that Eli, the dog Brother Sam kept around the garage, didn't bark at Brother Sam's shooter, which is what it did to anyone but Nick and Sam. Dexter goes to the hospital before going after Nick, assuring him that he knows who shot him and that he will take care of it. But Sam asks Dexter to "just let go", and forgive Nick for shooting him. Sam dies shortly afterward, and Dexter goes for a walk with Nick, next to the very area where Sam baptized him. It is here that Dexter tells Nick he knows he shot Sam, and that Sam has died. While at first Nick seems hurt by the news, he becomes relieved upon realized his only witness is dead. After showing joy at the fact he won't be caught, Dexter goes into a fit of rage, and drowns Nick in the ocean, the same place he was baptized and the same place where Brother Sam's ashes would be scattered.
  • Norm - Norm was the owner of a motel, and drug dealer in Nebraska. Dexter never intended to kill him, but was forced to in self-defense after he held a gun on Dexter and demanded $10,000 before he would return his knives. Brian Moser grabbed a nearby pitchfork off of the wall, and stabbed Norm in the stomach with it, though in reality it was Dexter who stabbed him.
  • Steve Dorsey - Steve Dorsey was a follower of Travis Marshall, The Doomsday Killer. Like Norm, Steve was not one of Dexter's intended targets. Dexter went to the Ricochet Rabbit with the intentions of killing Travis, though was bewildered upon seeing a man he believed to be Travis in a hazmat suit. Dexter got on the yacht, and attempted to quietly sedate the man, but the man detected Dexter, and a struggle ensued. During the struggle, Dexter got a knife, and stabbed the man in the abdomen. He threw the man to the floor, and then took the mask off, seeing that this man was not Travis Marshall, but instead Steve Dorsey. Dorsey tells Dexter that he is too late to stop Wormwood, and then dies on the floor of the yacht.
  • Beth Dorsey - Beth Dorsey was the wife of Steve Dorsey and another follower of Travis Marshall. Beth fell under Dexter's radar moments before her death, after he saw a picture of her with Steve Dorsey on a social networking website. Realizing that the bomb Wormwood was in the backpack strapped to her back, he rushed out of his lab to her. Debra opens the door to an interview room, and then Dexter shoves Beth in, just seconds after she sets the gas bomb off. He then slams the door shut, and holds it closed while Debra gets the station cleared. Beth attempts to escape the room, or at least get Dexter to open the door, but fails, vomiting blood on the window and eventually dying.
  • Alberto - Alberto was a man who, along with several others, pulled Dexter onto the boat. Although Alberto saved Dexter's life, his death became necessary after he pulled out a gun and told all passengers to put anything of value into his hat. Dexter, acting quickly, grabbed a harpoon and plunged it into his stomach, throwing him into the ocean.
  • Travis Marshall - Travis Marshall was the main antagonist of the season, and the "Doomsday Killer", who killed nine people during the season, though twelve over all. Travis was killed in Santa Maria de Laredo, an old church which served as his base of operations.
