“Dexter: Original Sin” has shown Dexter Morgan’s (Patrick Gibson) first kill and how he gradually became a full-fledged serial killer. The series effectively builds up to the version of Dexter that fans loved in the original show.
It does this while also providing important details about his past and the people who played key roles in shaping his life. This prequel series has introduced more backstory for characters who were significant in both Dexter’s past and future.
As the story unfolds, another serial killer steps into the spotlight—Dexter’s brother, Brian Moser (Roby Attal), also known to fans as the Ice Truck Killer.
The series has quietly hinted that Brian is the N.H.I. (No Humans Involved) Killer. However, when the case involving the kidnapped children of a judge and Captain Aaron Spencer (Patrick Dempsey) takes priority, Brian is able to continue his killings without being caught.
Why “Dexter: Original Sin” Is More Than Just Dexter’s Beginning
Many fans were unsure about “Dexter: Original Sin” when it was first announced. However, the show has proven its value by adding depth to Dexter’s story and filling in gaps from his past.
It also shows the history of his sister Deb (Molly Brown) and his adoptive father Harry (Christian Slater). The series provides insight into how Harry not only guided Dexter’s dark urges but also decided to raise him as his own child after a tragic event.
The introduction of Dexter’s brother Brian surprised many viewers, especially knowing that Brian would later become the main villain of “Dexter” Season 1.
Watching Brian’s transformation into a killer, mirroring Dexter’s own path is a fascinating way to expand the original series. “Dexter: Original Sin” carefully examines the similarities and differences between the brothers.
Dexter’s killing style in the prequel closely resembles what fans saw in the original show. However, Brian experiments with different methods before settling on his final approach as the Ice Truck Killer.
Dexter begins to notice patterns in the victims, realizing that the killer is testing different techniques to see which one he prefers. This investigation catches the attention of both Harry and Detective Maria LaGuerta (Christina Milian), leading them to pursue the case further.
A Childhood Marked by Trauma
Season 1, Episode 9, titled “Blood Drive,” reveals how the Shipping Yard Massacre shaped Dexter and Brian’s lives. Their mother, Laura Moser (Brittany Allen), was brutally murdered in front of them, leading to their adoption by Harry and Doris Morgan (Jasper Lewis).
In “Dexter,” flashbacks showed both boys as infants when they were rescued. However, “Dexter: Original Sin” corrects this, showing that they were actually around seven years old. This makes their trauma even more intense. The brothers react to the horror in different ways. Dexter becomes completely silent, refusing to speak, while Brian struggles with anger.
Brian’s violent tendencies become clear when he tries to suffocate baby Deb with a pillow. He also lashes out at Harry in a violent outburst. After this, the Morgans make the difficult choice to separate the brothers. This moment is life-changing. Oddly, it causes Dexter to finally speak again, but it also pushes Brian toward a future of anger and violence.

Brian’s Path of Revenge and Darkness
“Dexter: Original Sin” provides a closer look at Brian’s personal journey, showing how his need for revenge fuels his violent behavior. He blames Harry for taking him away from his brother and for the tragic death of their mother. Brian sees Harry as the reason why his family was torn apart.
While Dexter forms a bond with Harry over time, Brian never does. He watches as Harry and his mother grow close while working on the Estrada case. When Laura dies, Brian sees it as Harry’s fault. He is left alone while Dexter is raised in a loving home, which only deepens his resentment.
Brian’s feelings of betrayal push him further down a dark path. He holds a deep hatred for those who separated him from Dexter. His killings are not random. They are driven by a desire for revenge against those who failed him.
Did Brian Have a Role in Harry’s Death?
Harry’s eventual death has always been a mystery, but “Dexter: Original Sin” raises new questions about it. Fans have long believed that Harry took his own life, but new details suggest that Brian may have played a role.
The show has done an excellent job of showing how Dexter’s secret activities take a toll on Harry. However, nothing in the series suggests that Harry was willing to end his own life.
As Harry investigates the N.H.I. Killer case, he begins to realize that Brian is the murderer. He also discovers that Brian has been stalking Dexter ever since he started working for Miami Metro Forensics. If Harry puts all the pieces together, Brian could see him as a threat.
Brian has already started eliminating people from his past. He brutally killed Barb (Kathleen Rose Perkins), the social worker who promised to keep the brothers together. He used a chainsaw, mirroring the way he saw his mother being murdered.
Since Deb’s mother died of cancer, it is unlikely that Brian targeted her. However, Harry is at the top of Brian’s list of people who wronged him. If Brian is responsible for Harry’s death, it would be a major revelation.
What’s Next for Brian, Dexter, and Deb?
Deb plays a major role in Dexter’s life, particularly during the Ice Truck Killer storyline. This makes it unlikely that Brian will harm her anytime soon. Instead, Brian seems to be waiting for the right time to act.
The series has set up an intense finale, and Brian’s role in the story is more important than ever. He is playing a long game, carefully planning his next moves. The tension continues to rise, and fans are eager to see what happens next.
“Dexter: Original Sin” is not just a simple prequel. It adds depth to the original series and brings fresh surprises. The relationship between Dexter and Brian is one of the most complex and gripping aspects of the show. With so many possibilities ahead, fans are left wondering what twists will come next.
The first season has built up an exciting and suspenseful story. If future seasons continue to show Brian’s journey, it could lead to even more shocking moments. Fans will have to wait and see what happens as “Dexter: Original Sin” reaches its climax.
