Dexter: Original Sin Season 1 Finale – What to Expect
The highly anticipated season finale of Dexter: Original Sin drops this Friday, and tensions are at an all-time high. With shocking revelations and intense build-up from the previous episodes, multiple characters find themselves in grave danger.
Miami Metro’s Captain Aaron Spencer – The First Big Bad
Episode 7, titled "The Big Bad Body Problem," revealed a major twist: Miami Metro’s Captain Aaron Spencer is behind the murder of Jimmy Powell and the kidnapping of his own son, Nicky.
The NHI Killer – A Second Big Bad Emerges
Unlike the original Dexter series, Original Sin introduces another major villain: the NHI Killer. Labeled a serial killer by Dexter and LaGuerta, this mysterious figure targets victims and leaves their bodies scattered around Miami.
After traveling to Tampa for leads on the NHI case, Harry Morgan makes a shocking discovery—Brian Moser, Dexter’s long-lost brother, is the man behind these gruesome murders.
Brian Moser’s Return – The Bloodbath Begins
Episode 8, "Blood Drive," confirmed that not only is Brian Moser the NHI Killer, but he has also committed numerous other crimes while managing to evade capture. Brian is more ruthless than ever, and he’s on a path of vengeance.
Brian’s Revenge – A Killing Spree Begins
Since his brief cameo in Episode 2, fans speculated that Brian Moser would play a larger role in Dexter: Original Sin. Episode 9 confirmed these suspicions, as Brian embarked on a killing spree, seeking revenge against those who separated him from Dexter. His latest victim? A retired social worker who took him away after Harry and Doris Morgan’s fateful decision.
Brian’s brutal execution of the social worker mirrors the tragic death of Laura Moser, adding another eerie layer to his vendetta.
Is Harry Morgan Brian’s Next Target?
Fans are buzzing with speculation: is Brian coming for Harry next? Given his clear motives and deep-seated resentment, all signs point to a final showdown between the two. Harry played a pivotal role in separating Brian and Dexter back in 1973, and Brian seems determined to make him pay.
Episode 10 Teases a Face-Off Between Harry and Brian
Showtime’s official synopsis for the season finale hints at an explosive confrontation: “Harry comes face-to-face with a serial killer.” While Brian’s name isn’t mentioned directly, it’s clear that the showdown between Harry and Brian is inevitable. But will this battle lead to Harry’s demise?
How the Original Dexter Series Shapes Original Sin
In Dexter Season 2, Dexter initially believed Harry died of heart complications. However, after a revealing conversation with Matthews, he learned that Harry actually took his own life—a tragic consequence of Dexter’s actions.
Fans Theorize That Harry Morgan Didn't Take His Own Life
With new revelations from Dexter: Original Sin, fans are questioning the long-standing belief that Harry Morgan took his own life. The events following Laura Moser’s death have led many to speculate that Harry’s demise wasn’t self-inflicted, as suggested in the original series, but rather a calculated act of revenge by Brian Moser. While this remains just a theory, it adds an intriguing layer to Dexter’s backstory.
Will Harry Die in the Original Sin Finale?
In the original Dexter series, Harry Morgan passed away a year after surviving both a heart attack and an attempted murder by Nurse Mary. Since Dexter: Original Sin takes place shortly after his hospital release, Harry should have at least ten more months to live. This implies that while Brian may target him, Harry is unlikely to meet his end in the Season 1 finale.
Clyde Phillips on Harry’s Future & Christian Slater’s Portrayal
During a press interview in early December following the Dexter: Original Sin premiere, showrunner Clyde Phillips shared his intention to keep Harry alive as long as possible. His goal is to explore the pivotal relationship between Harry and Dexter before Harry becomes the guiding "ghost" figure seen in Seasons 3–8 of the main series. This strongly suggests that if Dexter: Original Sin gets a Season 2, it will likely delve into the final months leading up to Harry’s eventual death.
With Dexter: Original Sin delivering high-stakes drama and shocking twists, the upcoming finale promises to be an unforgettable showdown. Stay tuned!
