Dexter: Original Sin Is Set In 1991, 15 Years Before The Original Show
The Dexter prequel is technically a period piece
Dexter: Original Sinwill take place in 1991 in Miami, which is exactly 15 years before the show premiered on Showtime in 2006. As such, Dexter Morgan will be played by a younger actor Patrick Gibson who is just getting started in his CSI career as a blood spatter analyst at Miami Metro PD. It will be the first time that the audience gets to see Harry Morgan on screen while that character is living outside of various flashback scenes and appearances as a part of Dexter’s conscience. The time period will reflect the culture and sentiments ofthe early 1990s, makingDexter: Original Sina modern period piece.
Dexter: Original Sinwill bring back the original characters of Angel Batista, María LaGuerta, and Vince Masukaand chronicle their early days at Miami Metro PD. TheDexterprequel series also recently castPatrick Dempsey of Grey’s Anatomyfame as a new character in the story world, Police Captain Aaron Spencer. The series will likely dive into the relationship between Dexter and Harry and how Harry was able to maintain Dexter’s violent urges through his code, since Harry will already be well aware of Dexter’s Dark Passenger inOriginal Sin. It alsoraises the question of whether Dr. Evelyn Vogel will make an appearancesince she designed the code with Harry.

After 15 Years, Dexter’s New Spinoff Has A Nearly Impossible Challenge From The Original’s Highest-Rated Episode
Dexter: Original Sin will be the first series of the franchise to recast its titular protagonist, making it even harder to outdo Dexter’s best season.
Dexter: Original Sin Begins One Year After Doris Morgan’s Death
Both Doris Morgan & Laura Moser are cast in the Dexter prequel
Dexter: Original Sinwill begin one year after the death of Harry’s wife and Debra’s biological mother, Doris who will be played by Jasper Lewis (V/H/S) in the prequel series. This detail was confirmed by Clyde Phillips at SDCC 2024. Dexter’s biological mother, Laura Moser, will also appear in the series, portrayed by Brittany Allen (The Boys,Falling Water).Both of Dexter’s mothers will still be deceased at the start ofDexter: Original Sin, as in the original series, considering that Laura Moser was brutally murdered with a chainsaw in a freight container when Dexter and his brother Brian (The Ice Truck Killer) were born.
Doris Morgan is referenced through all eight seasons of the original series but mostly as a supporting character to Harry Morgan, played by James Remar. Dexter does not have a close relationship with either of his mothers buthe would certainly have had spent much more time with Doris than he would have with Laura, since Laura died before Dexter could even speak. Doris Morgan was portrayed by Kathrin Middleton in two episodes of the first season, one episode in the second season, and the season 7 premiere, all through flashback sequences. It’s unclear how her death will affect the younger Dexter inOriginal Sin.

Christian Slater’s Dexter Prequel Casting Is Ironic After His 95% RT Cult Classic Movie From 35 Years Ago
Christian Slater will appear as Harry Morgan in the upcoming prequel series Dexter: Original Sin, which bears a resemblance to a classic 1989 film.
How Old Dexter & Debra Morgan Are In Original Sin
Dexter is in his early twenties & Debra may be an older teenager
Dexter Morgan was 35 during the first season ofDexter, which is the same as actor Michael C. Hall. WhenDexterended in 2013, the titular protagonist was 41 years old due to the fact that the events of the final season took place in 2012. Interestingly,Patrick Gibson, who is slated to take on the role of Dexter Morgan in the prequel series, is 29 years oldas of the time of writing, which makes a 9-year age gap between his actual age and the age of the younger Dexter Morgan. The creators ofDexter: Original Sinare clearly not concerned by the age difference.
Debra Morgan was 26 inDexterseason 1, meaning technically speaking, her character should be 11 years old in 1991 whenDexter: Original Sinwill take place. Actress Molly Brown is estimated to be in her early twenties, so it appears thatDexter: Original Sinwill be making some adjustments to the age gap between Debra and Dexter Morgan. It would be ridiculous if Brown tried to pass as someone high school-aged younger than 17, which is already a stretch, so as of now her character in Dexter: Original Sin is predicted to be around 17 or 18 years old.

After Dexter: New Blood’s Ending, I Appreciate The Original Finale A Lot More
Dexter’s final episode has been criticized as one of the worst series finales in modern television, but New Blood’s ending might actually be worse.
How Long Before Dexter: New Blood Does Original Sin Take Place?
Original Sin takes place roughly 30 years before Dexter: New Blood
Dexter New: Bloodtakes place ten years after the finale of the originalDexterseries, even though in reality it was released 8 years later rather than 10. The originalDexterseries ended in 2013, whileDexter: New Bloodwas released in 2021. While it’s not precisely correct in the chronology, the minimal two-year difference has zero effect on either of the established Dexter series. However, considering thatDexter: Original Sintakes place fifteen years before the original series starts and 22 years after the original series ends, it’s safe to say thatOriginal Sintakes place roughly 30 years before the events ofDexter: New Blood.
With the new information thatDexter: Resurrectionwill extend Dexter’s story even further into the future after he presumably died in both teh original Dexter series and inDexter: New Blood, it will be quite interesting to instead go back in time to explore the origins of the character inDexter: Original Sin. WhileNew Bloodwas an exciting first step in expanding the greaterDexteruniverse, it was also an experiment that ended an 8-year silence about whether the acclaimed series would ever be revisited again. After theDexter: Original SinSDCC 2024 panel, Dexter fans truly have something to be excited about.
