Dexter: Original Sin Is Set In 1991, 15 Years Before The Original Show

The Dexter prequel is technically a period piece

Dexter: Original Sin will 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 of the early 1990s, making Dexter: Original Sin a modern period piece.

Dexter: Original Sin will bring back the original characters of Angel Batista, María LaGuerta, and Vince Masuka and chronicle their early days at Miami Metro PD. The Dexter prequel series also recently cast Patrick Dempsey of Grey's Anatomy fame 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 enger in Original Sin. It also raises the question of whether Dr. Evelyn Vogel will make an appearance since she designed the code with Harry.

Dexter: Original Sin Begins One Year After Doris Morgan's Death

Both Doris Morgan & Laura Moser are cast in the Dexter prequel

Dexter: Original Sin will 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 of Dexter: 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 ing character to Harry Morgan, played by James Remar. Dexter does not have a close relationship with either of his mothers but he 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 in Original Sin.

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 of Dexter, which is the same as actor Michael C. Hall. When Dexter ended 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 old as 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 of Dexter: Original Sin are clearly not concerned by the age difference.

Debra Morgan was 26 in Dexter season 1, meaning technically speaking, her character should be 11 years old in 1991 when Dexter: Original Sin will take place. Actress Molly Brown is estimated to be in her early twenties, so it appears that Dexter: Original Sin will be making some adjustments to the age gap between Debra and Dexter Morgan. It would be ridiculous if Brown tried to 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.

How Long Before Dexter: New Blood Does Original Sin Take Place?

Original Sin takes place roughly 30 years before Dexter: New Blood

Dexter New: Blood takes place ten years after the finale of the original Dexter series, even though in reality it was released 8 years later rather than 10. The original Dexter series ended in 2013, while Dexter: New Blood was 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 that Dexter: Original Sin takes place fifteen years before the original series starts and 22 years after the original series ends, it's safe to say that Original Sin takes place roughly 30 years before the events of Dexter: New Blood.

With the new information that Dexter: Resurrection will extend Dexter's story even further into the future after he presumably died in both teh original Dexter series and in Dexter: New Blood, it will be quite interesting to instead go back in time to explore the origins of the character in Dexter: Original Sin. While New Blood was an exciting first step in expanding the greater Dexter universe, it was also an experiment that ended an 8-year silence about whether the acclaimed series would ever be revisited again. After the Dexter: Original Sin SDCC 2024 , Dexter fans truly have something to be excited about.
