Dexter: Original Sin - Revealing the ages of Dexter, Harry, Debra and other pivotal characters in the Paramount spin-off

Dexter: Original Sin takes fans back to the '90s. It gives us a closer look at Dexter Morgan's early life and important relationships from the original series. This prequel shows Dexter in college and starting his career as a forensic intern.

His sister, Debra, is around 17 or 18, even though she should be 11 at this time. Their father, Harry, stays the same age, 53, which was his age when he passed away in the original storyline. Other characters from the original Dexter series also have their ages changed. For example, Angel Batista, Maria LaGuerta, and Vince Masuka look a bit younger in this new show.

Here's a breakdown of each character's age in Dexter: Original Sin.

How old are Dexter, Debra, and Harry Morgan in Dexter: Original Sin?

Dexter Morgan, a character from season 1 of Dexter, is shown as a 20-year-old college student in Dexter: Original Sin. The actor playing him, Patrick Gibson, is 29, almost 10 years older than the character's age in the story. Despite this, the people making the show are sure that Gibson can play a younger Dexter well.

Debra Morgan, Dexter's younger sister, was 26 when the original show started. This would mean she should be 11 in 1991. But in Original Sin, she's older, around 17 or 18. Molly Brown, the actress playing her, is in her early 20s. The show's creators probably did this to keep the relationship between the siblings more normal without a huge age difference.

Their adoptive father, Harry Morgan, was 53 when he passed away. This matches his age in the new show. Christian Slater now plays Harry, who was first played by James Remar. Slater is 54, so he's the right age for the role.

So, even though the actors are older than their characters, the show keeps the family's ages closer together to make the story feel more realistic and maintain their bond as siblings and father.

Ages of Batista, LaGuerta, and Masuka on Dexter: Original Sin

In the first season of Dexter, Angel Batista, portrayed by David Zayas, was 44 years old. This would make him 29 in the prequel, Dexter: Original Sin. However, James Martinez, the actor who plays the younger version of Batista, is 37. This small age increase in the prequel may be to make the character more believable.

Maria LaGuerta, originally played by Lauren Vélez, started the main series at 42. This would place her at 27 in 1991, the setting of the prequel. But in Dexter: Original Sin, Christina Milian, who is also 42, takes over the role. She likely plays LaGuerta in her early 30s, which aligns with the age of the other characters.

Vince Masuka, Dexter's peculiar forensic analyst, was the same age as Dexter at 35 in the first season. Given the prequel shows Dexter at 20, Masuka should be the same. Alex Shimizu, the actor for the young Masuka, seems to be in his late 20s or early 30s. This makes him a suitable choice for younger Masuka.
