WARNING: SPOILERS ahead for Dexter: Original Sin episode 1.
The Dexter prequel series Dexter: Original Sin includes Doris Morgan, Dexter’s step-mom and Deb’s biological mom, in a tragic flashback scene in its pilot episode. Developed by New Blood creator Clyde Phillips, the prequel series chronicles a post-college Dexter as he embraces his “dark passenger” through the guidance and teachings of his adopted father, Harry. Dexter implements Harry’s code to satisfy his violent urges while making sure never to get caught.
After Michael C. Hall reprised his iconic role as the charismatic vigilante serial killer in 2021’s Dexter: New Blood, he returns as Dexter’s inner voice and narrator in the prequel series. The series takes place in Miami in 1991 as Dexter begins his career at Miami Metro PD. Dexter: Original Sin will likely cover a few anticipated kills that are already established in Dexter’s lore. Another upcoming Dexter series, Dexter: Resurrection, is expected to be released in the summer of 2025 with Hall also slated to return.

Doris Morgan Died From Cancer When Dexter Was In High School
Dexter was 16 and Deb was likely in middle school
Doris Morgan died from cancer when Dexter was still a teenager in high school, meaning that Deb was likely in middle school. There is not much information known about Doris Morgan as her character is hardly ever mentioned in the original series and has so far only been briefly included in the Original Sin premiere episode. Dexter did not appear to have a very close relationship with Doris but Deb was certainly old enough to know her mother before she passed.

The Dexter: Original Sin premiere may be overstuffed & uninsightful but it aptly sets up a killer leading duo in Gibson & Hall’s shared protagonist.
Doris Morgan is portrayed by Jasper Lewis in a flashback scene in Dexter: Original Sin episode 1, “And in the Beginning…”. In what is one of the biggest backstory reveals of the premiere prequel episode, Harry and Doris lost a child who drowned in their backyard pool at their home. It’s unclear how old Deb was when that happened or if she was even alive at that time. Harry and Doris took Dexter in even after Harry had an affair with Dexter’s mom, Laura Moser.
Did Dexter’s Adoptive Mom Know About The Code Of Harry?
Harry probably kept it a secret like he did with Deb
It is unclear at the time of writing how much Doris Morgan will be featured in Original Sin’s flashback scenes. The fact that she and Harry lost a son provides additional context around their adoption of Dexter. It’s also undetermined how close Doris and Dexter were throughout his adolescence. Odds are that they weren’t very bonded. It would be shocking if Dexter: Original Sin revealed that Doris knew about Dexter’s Dark Passenger and Harry’s Code before her death in future episodes. Harry likely kept it a secret like he did with Deb all those years.
Dexter: Original Sin explores the origins of Dexter Morgan as he transitions from student to serial killer in 1991 Miami. Guided by his father, Dexter channels his dark urges through a moral code while starting a forensics internship at the Miami Metro Police Department.
