Dexter Morgan isn’t your average TV dad. He is a forensic blood spatter analyst with a side hustle as a vigilante serial killer, and somehow, he’s also raising a son. That balancing act is what made Dexter so addictive to watch. It wasn’t just the kills or the code. It was watching a man with a monster inside him trying to rebuild a life that looked normal on the outside. And speaking of Dexter’s son, Harrison Morgan quietly becomes one of the most emotionally loaded characters in the entire franchise.
Harrison starts out as a baby, but he’s born into a world that’s already soaked in blood. His mother, Rita, is murdered in one of the show’s most devastating season finales, and from that moment on, Harrison becomes a symbol of everything the show stands for. He’s a reminder of Dexter’s trauma, a test for his humanity, and eventually a question mark. Will Harrison inherit his father’s darkness, or will he break the cycle? Harrison is present throughout the original series, something in the background and sometimes responsible for Dexter’s life decisions.
And when the franchise returns years later in Dexter: New Blood, Harrison comes back as a teenager with his own secrets. Because Harrison grows up over the course of the series (and across more than a decade of real-world time), he’s been played by multiple actors. From uncredited infants to fully fleshed-out teenagers, each version brings something new to the character. And now, with Dexter: Resurrection continuing Harrison’s story, it’s the perfect time to look back.
Here is every actor who’s played Dexter’s son, Harrison Morgan, in chronological order.
Various Uncredited Infants
‘Dexter’ Season 4
Before Harrison Morgan became a character with dialogue and dilemma, he was a baby, played by various uncredited infants across Dexter’s fourth season. This is a standard practice in television, especially when depicting newborns and very young children, due to the need for flexibility on set. Harrison first appears in Season 4, born to Dexter and Rita, and while the babies portraying him aren’t named in the credits, their presence is foundational because they mark a turning point in Dexter’s life, turning him from a predator to a man juggling diapers and dark urges.
These infants didn’t perform in the traditional sense, but their role was symbolic. Season 4’s finale, “The Getaway,” delivers a haunting image where Harrison is sitting in a pool of his mother’s blood. The scene echoes Dexter’s origin story, and the visual callback reframes his entire arc. Harrison’s presence also helped humanize Dexter and gave him a reason to question his code. Overall, Harrison’s infancy period raised questions like, can someone born in blood escape it? And what does fatherhood mean when your own moral compass is skewed?
Evan George & Luke Andrew Kruntchev
‘Dexter’ Season 5 to Season 7
When Harrison Morgan turned into a toddler with a little more personality and presence, twin actors Evan George and Luke Andrew Kruntchev stepped in. Known for sharing laws, the Kruntchev twins portrayed Harrison from Seasons 5 through 7, bringing a sense of continuity to the character’s early development. Their performance allows Harrison to react, emote, and interact with Dexter’s complex world.
This version of Harrison appears during a transition period. Dexter is reeling from Rita’s death at the beginning of Season 5, and Harrison is both a reminder of that trauma and a reason to keep going. Scenes of Dexter feeding, bathing, and comforting Dexter are juxtaposed with his return to killing. In Season 6, Harrison’s presence is necessary because Dexter is starting to question whether his son might inherit his darkness. By Season 7, Harrison is more than just Dexter’s son. He’s his tether to humanity. Harrison is playful and innocent, and unaware of the storm brewing around him. But there’s a storm brewing nonetheless.
Lucas Adams
‘Dexter’ Season 7
Lucas Brentley Adams is best known for his later work on Days of Our Lives, but in 2012, he briefly hopped into the world of Dexter as a teenage version of Harrison Morgan. He’s credited only in the Season 7 episode “Do You See What I See?” but it’s a curious footnote. At the time, Harrison was still portrayed primarily by toddler actors, so Adams’ role as “Seventeen-Year-Old Harrison” is a moment worth noting.
Adams’ appearance comes in a dream sequence of an imagined future that unfolds during a Christmas-themed episode, where Dexter thinks of a life untouched by blood and betrayal. In this future, Harrison is a well-adjusted teen, sitting at a holiday dinner table, surrounded by normalcy. Adams plays him as a calm, kind, and emotionally grounded person. There’s no trauma lurking beneath the surface in this version of Harrison.
It’s Dexter’s fantasy of what Harrison could be. A son who grows up safe, loved, and unaware of his father’s secret life. So in the end, it’s not about screen time, but about emotional resonance. Adams’ portrayal plants the seeds that would later bloom in Dexter: New Blood. And the dream sequence becomes more poignant in hindsight when contrasted with Jack Alcott’s portrayal of Harrison years later.
Jadon Wells
‘Dexter’ Season 8
Six-year-old Jadon Wells took over the role of Harrison Morgan in Dexter’s eighth and final season, appearing in nearly every episode. Wells brought a more expressive version of the character to the screen. His performance also marked the first time Harrison felt like a proper part of Dexter’s life, instead of just a symbol or a side note. He was a child with reactions, needs, and a growing awareness of the world around him. Wells’ Harrison is precocious, sweet, and sometimes sharp.
Season 8 of Dexter is all about unresolved tension and existential dread. Dexter is trying to leave behind his life of killing, planning a future with Hannah McKay and Harrison in Argentina. Harrison is central to this dream because he’s the very reason Dexter wants to change. Scenes of Harrison bonding with Hannah, asking questions about his father, and simply being a four-year-old are scattered across the season. Wells’ plays him as a child, trying to make sense of the adults around him, which makes Dexter’s arc all the more painful.
Jadon Wells deserves a shoutout for the impact his acting had on the season. His version of Harrison is the last we see before Dexter fakes his death and disappears. And because his performance is so good, Dexter choosing isolation over fatherhood hits harder. It also raises the stakes for Dexter: New Blood, where Harrison returns as a teenager with questions, trauma, and scars.
Jack Alcott
‘Dexter: New Blood,’ ‘Dexter: Resurrection’
If you stuck with Dexter through its original run and then came back for New Blood, you know that Jack Alcott didn’t just play Harrison Morgan, he cracked the character wide open and made it seem like he’d been living in Harrison’s skin for years. Alcott, who had already made a mark in The Good Lord Bird opposite Ethan Hawke, stepped into the role of Dexter’s teenage son with the kind of intensity that worked immediately. His version was a physical update and an emotional upgrade.
After years of Harrison existing in the margins, being a toddler, a dream, or a plot device. Alcott gave him agency, anger, and a voice. And not just any voice, but a voice strong and loud enough to challenge Dexter’s code, call out his hypocrisy, and force the show to confront its own plot.
In Dexter: New Blood, Harrison shows up in Iron Lake, New York, looking for the father who abandoned him. It’s been nearly ten years since Dexter dipped, and Harrison’s arrival is an engine for the revival. Alcott plays him like a kid who has been through too much but refuses to break. He is charming, he is athletic, and he’s smart. But there’s a hint of trauma about losing his mother Rita, the death of Hannah McKay, and the years of feeling like there was something wrong with him. And it’s more apparent when Dexter starts to see pieces of himself in Harrison and wonders if he’s passed on more than just DNA.
And then comes the finale, where Harrison seemingly kills Dexter. Not out of rage, but out of clarity. The moment is shocking and inevitable, and Alcott is heartbreakingly honest in his portrayal. That scene where Dexter asks for death and Harrison delivers it lives rent-free in the minds of fans across the world. It’s the end of one story and the beginning of another. Which brings us to Dexter: Resurrection, where Alcott returns alongside his dad for bloody new capers. Here, Harrison must also navigate the code, the guilt, and the question that has haunted the franchise from the start: Can someone born in blood escape it?
