Every Actor Who’s Played Dexter’s Son, Harrison, in Chronological Order

by

Dexter Morgan is a unique character on television. By day, he analyzes blood spatter as a forensic scientist, but he secretly leads a double life as a vigilante killer. Despite this, he’s also a father, and watching him try to balance these drastically different worlds is what made the show so captivating. It wasn’t just about the crimes or his personal rules; it was about a man struggling to create a normal life while battling his inner demons. His son, Harrison Morgan, also becomes a deeply compelling and emotionally complex character throughout the series.

From the very beginning, Harrison’s life is marked by tragedy. After his mother, Rita, is tragically killed, he becomes central to the show’s themes. He represents Dexter’s past trauma and challenges his attempts at being human. The series constantly asks whether Harrison will follow in his father’s dark footsteps or forge a different path. Though often in the background during the original series, Harrison frequently influences Dexter’s choices.

When the show Dexter returned as Dexter: New Blood, Harrison reappeared as a teenager, carrying his own hidden past. Since the series spans several years (and more than a decade in real time), different actors have portrayed Harrison at various ages. Each actor has brought a unique perspective to the character, from his earliest appearances as a baby to his portrayal as a young adult. Now, as Dexter: Resurrection continues Harrison’s journey, it’s a good moment to revisit his story.

Here is every actor who’s played Dexter’s son, Harrison Morgan, in chronological order.

Various Uncredited Infants

‘Dexter’ Season 4


Showtime

Before Harrison Morgan became a speaking character with his own problems, he was a baby, played by several unnamed infants during the fourth season of Dexter. It’s common for TV shows to use multiple babies when portraying newborns and very young children, as it allows for more flexibility during filming. Harrison is first seen in Season 4, as the son of Dexter and Rita, and though the babies who played him weren’t credited, they were important because his birth marked a major change in Dexter’s life – he went from being a serial killer to a father dealing with the challenges of parenthood and his dark impulses.

Watching the show, I was really struck by how important Harrison was, even as a baby. It wasn’t about him doing anything, but about what he represented. The final scene of Season 4, “The Getaway,” with Harrison in the blood… it was chilling. It instantly brought me back to Dexter’s own childhood, and it made me see Dexter’s whole journey in a new light. Having Harrison around actually made Dexter seem more human, and it forced him to start doubting everything he believed. Honestly, watching him as a baby made me wonder if someone raised in violence is ever truly free, and what it even means to be a father when you yourself can’t tell right from wrong.

Evan George & Luke Andrew Kruntchev

‘Dexter’ Season 5 to Season 7


Showtime

As Harrison Morgan grew into a more expressive toddler, twin actors Evan George and Luke Andrew Kruntchev took over the role. The Kruntchev twins, who often share roles, played Harrison from Seasons 5 to 7, helping to maintain a consistent portrayal of the character as he developed. Their work allowed Harrison to genuinely react to and interact with the complicated world around Dexter.

Watching Dexter grapple with fatherhood in the later seasons is really compelling. After Rita’s death, young Harrison becomes this incredibly complex symbol – a painful reminder of his loss, but also the one thing keeping Dexter from completely falling apart. The show brilliantly cuts between these tender moments of Dexter caring for Harrison – feeding him, giving him a bath, just being a dad – and his darker, violent urges. As the seasons progress, Dexter starts to worry about whether his own darkness will be passed down to his son, and Harrison’s presence becomes vital to that internal conflict. But by Season 7, Harrison evolves into something more than just a son; he’s Dexter’s last connection to normalcy, his anchor to humanity. He’s this innocent, playful kid completely oblivious to the dangerous world his father inhabits, but you can feel the tension building, the storm clouds gathering around them both.

Lucas Adams

‘Dexter’ Season 7


Showtime

While Lucas Brentley Adams is now famous for his work on Days of Our Lives, he had a small role on Dexter back in 2012. He played a teenage Harrison Morgan in the Season 7 episode “Do You See What I See?” It’s an interesting detail because, at the time, Harrison was mostly played by very young children, making Adams’ appearance as the seventeen-year-old version of the character a memorable moment.

In a dream sequence during a Christmas episode, Dexter imagines a future free from violence and deceit. He envisions his son, Harrison, as a happy, well-adjusted teenager enjoying a normal holiday dinner. The actor playing Harrison portrays him as calm, kind, and emotionally stable – a version of Harrison who hasn’t been burdened by past trauma.

The scene represents Dexter’s ideal vision for his son, Harrison – a childhood filled with safety, love, and ignorance of his father’s dark side. Ultimately, the scene isn’t about the details of what’s happening on screen, but the powerful emotions it evokes. This sequence lays the groundwork for events in Dexter: New Blood, and becomes even more meaningful when you consider how Jack Alcott later portrays a much different Harrison.

Jadon Wells

‘Dexter’ Season 8


Showtime

Six-year-old Jadon Wells played Harrison Morgan in the final season of Dexter, appearing in most of the episodes. He brought a lot more emotion to the character, making Harrison feel like a real, fully developed child – one with his own thoughts, feelings, and reactions – instead of just a plot device. Wells portrayed Harrison as bright, kind-hearted, and occasionally a little sassy.

The eighth season of Dexter focuses on Dexter’s internal struggle and growing sense of unease. He’s attempting to escape his dark past and build a new life with Hannah McKay and their son, Harrison, in Argentina. Harrison is the driving force behind Dexter’s desire for change. Throughout the season, we see touching moments of Harrison connecting with Hannah, questioning his father, and behaving like a typical four-year-old. The actor playing Harrison portrays him as a curious child trying to understand the complex world around him, which heightens the emotional impact of Dexter’s journey.

Jadon Wells delivered a truly memorable performance this season. As Harrison, he was the last person Dexter interacted with before going into hiding, and Wells played the role so convincingly that Dexter’s decision to abandon fatherhood felt especially powerful. This performance also sets the stage for Dexter: New Blood, where Harrison reappears as a troubled teenager seeking answers.

Jack Alcott

‘Dexter: New Blood,’ ‘Dexter: Resurrection’


Showtime

For those who watched both the original Dexter series and its revival, New Blood, Jack Alcott’s performance as Harrison Morgan was truly remarkable. He didn’t just play the character – he completely embodied him, making it feel like he was Harrison. Alcott had already impressed audiences in The Good Lord Bird alongside Ethan Hawke, and he brought a powerful intensity to the role of Dexter’s teenage son right from the start. His portrayal felt like a fresh, updated take on the character, adding significant emotional depth.

For years, Harrison was a background character – either a small child, a fleeting idea, or simply a tool to move the story forward. But Alcott gave him real power, emotions, and the ability to speak his mind. And it wasn’t just any voice; it was strong and assertive enough to question Dexter’s principles, expose his flaws, and ultimately make the show examine its own narrative.

The new season, Dexter: New Blood, begins with Harrison appearing in Iron Lake, New York, determined to find his father, Dexter, who disappeared years ago. It’s been almost a decade since Dexter went missing, and Harrison’s arrival sets the main story in motion. Actor Jack Alcott portrays Harrison as a resilient kid who has faced a lot of hardship. He’s likable, physically capable, and intelligent, but clearly haunted by the loss of his mother, Rita, and Hannah McKay, as well as a long-held feeling that something isn’t quite right. As Dexter gets to know Harrison, he starts to recognize familiar traits and worries that he may have passed on more than just his genes.

The series culminates in a shocking yet fitting finale where Harrison appears to kill Dexter, not in anger, but with a clear understanding of what needs to be done. Michael C. Hall delivers a powerfully honest performance, and the scene of Dexter asking for death, and Harrison granting it, has stayed with viewers ever since. It marks the end of Dexter’s story, but also the start of a new one, as seen in Dexter: New Blood, where Harrison joins his father for a fresh set of violent adventures. In this new chapter, Harrison grapples with the same dark impulses that plagued Dexter, forcing him to confront the central question of the series: can someone raised in a world of violence ever truly escape it?
