If you’re still thinking about that scene where Dexter Morgan stands on his porch in a silly Mickey Mouse hat while his stepchildren look at him with pure, unadulterated hatred—you aren’t alone. It’s one of the most haunting moments in the show. Not because of a blood splatter or a sharp knife, but because of the domestic wreckage left behind by the Trinity Killer.
When Rita died in that bathtub, the family unit didn't just break; it shattered and flew to opposite corners of Florida. While Harrison stayed in the spotlight to eventually become the brooding protagonist of Dexter: New Blood, his older siblings basically fell off the face of the earth.
So, what happens to Cody and Astor in Dexter?
Honestly, the answer is a mix of narrative convenience and a very cold, hard dose of reality. They didn't die. They weren't kidnapped. They just... moved to Orlando.
The Great Orlando Exodus
Let’s look at the facts. After Rita’s funeral in Season 5, the tension in that tiny apartment was suffocating. Astor was a grieving teenager who (rightfully) blamed Dexter for not being there to protect her mom. She wanted out.
The kids ended up moving to Orlando to live with their paternal grandparents—Paul Bennett's parents. It’s a detail people often forget. They didn't go to Rita's mother, who was also a bit of a piece of work. They went to the parents of their biological father.
A Quick Timeline of Their Disappearing Act:
- Season 5, Episode 2: Astor and Cody officially move to Orlando.
- Season 5, Episode 12: They briefly return to Miami for Harrison’s first birthday party. This is where Dexter and Astor have a rare moment of reconciliation. He beats up a local creep for her, and she finally realizes he does care in his own weird way.
- Season 7, Episode 8 ("Argentina"): This is the big one. They visit Dexter in Miami for a week. They’ve grown up. Cody is a giant; Astor is experimenting with "becoming an adult." It’s the last time we ever see them on screen.
Why the Writers Flushed Them Out
Look, from a storytelling perspective, kids are a nightmare for a serial killer protagonist.
You can’t exactly go out and dismember a human trafficker if you have to pick up a teenager from soccer practice or help with a science fair project. The writers needed Dexter to be "free" again. By shipping Astor and Cody off to Orlando, they kept Harrison (the baby who can’t talk or testify) and ditched the two people who were old enough to start asking why "Daddy" never sleeps and always smells like bleach.
It felt like a cheap move to a lot of fans. I get that. But in the world of the show, it was the only way to get back to the "monster of the week" format.
The New Blood and Resurrection Ghosting
Fast forward to the 2021 revival, Dexter: New Blood. Harrison shows up in Iron Lake, looking for his dad. He talks about his trauma. He talks about Rita. But Cody and Astor? Not a peep.
It’s bizarre.
Harrison is their half-brother. They shared a house. They shared a mother’s death. You’d think at some point Harrison would have Googled them or tried to find them. But the showrunner, Clyde Phillips, has been pretty blunt about this in recent interviews. In late 2025, leading into the hype for Dexter: Resurrection, he basically admitted they aren’t even "part of the conversation" in the writers' room.
Basically, as far as the creators are concerned, Astor and Cody are "living their lives" somewhere in Florida, completely disconnected from the bloodbath that is the Morgan family legacy.
Common Misconceptions:
- Did they die in the hurricane? No. They were safe in Orlando when Dexter drove his boat into the storm in the original series finale.
- Are they in foster care? No. They stayed with the Bennetts.
- Did they know Dexter was a killer? No. As far as they know, their stepdad was a nice, awkward lab geek who died at sea (and then turned out to be alive and a fugitive a decade later).
The Reality of the Bennett Kids Today
If we’re following the timeline of the show, Astor would be in her late 20s or early 30s by now. Cody wouldn't be far behind.
They are likely the only "normal" ones left from that era. While Harrison is out there dealing with his own "Dark Passenger" and Dexter is... well, being Dexter... Cody and Astor represent the life Rita wanted. A life away from the blood.
There's a lot of fan theory energy suggesting Cody might return as a villain or a vengeful hunter in Resurrection. While that would be "cool," it doesn't fit the show’s current trajectory. They weren't born in blood like Dexter and Harrison. They were just kids who got caught in the crossfire of a monster.
Honestly, the most realistic ending for them is that they’re just regular people. Maybe Astor is a lawyer. Maybe Cody is a gym teacher. They probably haven't spoken to Dexter in fifteen years, and frankly, that’s probably the best thing that ever happened to them.
What You Should Do Next
If you’re doing a rewatch or catching up before Resurrection drops, pay close attention to Season 5. It’s the last time the show actually treats them like characters instead of plot obstacles.
Next Steps for the Die-Hard Fan:
- Watch Season 7, Episode 8: It’s the definitive "goodbye" to these characters, even if we didn't know it at the time.
- Ignore the "Cody is the New Killer" theories: Unless the writers do a massive 180, these kids are officially civilian casualties of the narrative.
- Focus on Harrison’s transition: The show has clearly decided that Harrison is the only child of Dexter that matters to the "code."
They might be gone from the screen, but Cody and Astor remain the biggest reminder of the collateral damage Dexter Morgan leaves in his wake.
