TL;DR: Episode 6 of Dexter: Resurrection, titled “Cats and Mouse,” delivers the most jaw-dropping twist in the series so far. Dexter sets his sights on Gareth, the so-called Gemini Killer, and even gets him on his table—only to realize too late that Gareth has a twin. The Gemini Killer is literally Gemini. Meanwhile, Harrison is struggling with his dark urges but trying hard to do the right thing, and Dexter is genuinely trying to be a father for once. The emotional stakes rise, the bodies pile up, and Prater’s twisted dinner party of serial killers continues to be the most unnerving (and fascinating) ensemble in Dexter history.

Dexter Morgan and the Art of Trying Not to Murder Everyone

Somewhere between the ashes of Dexter’s past and the soft glimmers of fatherhood, Episode 6 of Dexter: Resurrectiondoes something most legacy reboots don’t even bother to attempt: it dares to evolve. Dexter’s new life is one half grief therapy, one half serial killer AA meeting, and somehow, it’s working.

We open with Dexter in his modest new apartment, engaging in the most wholesome conversation he’s probably ever had with a landlord. Blessing, mourning his adopted mother Prudence, gives the episode its emotional backbone. Their conversation is soft, vulnerable, human—exactly what this version of Dexter is trying so hard to fake, yet keeps stumbling into genuinely.

His reunion with Harrison deepens. The father-son scenes are tender in that awkward, repressed kind of way that only serial killers can pull off. Harrison shows up with a suit, and the two share a tie-tying moment that feels almost aggressively normal—until you remember the child has murder fantasies and the dad once drowned a pedophile in his own koi pond.

We even get a sweet flashback to Hannah, and Dexter, with real sincerity in his voice, apologizes to Harrison. It’s corny, sure, but it works.

The Dinner Party from Hell, Now with Helicopters

Leon Prater, played with icy charisma by Peter Dinklage, continues to be the smirking puppet master of this psycho-social experiment. His motley crew of serial killers feels less like a club and more like a Ted Talk panel on sociopathy. And now Dexter, under the guise of “Red,” is playing house guest.

But it’s not just brunch and body counts anymore. Mia, aka Lady Vengeance, has become a liability. Last episode, Dexter framed her for Harrison’s murder. Now she’s in jail, a ticking time bomb of vengeance and confusion.

Meanwhile, Batista is closing in. Slowly. Methodically. And with that good ol’ Miami Metro mix of intuition and plot-convenient dumb luck. He believes Dexter’s alive. He thinks Harrison did it. And he wants Mia to confirm it with a photo. Trouble is, she never gets the chance.

The Gemini Killer Gets Got… Or Does He?

Let’s talk Gareth. Played by David Dastmalchian with delicious creepiness, Gareth checks every box on Dexter’s kill code. Dexter finds a clue—an 8PM appointment scrawled inside a true crime book at a local bookstore—and follows Gareth, waiting for the perfect moment.

It comes. And it’s textbook Dexter: drugged drink, cool dialogue, and then—the table. The slide. The knife. One less killer in the world.

Except, no. The universe punches Dexter in the gut.

Because minutes later, when Dexter shows up for a weirdly luxurious helicopter meetup with Prater and friends, Gareth walks out of a car, very much alive.

And that’s when it hits: They’re twins.

The Gemini Killer was never one person. Dexter killed the wrong brother. This isn’t just a twist—it’s a narrative ambush. A twist so classically Dexter that you want to throw a remote at your TV and yell, “Of course they’re twins, you idiot!”

Harrison: Boy With Fork, Dreams of Violence

Harrison’s story this episode is quieter, but no less intense. He babysits for Elsa, and when her son has an asthma attack due to black mold in their apartment, Harrison shows an incredible amount of care.

Then the scumbag landlord Vinny shows up, demanding rent. Harrison fantasizes about driving a fork through the guy’s eye, but doesn’t act on it. It’s a deeply revealing moment. Dexter later tells him it’s okay to feel anger—the key is not acting on it.

This is where the show hits some emotional gold. Dexter’s trying. Really trying. And Harrison, despite his bloodline, is trying too. Their efforts to be better are clumsy, sometimes hypocritical, but wholly human.

The Death of Lady Vengeance, and the Rise of Real Stakes

As the detectives arrive to question Mia, the jail erupts in chaos. An alarm. A hanging. A dead woman. And a guard suspiciously similar to the gambler Charley paid off.

Lady Vengeance is gone. Silenced. Murdered. Or suicided. Either way, the message is clear: Prater plays for keeps, and his reach is vast.

Dexter hears the news on the radio as he drives to his next unholy appointment. He clutches the wheel. So do we.

Final Thoughts: The Twist That Finally Justified This Revival

For a show that once stumbled so hard it poisoned its legacy (cough season 8 cough), Dexter: Resurrection continues to surprise by not only cleaning up its mess but constructing something legitimately compelling in its place.

Episode 6 takes the tried-and-true Dexter formula and tosses in a twist so simple and so earned that it feels like vintage Showtime. The Gemini Killer being twins? It’s not just clever—it’s structurally satisfying. It retroactively makes the earlier episodes feel more meticulous.

Add in Michael C. Hall’s subtle performance, Harrison’s coming-of-psyche journey, and the increasingly fascinating Leon Prater, and you’ve got one of the best episodes in the revival so far.
