Who could have imagined things escalating so quickly between Dexter and Gareth?
We’re already seven episodes into Dexter: Resurrection, and with episode 8 arriving later this week, fans are asking the same burning question: where is this season heading, and how will it end?
So far, Dexter Morgan has proven to be just as sharp, resourceful, and deadly as he was in the early seasons of the original series. But despite his strength and intelligence, this new chapter has introduced elements from his past that could signal his downfall.
Throughout the season, Dexter crossed paths with some of the deadliest killers imaginable—many of whom he met at Leon Prater’s infamous dinner party for serial killers. Among them were Lowell, “The Tattoo Collector”, Mia, “Lady Vengeance”, Al Jolly, aka Rapunzel and Gareth, “The Gemini Killer”.
Each of them had left a trail of bodies behind, forcing Dexter to do what he does best—feed his Dark Passenger and take them out before they could cause more destruction. By the end of episode 7, most of them had been eliminated, leaving only Al Jolly still standing.
But it wasn’t Dexter’s methodical kills that caused the most buzz this week—it was an unexpected, emergency kill that happened right in front of Prater, Charley, and Al. This shocking moment left fans divided and questioning the writers’ intentions.
The Gemini Killer’s Twin Twist
Episode 6 delivered what many fans consider one of the most shocking twists in the Dexter franchise: the reveal that the Gemini Killer wasn’t just one man, but two identical twin brothers—both named Gareth.
This revelation explained how the FBI’s most wanted killer was so successful at evading capture. With a secret twin acting as both an accomplice and an alibi, Gareth was nearly untouchable. Since the world never knew he had a brother, suspicions never fell on him.
Naturally, fans expected this to set up a major storyline. The logic was clear: if Dexter killed one Gareth, the surviving twin would become a far more dangerous adversary, fueled by revenge.
But the writers had other plans.
How Dexter Killed Two Notorious Serial Killers in Less Than 24 Hours
Episode 7 shocked viewers again when Dexter confronted the second Gareth twin. Sitting calmly on a garden bench at Prater’s mansion, Gareth denied having a brother—until Dexter taunted him by revealing he had killed Gareth #1 the night before.
Normally, Dexter only reveals such truths in the kill room, when escape is impossible. Here, however, he baited Gareth into attacking him with a broken glass. When Gareth lunged, Dexter swiftly overpowered and killed him. To everyone watching, it looked like self-defense.
And just like that, the Gemini Killer subplot ended almost as quickly as it began.
Why Did the Writers End the Gareth Twins So Quickly?
Fans were stunned that what seemed like a season-defining adversary was eliminated so fast. But there are a few in-story explanations for why Dexter acted so decisively:
1. Gareth Suspected Dexter
Since Dexter’s arrival, everything began to unravel for the group. Gareth already suspected “Red” (Dexter) of being behind Lowell’s disappearance and Mia’s downfall. Killing Gareth before he could expose him was a calculated move.
2. Covering His Tracks
By staging the fight as if Gareth attacked first, Dexter shifted suspicion away from himself. To Prater and Charley, it looked like Gareth had turned on the group, and being responsible for what happened to Lowell and Mia.
3. Learning From Past Mistakes
Dexter knows the cost of underestimating enemies—most notably Arthur Mitchell, the Trinity Killer, who he let live too long. Gareth was a meticulous killer who even the FBI couldn’t pin down. With nothing to gain from keeping him alive and everything to lose, Dexter struck quickly to protect Harrison and prevent another Rita-like tragedy.
Fan Reactions: Shock, Confusion, and Controversy
The decision to introduce a twin twist in episode 6, only to resolve it within the first half of episode 7, has left many fans conflicted.
Some feel the storyline was wasted, as the surviving Gareth could have been an incredible long-term villain for Dexter. Others argue the subversion was intentional—that by killing both twins so quickly, the writers proved that Dexter: Resurrection isn’t afraid to break expectations and keep the audience guessing.
Final Thoughts
Episode 7 of Dexter: Resurrection proved one thing: this revival series refuses to be predictable. While fans expected Gareth #2 to become a major threat, Dexter eliminated him in a bold, shocking move that left audiences stunned.
