The acclaimed actor who joined the cast as Gareth, shared fascinating insights about his role.
Dexter Morgan returns this Friday with a brand-new episode of Dexter: Resurrection, and it’s shaping up to be one of the most pivotal yet. Episode 4 brings a dramatic shift in the story, as five high-profile new characters are introduced, all during an ominous dinner party hosted at Leon Prater’s mansion.
Fans have been eagerly anticipating this scene since it was subtly teased in earlier episodes. The buildup has been particularly strong since Episode 3, "Backseat Driver," and even more so following in the promo for Episode 4, "Call Me Red," which offered glimpses of Dexter arriving at the gathering while disguised as Red.
This kind of twisted social situation is exactly the type of challenge that ignites Dexter’s curiosity. And this time, he’s stepping into a room full of people like him — or worse. Among them is Gareth, better known as The Gemini Killer, a character already making waves within the fandom.
Actor David Dastmalchian, who brings Gareth to life, recently spoke with Mashable about what makes this new serial killer so unique within the Dexter universe. While Dastmalchian is no stranger to dark and complex roles — from 12 Monkeys to portraying Albert DeSalvo in Boston Strangler, he says Gareth has been the most fun he’s ever had playing a killer.
Gareth’s moniker, The Gemini Killer, as Dastmalchian hints, ties directly into his character’s twisted duality. Gareth doesn’t just kill — he does so in specific, brutal ways that sometimes involve multiple victims at once. His methods are gruesome, calculated, and deeply symbolic.
But what really sets Gareth apart from past villains in the Dexter franchise is what Dastmalchian calls his “secret power”. It will make life “very challenging” for Dexter Morgan he said, something no previous antagonist has ever brought to the table. Gareth is not just another psychopath in Dexter’s path; he’s the FBI’s most wanted murderer, and he has an ability that could change everything for Dexter Morgan.
While the actor stopped short of revealing the full nature of Gareth’s power, he teased that once viewers realize what's really happening, it may blow their minds. There's clearly more to Gareth than meets the eye — and his presence could push Dexter into unfamiliar territory, where being diplomatic might be the only way to survive.
