In a revealing interview with Entertainment Weekly, published on January 29, 2026, of HBO’s A Knight of the Seven Kingdoms, actor Finn Bennett opens up about his portrayal of Prince Aerion Targaryen. Bennett, a 27-year-old British actor, best known for his role as Officer Peter Prior in True Detective: Night Country, steps into the Westerosi world of George R.R. Martin’s Dunk and Egg novels. The interview delves into the psyche of Aerion “Brightflame,” a Targaryen prince whose vanity and cruelty have quickly made him a fan-favourite villain to hate.
As the series is adapted from the book, The Hedge Knight, Aerion’s chaotic presence at the Ashford tourney sparked intense online reactions. And Bennett’s insights provided a glimpse into how he humanized a character described in the books as having “no redeeming qualities.”
At the heart of Bennett’s approach is the philosophy that “monsters aren’t born, they’re made.” He emphasizes this in the EW piece, explaining that while Aerion Targaryen appears all bad on paper, he sought deeper motivations to make the role playable.
This mindset aligns with the broader themes of Martin’s universe, where Targaryen “madness” often stems from the pressures of dynasty, power, and legacy. In Aerion’s case, Bennett portrays him as a product of a fracturing House Targaryen. A dynasty where the family’s grip on power is slipping, leading to overcompensation through brutality.

In Episode 3, Aerion Targaryen’s monstrous side is on full display. He arrives at the tourney in dramatic fashion, clad in black armor with flame motifs, and quickly escalates tensions. His later assault on puppeteer Tanselle, snapping her fingers over a perceived insult to dragons exemplifies his sadism, drawing comparisons to infamous GOT villains like Joffrey Baratheon.
Social media buzz, including memes about Aerion’s “heated rivalry” with a Kingsguard knight represents how Bennett’s nuanced acting makes the cruelty feel earned rather than caricatured.
“They don’t have the firm grasp on power that they (Targaryens) used to have,” he notes, tying Aerion’s actions to embarrassment over the family’s perceived weakness. This “made monster” angle adds layers: Aerion Targaryen isn’t just evil for evil’s sake; it represents his way of lashing out to restore dominance, making his downfall (hinted at in the books) all the more satisfying.
The interview also touches on practical challenges, like the custom helmet based on a 3D scan of Bennett’s face, which he jokingly called ugly after modifications. His stunt double handled blind riding scenes due to the visor’s impracticality, highlighting the unavoidable problems embodying this menacing figure.
Bennett also says that he avoids reviews to dodge negativity but learns of fan reactions through his family, reacting with delight to the memes.
Ultimately, Bennett’s “monsters aren’t born” ethos elevates Aerion from a one-note antagonist to a tragic product of his environment, enriching the show’s exploration of power and madness.
