SPOILER ALERT: Episode 3 of 'A Knight of the Seven Kingdoms' just dropped the biggest reveal since Jon Snow's parentage—and it changes everything.

Dexter Sol Ansell, the 11-year-old sensation who stole scenes as young President Snow, is now breathing fire as Westeros' most unexpected royal. In an exclusive with TheEntBase, Ansell breaks the internet by confirming what book fans have known for years: "Egg" isn't just a nickname—it's short for Aegon V Targaryen, future king of the Seven Kingdoms.

"I feel like a dragon ready to take flight," Ansell gushed, his excitement palpable. "My family went absolutely mental when they found out. They were screaming, 'You're a Targaryen?!' while I was just trying to remember my lines with a gummy worm stuck in my cheek."

The reveal comes in the explosive finale of "The Squire," when Dunk (Peter Claffey) faces execution after defending a puppet show from Prince Aerion's brutality. In a moment of pure cinematic magic, the small, bald squire sheds his disguise and declares: "I am Prince Aegon, son of Maekar, brother to Aerion." Cue dragon-sized gasps across the realm.

What makes this twist even juicier? Ansell admits he's never watched 'Game of Thrones.' "I'm living the Targaryen life without knowing the baggage," he laughed. "But my castmates schooled me—apparently, being a Targaryen means you either rule the world or burn it down. No pressure."

Behind the scenes, director Sarah Adina Smith kept the young actor fueled with sour gummy worms during the pivotal scene. "She'd hand me a worm, yell 'Action!', and suddenly there's explosions and crowds rushing everywhere," Ansell recalled. "I'm standing there thinking, 'Do I chew or deliver my lines?' Turns out, you can do both."

This isn't just a reveal—it's the ignition of a dynasty. Aegon V Targaryen, known as "Aegon the Unlikely," becomes one of Westeros' most consequential kings, whose reign sets the stage for the events of 'Game of Thrones.' And Ansell is ready to wear the crown. "We're already filming 'The Sworn Sword,' and let's just say... the dragon has only just awakened."

With three Dunk & Egg tales planned and more from George R.R. Martin's outlines, this reveal marks the beginning of a saga that could rival the original series. As Ansell puts it: "Buckle up, because this egg is about to hatch into a fire-breathing, throne-taking phenomenon."
