Egg’s Secret in Westeros: Who He Really Is (Spoiler-Light)

Updated: January 27, 2026

If you’ve started A Knight of the Seven Kingdoms and immediately wondered, “Okay… who is this kid, and why does he feel way too bold to be a random stable boy?”— you’re not alone. The show plays it coy early on, but the answer is a fun piece of Westerosi history.

This guide keeps things spoiler-light: it explains Egg’s identity and why it matters, without digging into later major plot turns.

Quick Answer: Who Is “Egg”?

“Egg” is Aegon Targaryen—a young Targaryen prince traveling incognito who becomes the squire of Ser Duncan “Dunk” the Tall. In the wider history of Westeros, he’s known as King Aegon V Targaryen (often nicknamed Aegon the Unlikely).

In the show, Egg is played by Dexter Sol Ansell, and the series centers on his partnership with Dunk as they wander Westeros far from court politics.

A Trailer-Quick Refresh (No Plot Breakdown)

If you want a vibe check for the show’s tone—mud, tourneys, underdogs, and the odd moment of danger—here’s the official final trailer:

How the Show Introduces Egg (And Why Viewers Get Suspicious)

Early on, Egg reads like a street-smart, sharp-tongued kid who talks his way into Dunk’s orbit—and then refuses to leave. Even without deep lore knowledge, the show drops subtle “this kid is not what he says he is” signals:

He’s unusually confident around knights and nobles for a supposed nobody.
He’s stubborn about becoming a squire, as if he believes it’s his right, not a favor.
He’s hiding something (and not very patiently).

If you’ve watched enough Westeros stories, you learn to treat “mysterious orphan” claims as… flexible.

Identity Explained: Why “Egg” Is Actually Aegon Targaryen

Egg’s “stable boy” presentation is a cover. In George R. R. Martin’s original Dunk & Egg story (The Hedge Knight), Egg is a young prince who has deliberately shaved his head to help hide his Valyrian look and move through the world unnoticed.

The point isn’t just “secret royal” drama. Egg is testing real life—the kind that happens far from castles: hunger, bad roads, bad innkeepers, petty lords, and the everyday risks that highborn people usually outsource to other bodies.

That “walking the long way” energy is basically the whole Dunk-and-Egg formula: one towering would-be knight with a big heart, and one tiny “helper” who is… absolutely not a normal helper.

Why It Matters (Without Spoiling Future Arcs)

Egg’s true identity matters because it changes the stakes of everything around Dunk. When you realize the kid is royal, every small choice—where they sleep, who they trust, who they offend—gets sharper.

It also reframes Dunk as more than a wandering underdog: he’s becoming a key influence on someone who will eventually have power in the realm’s history. The relationship is the engine of the story: it’s mentorship, friendship, and a constant push-pull between “be a good man” and “be a prince.”

Reddit’s Take: Why the Nickname “Egg” Stuck

One of the most common questions fans kick around is whether “Egg” is just a cute nickname because his name is Aegon (sounds like “egg-on”) or if it comes from his shaved head disguise.

Why do so many people call Aegon's "Egg"?

The fun part: both ideas can coexist in fan conversation. In-story, the shaved head is the “visible” reason the nickname lands quickly. Out-of-story, the wordplay makes it sticky forever.

What Reddit Theories Say About Egg’s Identity (Spoiler-Light)

Across Westeros subreddits, the “Egg reveal” tends to split into two camps: people who know the books and immediately clock him, and show-only viewers who feel the twist coming but can’t name it yet.

Who's your favorite Aegon and why ?

Either way, most fans agree on one thing: “Egg” is an all-time great Westeros nickname—because it sounds goofy until you realize it belongs to someone who’s quietly important.

How Egg Connects to the Bigger Game of Thrones Timeline

A Knight of the Seven Kingdoms sits in a sweet spot: it’s set long before Game of Thrones, but after the era explored in House of the Dragon. The Targaryens still hold the Iron Throne, but the world feels more grounded: fewer “end of the world” prophecies, more “can we afford dinner?”

That makes Egg a perfect bridge character—someone with royal blood who’s learning firsthand what the realm is actually like when you’re not looking down from a balcony.

Clues to Watch For (If You Like Picking Up Hints)

How he talks about “knighthood”: it’s less starry-eyed and more personal—like it’s something he’s owed.
How quickly he understands status games: he’s small, but he’s not socially naive.
What he avoids saying about family: when characters dodge details in Westeros, it’s usually on purpose.

The show does a nice job making Egg feel like a real kid first—and a “reveal” second.

FAQ

Is Egg a Targaryen in the show?

Yes. “Egg” is Aegon Targaryen traveling under a nickname while he squires for Dunk.

Is Egg the same Aegon as in other Game of Thrones stories?

He’s a different Aegon than any modern-era plotlines you might be thinking of. Westeros has a lot of Aegons—this one is a historical figure in the Targaryen line who becomes King Aegon V.

No. The show is designed so that newcomers can enjoy the buddy-adventure vibe, while book readers get the extra layer of dramatic irony.

What’s the simplest way to describe the Dunk & Egg story?

A wandering hedge knight tries to be honorable in a world that often punishes it—while mentoring a “kid” who is secretly one of the most important boys in Westerosi history.
