Egg Aegon Targaryen has officially stepped out of the shadows, and his true identity is already reshaping how fans view the growing world of Game of Thrones spin-offs. With A Knight of the Seven Kingdoms reaching a major turning point in Episode 3, viewers finally learn that the quick-witted squire known as Egg is not a common boy at all, but a prince of House Targaryen.
This revelation not only changes the story of Ser Duncan the Tall, but also firmly connects the series to House of the Dragon and Game of Thrones. Many viewers are now asking the same question: How is Egg Aegon Targaryen related to Rhaenyra Targaryen and Daenerys Targaryen?
The answer lies deep within the Targaryen family tree.
The Big Reveal in A Knight of the Seven Kingdoms
The third episode of A Knight of the Seven Kingdoms, appropriately titled “The Squire,” delivers one of the most important twists of the series so far. During a violent confrontation between Ser Duncan the Tall and Prince Aerion Targaryen, Egg steps forward to stop the brutality.
What makes the moment shocking is not just Egg’s bravery, but the reaction of the Kingsguard and Prince Aerion himself. They listen. They obey.
That is when the truth becomes clear: Egg holds authority because he is Aegon Targaryen, youngest son of Prince Maekar Targaryen and grandson of King Daeron II.
For readers of George R. R. Martin’s Dunk and Egg novellas, this twist was expected. For new viewers, it reframes every earlier interaction Egg has had since the series began.
Who Is Egg Aegon Targaryen?
Egg Aegon Targaryen is not just any royal child. He is a boy who deliberately chose to live among the smallfolk, shaving his head and hiding his silver hair to avoid recognition. His decision to travel with Dunk is not driven by privilege, but curiosity, humility, and a desire to understand the real world.
Unlike his cruel older brother Aerion, Egg shows empathy, intelligence, and moral courage. These traits may seem small now, but they matter greatly when placed into the wider history of Westeros.
Egg’s story is not just about survival—it is about the shaping of a future king.
Egg Aegon Targaryen’s Place in the Timeline
One of the most important things to understand about Egg Aegon Targaryen is when his story takes place.
- House of the Dragon is set during the Targaryen civil war known as the Dance of the Dragons.
- A Knight of the Seven Kingdoms takes place around 78 years later.
- Game of Thrones occurs about 89 years after Egg’s adventures.
By Egg’s time, dragons are gone, the Targaryens are weaker, and their power rests more on politics than fear.
This historical distance explains why dragons are absent in A Knight of the Seven Kingdoms, while also making Egg a key bridge between eras.
How Egg Aegon Targaryen Is Related to Rhaenyra Targaryen
Egg Aegon Targaryen is five generations removed from Rhaenyra Targaryen, the central figure of House of the Dragon.
Here is the simplified lineage:
- Rhaenyra Targaryen
- Her son Viserys II
- His son Aegon IV
- His son Daeron II
- His son Maekar I
- His youngest son: Aegon “Egg” Targaryen
This makes Rhaenyra Egg’s great-great-great grandmother.
Although Rhaenyra never appears in A Knight of the Seven Kingdoms, the consequences of her war are everywhere. The loss of dragons, the weakening of the crown, and the internal fractures within House Targaryen all trace back to her era.
Egg lives in the aftermath of her legacy.
How Egg Aegon Targaryen Is Related to Daenerys Targaryen
Egg Aegon Targaryen is even more closely related to Daenerys Targaryen, one of the most iconic characters in Game of Thrones.
In fact, Egg is Daenerys’s great-grandfather.
The family line continues as follows:
- Egg Aegon Targaryen
- His son Jaehaerys II
- His son Aerys II, the Mad King
- His children Daenerys and Viserys
This connection makes Egg a direct ancestor of the Mother of Dragons. While Daenerys grows up in exile, Egg spends his youth hiding in plain sight. Their paths could not be more different, yet both are shaped by the same fractured dynasty.
Egg’s Connection to Jon Snow
Because of his link to Daenerys, Egg Aegon Targaryen is also connected to Jon Snow.
Jon is the son of Rhaegar Targaryen, who was Daenerys’s brother. That makes Egg Rhaegar’s great-grandfather and Jon Snow’s great-great-grandfather.
This means that the quiet boy walking beside Dunk is part of the same bloodline that eventually produces:
- The Mad King
- The Mother of Dragons
- The King in the North
Few characters sit at such an important crossroads of Westerosi history.
The Clues That Revealed Egg’s True Identity
Long before the official reveal, A Knight of the Seven Kingdoms quietly planted hints about Egg’s identity.
The Targaryen Coin
In the first episode, Dunk encounters a man carrying a coin marked with the three-headed dragon. This moment subtly signals a nearby royal presence.
Egg’s Shaved Head
Like other Valyrian-descended characters in the franchise, Egg hides his silver hair to avoid attention. This visual choice mirrors tactics seen in House of the Dragon.
His Reaction to Aerion
Egg’s emotional outburst during Aerion’s joust goes far beyond what would be expected from a common squire. His anger reveals a personal, familial wound.
Together, these clues reward attentive viewers and deepen the rewatch value of the series.
Why Egg Aegon Targaryen Matters
Egg Aegon Targaryen is not just a trivia connection between shows. He represents a rare perspective in the Game of Thrones universe: a Targaryen who truly understands the cost of power.
His journey from anonymous squire to future king shows how leadership is learned, not inherited. By placing Egg at the center of this story, HBO grounds its fantasy in humanity, struggle, and moral growth.
As A Knight of the Seven Kingdoms continues, Egg’s choices will echo forward in time—right up to the fall of the Iron Throne itself.
