A Knight of the Seven Kingdoms Episode 3 Ending Explained: Who Is Egg?

The ending of A Knight of the Seven Kingdoms Episode 3 delivers a major reveal that reshapes the story in a significant way. While the episode itself provides enough clues for careful viewers, the final moments confirm what the show has been strongly hinting at since the beginning. For anyone searching for clarity around a knight of the seven kingdoms episode 3, especially the identity of Egg, the answer is finally made explicit.

The Game-Changing Reveal in Episode 3

In a knight of the seven kingdoms episode 3, the story reaches its turning point during the tournament at Ashford. Ser Duncan the Tall attacks Prince Aerion Targaryen after Aerion assaults the puppeteer Tanselle Too-Tall. As Aerion prepares to retaliate violently, Egg unexpectedly intervenes.

Despite Dunk’s warning to stay silent, Egg commands the guards to release him—and they obey. When Aerion mocks Egg’s appearance, asking about his missing hair, Egg responds that he cut it off so he would not look like his brother. In that moment, the truth becomes undeniable: Egg is no ordinary squire.

Who Is Egg in A Knight of the Seven Kingdoms Episode 3?

The ending of a knight of the seven kingdoms episode 3 confirms that Egg is actually Aegon Targaryen. Throughout the episode, several clues point in this direction. Egg repeatedly avoids the Targaryens at Ashford, Maekar’s missing son is mentioned without using the name “Aegon,” and Egg’s shaved head conceals his distinctive Targaryen hair.

Egg had shaved his head to hide his identity while traveling. He and his brother Daeron were meant to arrive at Ashford ahead of the rest of the royal party, but instead ended up at an inn where Egg met Dunk. Despite being on the run, Egg chose to return to Ashford to squire for Duncan, showing his clear discomfort with his royal status and his deep resentment toward his brother Aerion.

The Targaryen Family Context

As explained through a knight of the seven kingdoms episode 3, Maekar Targaryen has several sons: Daeron, Aerion, Aemon, and Aegon. While Aemon has not yet appeared in the series, Aegon’s reveal recontextualises much of Egg’s behaviour, including his detailed knowledge of knights and history and his struggles with basic squire tasks.

This revelation does not end the partnership between Dunk and Egg. Instead, it confirms that their journey together is far from over, even with the knowledge that Dunk’s squire is actually a prince of the realm.
