In the Season 1 finale of 'A Knight of the Seven Kingdoms,' viewers are introduced to Egg, a young boy who becomes the squire of Dunk, the hedge knight. Egg is revealed to be a Targaryen prince, the son of Maekar Targaryen, and the younger brother of Baelor, who dies during the trial of the seven. His full name is not given in the series, but in George R.R. Martin's novellas, he is Aegon Targaryen, who later becomes King Aegon V.
After Baelor's funeral, Maekar asks Dunk to take Egg as his squire, but Dunk initially refuses, saying he is done with princes. However, after a visit from the ghost of his mentor Ser Arlan of Pennytree, Dunk reconsiders and decides to take Egg away from his Targaryen family. Against Maekar's wishes, Dunk and Egg ride off together as knight and squire.
The finale hints at future adventures, with Dunk and Egg discussing a journey to Dorne. Showrunner Ira Parker confirmed that Season 2 will follow the second novella 'The Sworn Sword,' which takes place in Dorne. The final scene shows Maekar searching for Egg, suggesting possible Targaryen crossovers in future episodes.
