Warning: Spoilers ahead for "House of the Dragon" season three, episode three, and for the book "Fire & Blood."The elusive Daeron Targaryen is finally joining the fray in "House of the Dragon."Daeron is the youngest son of Alicent Hightower and the late King Viserys Targaryen — their fourthborn child after Aegon, Helaena, and Aemond. Like his siblings, Daeron is a dragonrider, bonded to a young blue dragon named Tessarion.Unlike his siblings, however, Daeron left King's Landing as an infant. He was sent as a ward to Oldtown, the seat of House Hightower, and is scarcely known to the royal family. Throughout the first two seasons of the HBO show, Daeron is kept far away from the action.In "House of the Dragon" season two, Daeron is mentioned as both a potential threat to his half-sister, Queen Rhaenyra Targaryen, and a promising pawn in Aegon's army — especially once Tessarion has grown big enough to fly into battle. Daeron is also mentioned in a conversation between his mother and uncle, Ser Gwayne Hightower (Freddie Fox), who was also raised in Oldtown.Gwayne tells Alicent that 16-year-old Daeron is hardworking, clever, and kind, setting him apart from his cruel, bloodthirsty brothers.In season three, Daeron finally makes his onscreen debut, marching with the Hightower army and taking orders from his mother's cousin, Lord Ormund Hightower (James Norton) — that is, until episode three, when their campaign is interrupted by Daemon Targaryen (Matt Smith). Now that Rhaenyra has ascended the Iron Throne, the king consort plans to take Daeron hostage as part of the Hightowers' surrender terms.
