Chief among them is the prequel House of the Dragon, which is currently deep into its third season on the air. Fans are tasked with remembering which dragon belongs to who, and while some book readers are mad about the character Nettles being cut, I would still fight for Sheepstealer. House of the Dragon Season 3 has featured a number of deviations from the source material, which is fairly common for book-to-screen adaptations. Chief among them is Rhaena claiming Sheepstealer, and the show cutting the character Nettles entirely. He's been living alone with his very first rider, Rhaena, and then got beaten up and left for dead.
