Ty, 20, looks seriously different in the first-look at episode six, and is wearing a white blonde wig. He plays the eldest son of Viserys Targaryen and Alicent Hightower, Aegon Targaryen, who fans of the show will know has a claim to the Iron Throne as the eldest male heir to King Viserys – despite his older sister Rhaenyra being officially declared the heir to the Iron Throne.

Please say we get a scene between and Matt Smith," while another person added: "I’m sorry, I just think it’s so funny that Ty Tennant (the son of David Tennant) is going to be in House of the Dragon with Matt Smith… the son of the Tenth Doctor with the Eleventh Doctor?!?"

Speaking of the cast change, one person wrote: "#MillyAlcock is the standout. I can’t believe we only get her for one more episode? I wish she could play #Rhaenyra the entire series. I don’t know much about Emma D’Arcy but I’m not ready for the cast change." Another person added: "I went into this show knowing I'd love daemon but ever since episode one Milly Alcock has been carrying the show, I'm very worried my opinion of the show will change when the cast changes."
