House of the Dragon fans have left on the edge of their seats over the last ten weeks - but two characters in particular who have left viewers scratching their heads.
Twin brothers, who are played by a real set of identical twins, Luke and Elliott Tittensor, got their first real taste of on-screen action in the Game of Thrones spin-off during episode 9 as Ser Arryk and Ser Erryk Cargyll - two sworn knights of the Kingsguard.
The pair began searching for King Aegon II Targaryen on the orders of Ser Otto Hightower. In what's set to become one of the most tragic plots of the entire show, the twins have taken different sides in the war, with Arryk staying with the Greens and Erryk leaving to join Queen Rhaenyra and the Blacks.
