House of the Dragon viewers have been left on the edge of their seats over the last 10 weeks by the violent family war, political scheming and of course those fire-breathing monsters. But two characters that have caused much intrigue confusion are two twin brothers, who are played by a real set of identical twins, Luke and Elliott Tittensor.
Ser Arryk and Ser Erryk Cargyll are two sworn knights of the Kingsguard, who got their first real taste of on-screen action in the Game of Thrones spin-off during epiosde 9 when they 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 plotlines 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.
