But wait, there’s more! With the Game of Thrones season 2 cast, you also get Theon Greyjoy’s bold sister Asha (except we’re not going to call her that).
Producers have tapped Gemma Whelan (Gulliver’s Travels, The Wolfman) to play
Asha Yara Greyjoy, the older sister of the Stark family’s impulsive young ward, Theon. Yara defies the Ironborn traditions of her family by commanding her own ship and leading men into battle, as well as having a penchant for axes.
Producers changed the character’s name from Asha to Yara presumably because the former sounds too much like another character in the show, Osha. (They did the same with young Lord Robert in the Eyrie in season 1, changing his name to Robin as not to confuse him with King Robert Baratheon). For those who missed the rest of the season 2 cast, here’s who will play Stannis and Melisandre and Davos; here’s who’s cast for Brienne and here’s Margaery Tyrell.
