Ok, now we’re talking! From the same Twitter source comes word of another role leaked onto Spotlight. This time it is actress Gemma Whelan who is listed as playing the role of Yara Greyjoy. Now there is no Greyjoy named Yara in the books. But according to this post over at Westeros, a casting breakdown was sent out for a character to play Theon’s sister and her name was reportedly Yara Greyjoy. So unless they have invented a new sister for Theon, it would seem Asha has been cast and had her name changed (probably to avoid confusion with Osha).
Winter Is Coming: Another actor that fits the profile, young, just out of drama school, solid representation, etc. Obviously we will wait for official confirmation before listing it as a done deal, but it seems promising. She looks younger than I thought they would go for Asha. But I’m sure she is talented.
