According to Entertainment Weekly, which first reported the news, the name change was made so viewers could avoid confusion with another character, the similar-sounding Osha — though we're pretty sure it's not that hard to make the distinction.Whelan is the latest to join an ever-growing guest cast for Season 2. Two weeks ago, Liam Cunningham signed on to play Davos Seaworth, along with Stephen Dillane as Stannis and Carice van Houten as Melisandre.
