This Sunday's episode, "The Climb," marked the end of the line for Ros. In an interview with HBO.com, actress Esmé Bianco discusses the evolution of her character, why she spied for Varys, and what's so appealing about life in King's Landing.
Ros managed to gain the confidence of both Varys and Littlefinger. What is about her that made them trust her?
Everyone thinks she has lower expectations. I think people underestimate her because she's not someone who's trying to marry the king or steal the throne. She's on a different level. But she is so clever at being a woman. She knows how to use her feminine wiles to gain trust, so people have that confidence in her, but they're underestimating how ambitious she is.
