"I think in many ways, some of the stuff [Sansa] does in later episodes are every bit as heroic as things that Arya does. She just has to play a different game than Arya."

"[Catelyn]’s not a coward, she’s actually somebody who’s got all those qualities inside her but she’s never had to utilise them in that way until she’s on the way back from King’s Landing and suddenly Tyrion Lannister walks into the bar. So she’s acting on instinct there. She has sense of right and wrong, she has a moral compass and she wants that man to pay for what he has done to her son. Little does she know what she’s opening up at that point. That catapults her on a different trajectory and then she keeps going. Then she loses her husband; I think all of these different things which happen to her just add to her strength.

With Ned’s death, I think at that point — which I find very interesting — is they don’t have the big emotional breakdown scene which you would expect because basically she can’t indulge that, she has to keep going or I think she would collapse and she can’t because she has children to think of. It’s almost like the grief that she has for Ned is the energy she requires to keep going, to propel her forward to get revenge actually."
