Speaking exclusively to SciFiNow at a press event for the Game Of Thrones Season 2 Blu-ray and DVD, Richard Madden, who plays the forthright King in the North Robb Stark, and Michelle Fairley, iron matriarch Catelyn Stark, tease a change in the already strained relationship between the mother and son in Game Of Thrones Season 3…

“For Season 3 you’re thrust into a different dynamic – we meet a bunch of new characters in Season 2 that change the way we interact with each other as characters,” teases Madden, “and how those characters interact with other people. Which is just about as specific as I can get.”

At the end of Game Of Thrones Season 2, Robb Stark tied the knot with Talisa Maegyr (Oona Chaplin) against Catelyn’s wishes – she’d previous betrothed the Young Wolf to one of the many daughters of lecherous Walder Frey (David Bradley) in exchange for his support for their war on the Lannisters.

Coupled with Catelyn undermining Robb’s authority by releasing their sneering hostage Jaime Lannister (Nikolaj Coster-Waldau) in the hope his family release the Stark daughters she believes are being held in King’s Landing (one isn’t, but she doesn’t know that) in return, there’s definitely some tension there that will conspire to splinter the mother and son dynamic even further apart.

“That is an angle you can take!” says Fairley of Catelyn’s betrayal. “Yes, of course, but she is doing ultimately – or she is convinced – for a very valid and good reason, which is to get the return of her daughters and hopefully end this stupid war. In her naivety – and it goes back to the earlier question about the women [of Game Of Thrones], once they take that knock they know never to go down that alley again, you learn from your mistakes – and she gets her comeuppance.”

“I potentially have to accept a new family,” expands Fairley. “Catelyn spends a lot of time on her own in Season 3, so that’s a lot of reflection – being honest and possibly admitting to her own involvement in the demise of her family.”
