Looks like they cast Ramsay Snow/Bolton. I think he looks like he can pull that part off, plus he has some real actor chops which is good because he needs to nail this role. There is talk of him filming already, so i guess they are going to show the Theon/Ramsay arc at least some this season which i am really happy about. There is a lot of potential for excellent scenes between Ramsay and Theon that were never shown in the books.
