Totally agree I like what they're doing with Tywin. He a typical Martin character not good or evil - just capable of both, I think he would know Arya is a highborn, In the books when Theon is adapting to his new persona he has to take care to say "m'lord"instead of "my lord" to keep from giving away his noble birth. The character they're doing the worst with has to be Baelish. On the show he seems obvious and not especially clever. In the book he is a total enigma, you can never be sure what his motivations or loyalties are. He just seems to thrive in the chaos. Gillen is doing the best he can with the material but still disappointing.
