This. I really liked the scene a few eps back when she arrested Tyrion but this last scene was just head and shoulders!Her acting that entire scene was just sublime.
This is one of the only shows I have seen that challenges the invincibility of key characters. And the way they play with the idea of survival, like having Robb rise up again and Catelyn crawling under the tables, it kind of lingers, the "well just maybe something will happen and they will be fine" feeling. Fantastic.
