I'm glad to see I was right that Arya was playing Littlefinger, and not the other way around. I'm a little surprised that Bran and Sam pooled their knowledge this quickly (or that Sam even realized he had his part of the puzzle). I'm also a little surprised that the rift between Cersei and Jamie happened this soon. But I'm not surprised that Cersei being sane was just a ruse. Things are really moving fast!
