Considering my favorite characters have been Arya, Theon, Melisandre, Beric and Oberyn, I'm satisfied. ?
I always loved that there was a war going on and the BWB never gave a shit. They were just out hunting Lannisters because Ned sent them on a mission in book 1. It's like those Japanese soldiers who never realized WWII ended.
I am disappointed that White Harbour and the Crannongmen never played a role. I'd have liked to see Victarion too.
