This really is a missing scene from the book. The structure is excellent and I love the way you've captured the personalities and voices, and that you've centered it around someone who is so vital to the whole series yet is seen mostly through other peoples' eyes. Also the wolf/hound thread.
Thanks so much! Structure is one of my joys, so I'm glad you noticed it. And it was funny to me to realize (after Piscaria's comment) that Esca wasn't actually in the story, because it's "about" him.
