and his letter to the Greyjoys from before:

"Balon Greyjoy, Lord of the Iron Islands and invader of the North. I give you until the full moon to order all ironborn scum out of the North and back to those sh*t-stained rocks you call a home. On the first night of the full moon, I will hunt down every islander still in our lands and flay them living the way I flayed the 20 ironborn scum I found at Winterfell. In the box you'll find a special gift: Theon's favorite toy. He cried when I took it away from him. Leave the North now or more boxes will follow with more Theon. Signed Ramsay Snow, natural-born son of Roose Bolton, Lord of the Dreadfort and Warden of the North."
