Warden of the North
Ned Stark's head
You have it right. They took the body from the house to the barn in the truck, and later Madison went and chopped the head off to give to Walker as part of her deal.
What I cant figure out why bother putting in the barn? Why not bury it? Unless the boys are in on the deal and they want to prevent the rest of the people at the ranch from knowing whats actually happening?
Anyways, have to think the next arc will involve walkers taking down the ranch. They were pretty much a non-factor for the first half.
Maybe they'll make the ranch and the reservation team up to stop a herd.
