Since he rescued her during the attack, Granny seems to be attached to Sashok. He’s the “default leader” of the Moat Rebellion Nomads. When Kolyan is raised as a zombie, Sashok sprints across the camp to make a beeline to him and does the most damage. He was very good friends with Kolyan, and it is a religious affront and a terrible pain to see someone raised as a zombie who didn’t enter in a pact to do so. And to be raised by an enemy and turned on your own people is the worst of all. After Sashok destroys Kolyan’s body, he vomits and cries while Sina comforts him.
