Once, doubting the reality of totems, Sam hadn’t been. He had thought that totems were merely psychological constructs through which a shaman organized his thoughts for magic, that they had no independent existence. He still wasn’t completely convinced that totems were thinking entities in their own right, but he could no longer deny all evidence of that. Thus, he had accepted the necessity of dealing with the being sitting before him as though Dog were an independent entity. "Yes, I’m sure."
