Sheriff B. Knox is the sheriff of Steveston, Oregon. Although he had been taken as a host by an immature cloned symbiote and had become a nightwalker, he continued to perform his duties as sheriff during the day, and he cooperated fully with SG-1's investigation into the disappearance of Dr. Flemming. Knox and the rest of the townspeople responded to treatment with an antibiotic which destroyed the symbiotes and returned them to normal with no memories of their implantation.
