J. J. Johnson, Watch Constable
Constable Corporal Johnson (no one calls him J.J.) is based in Normaltown district. He’s known to have been present at several recent Watch actions involving our protagonists, including a brawl at the Frog and Toad Lodge and the sting operation at the Toddy Toe Toddle that ensnared Lord Kochilar and resulted in his promotion to Corporal. He might also have been present at the expedition into the sewers that resulted in the Watch deputizing Big Stinky.
Corporal Johnson is a physically unremarkable individual who easily blends into a crowd. He seems thoroughly unflappable in any crisis situation (meeting an otyugh at close range, nearly getting set on fire, arresting his superior officer) and was remarkably competent for a constable. Apparently his supervisors agree, as he has since been promoted to Corporal.
