Kev (The Halloween Apocalypse)

Kev knocked on Dan Lewis's door on Halloween shortly after he gave sweets to a trio of kids in appropriate costumes. Unlike them, he was "not even dressed up", though he did carry some eggs to show at people's houses. He blithely demanded of Dan that he give him sweets as well, which Dan refused to do, also warning Kev not to throw any eggs at his house. Shortly after Kev's departure, Dan received a third visit, this time from Karvanista. (TV: The Halloween Apocalypse)
