Q
Investigators of the unexplainable and dealing in "question mark crimes", they are a constant presence in the comic whenever supernatural events occur. They are officially a special branch of the police and operate out a basement HQ in Castletown police station, and can be identified by their green trench coats. Unofficially, they are primary agents of the Green. Jack Staff #6 (Vol.2) had Zipper Nolan discover a room full of dangerous relics and objects recovered from Q's cases, including Mr Green's cloak and shards of the Valiant Stone. In The Weird World of Jack Staff #1, Helen Morgan stated that this room was an arsenal - Paul Grist has stated the arsenal "doesn't belong to Q" . Their headquarters is portrayed as an always-dark void with green doors, as well as mysterious windows which might possibly have a dream-related function; gravity and direction seem entirely arbitrary within its walls.
