Real World References
Charlie and Charlie's Archons are references to a television series Charlie's Angels featuring 3 young women working as private investigators for their boss, Charlie, whose face is never seen on screen. If this homage continues, we will never see Charlie's face, though we may catch sight of extremities or a silhouette.
