“Paper Moon” is a good old-fashioned Monster of the Week Supernatural episode. The boys’ development as hunters and brothers is shown during the opening montage. The reference reminds us why we love Supernatural so much: hunting provides excitement and suspense, while the characters’ relationships provide meaning and investment for the viewer. We get a chance to revisit Sam and Dean’s previous dealings with werewolves—mostly involving Sam or Dean killing them, but also showing how their relations with lycanthropes became increasingly complex over the course of their hunting career. Werewolves have been a staple of Supernatural’s terrestrial monster repertoire from the beginning.
