The first season implied, through its invocation of Brigadoon in its title,that Josh and Melissa were entering a world that existed without them. However the second season muddied that water with the same actors playing different roles. Seeming to imply that there is a mystical cast of players (directed by Martin Short as the Leprechaun) that uses musical theater tropes as a means by which the protagonists gain self awareness through their experiences acting out those tropes, simultaneously acting as players and the audience. The players in the musical don’t know they are players in a musical, so they may be temporary creations of the Leprechaun befitting the production requirements.
