This post lays out a thought process for distilling themes and finding characters from monologues. I’m careful when I teach it; I’d rather my players be present in the show and not be doing math on the side lines. I’ll introduce this concept in class, do some exercises that use it explicitly but I always remind the student that the audience (and myself) won’t be judging them on their inspirations but on how well the scenes are played. However a player gets their inspiration, whatever technique they use to cook it, it is the scene that occurs onstage that is most important.
EDIT: More stuff from Bill on separating specifics on Reddit.
