that's never gonna be a breakaway pop hit". With a characteristic dry demeanor, Giles explains that he overheard the information about Sunnydale residents spontaneously combusting as he was eavesdropping upon the police taking "witness arias". In her opening number, "Going Through the Motions", Buffy sings that she feels as though she is playing a part: "nothing here is real, nothing here is right". The song introduces the character's emotional state but also removes the barrier between the actor and the audience, as Gellar the actor portrays Buffy, who feels she is merely playing the part of the Slayer. This hints to the audience that the episode's musical format is strange to the actors and characters. According to Buffy essayist Richard Albright, the lack of polish among cast members' singing voices added to the authenticity of their breaking out into song for the first time in the series. Whedon included self-conscious dialogue and references about the characters being in a musical and showed their reluctance toward song and dance, so that the audience would feel more comfortable with the improbability of such a thing happening on the show. Themes The dynamic nature of the characters was a unique element of writing in the series at the time. Once they were established in the twelve episodes of the first season, characters began to change and relationships were developed in the second. This continued through the series to the point of unpredictability that sometimes became unsettling to fans. Buffy essayist Marguerite Krause asserts that the monsters and demons faced by the Scoobies are thin symbolism for the show's true focus: relationships and how to maintain or ruin them. Common among most of these relationships—romantic, platonic, and familial—is, according to Krause, a "failure to communicate, lack of trust, [and the] inability to envision or create a viable future". Miscommunication is worsened or sustained through multiple episodes and seasons, leading to overwhelming misunderstanding and critical turning points for the characters, some of whom do not recover. "Once More, with Feeling" propelled the story arc for season six by allowing characters to confess previously taboo issues to themselves and each other. Whedon commented that he was "obsessive about progressing a plot in a song, about saying things we haven't said", comparing the musical theater format to the fourth-season episode "Hush", in which characters begin communicating when they stop talking.
