Alone in her dressing room, Christine hears the voice of Erik Destler, revealing he is her teacher and an angel sent by her deceased father. Destler encourages her to practice Carlotta's part of Marguerite in "Faust", saying that only she can sing the part. Christine complies. That evening, Carlotta discovers Joseph's skinned (but barely alive) body in her dressing closet. The event causes her to scream and lose her voice. Christine is cast in the role of Marguerite, which causes panic to the opera house owner Martin Barton (Bill Nighy), who favors Carlotta and the prestige she brings to his opera house.
