After ditching the lunch where she was supposed to announce her engagement to Billy Wallace, Princess Margaret heads home to let loose in her chambers. We see the moment through the eyes of one of the women on her staff. She comes upon the royal princess drinking, smashing things, and stumbling around her room as Ella Fitzgerald's "Angel Eyes" plays in the background. While the queen's steely demeanour means we see her bottle up her frustrations throughout the series, Margaret is her opposite; she isn't afraid to let herself fall apart in public or in private. This scene, perhaps more than any other in the season, helps to define the difference between the two sisters and cement our love for Margaret's relatably messy life.
