The awed faces of the audience in contrast with the grim expressions of the royal family were fun to look at. It seemed like all of them knew the performer. They had probably all had conversations with her, sat down for tea, and spent time in each other's presence. They also all seemed to hate her.
Of course, this was different for the youngest son as he seemed to not care for one second as to whatever was going on in his family and stayed entertained at what he was watching. Not entertained... He stayed content.
