I'm curious too; was she the mother of one of the dancers? and what did she say? Excellent dance! This is one of the aspects of WCS that makes it so wonderful - the spontaneously free creativity that either partner can express.
They shoudl have a serious dance then a dance with comedy.. Not a fan of the comedy. Dancing..its rather silly. If I'm watching professional dance competition I prefer a more serious dance not anything silly or comedic..just my opinion We all have one....Just Saying
