I'm not sure skating with fire to music written in memory of someone who has been dead only a few days is called for here or even appropriate. Grief slows down all the biological and mental processes of the griever. Some say she is disengaged: that is the status of most people in early grief, a state of shock and lack of engagement with the world. I doubt seriously that Yu na has done all this kind of analysis, and what is happening is others are projecting themselves onto her. As Freud allegedly said, sometimes a cigar is just a cigar. Very few, if any skater, is an actress who can really bring a fully nuanced performance to a program. I would be interested to know what kind of conversations she and David had about how the performance of this piece was to be approached. Considering my views on grief and its aftermath, she is doing an excellent job, whether that is her actual approach or not.
