Honestly, this Nationals was always going to be so dangerous. So many skaters train on the same ice as Alexa and Brandon including Mariah Bell and Nathan Chen. This Nationals isn't safe. I would still send K/ F to the Olympics. They had one bad program at Warsaw Cup ( a terrible event) but other than that they are the most reliable, balanced team. The best bet for the Olympic team event. If Brandon is vaccinated, it is highly likely he is asymptomatic especially if he caught COVID on the tip to Nashville. No evidence he had any idea he was ill. It is quite inappropriate to assume he knew. However, this event is a recipe for disaster. Omicron is so contagious even my friends who are careful, wear mask and are vaccinated are catching it and they have managed to avoid being COVID positive for the last two years. It's impossible to hold a safe event in these circumstances.
