I saw video of Mariah hugging Nathan Chen after his win the other night. She couldn't stop! She was also massaging his shoulders. It looks like she has a crush on him.
Mariah and Nathan are old friends and training mates who lived in a bubble with Michal Brezina and his wife for safe training. If hugging were an indication of a crush, Jason would be crushing on everyone in the skating world
When skaters publicly disclose relationships, we can talk about them on Goldenskate. Otherwise, not so much.
