Snape stopped dancing when Yuna did, respecting her emotional needs. She was clearly moved to grief by this topic, and he briefly wondered if it had been too callous of him to ask about it. Truth be told, however, he was fascinated by her explanation, containing, as it did, so many other fascinating and unexplained concepts. Her Sending was definitely a ritual, and clearly a significant one in her spiritual culture. Yuna was clearly an important person where she came from. How different to the old days in Britain, before the separation, when the village wizard was the object of fear and hatred.
Snape didn't even notice that he still held the girl in the dance hold until she stepped away from him. Nodding, he indicated his acquiescence to her gesture of intended departure.
"You are most welcome, Yuna. I enjoyed it very much. I wish you a good night. May we meet again."
