I agree that she took the news quite well. I think being an orphan played a big part in that. She has already lost a mother, and she was in the orphanage until her teen years, so she became very self-sufficient. On top of that, her chess winnings were supporting the household anyway, so she didn't have to worry as much about who would take care of her now. She's also extremely mature, basically a 30-year-old in a 16-year-old's body.
