Press Conference with Alexandra Trusova, Evgenia Medvedeva and Mariah Bell, winners of ISU Grand Prix - Rostelecom Cup 2019. (English translation by altroscope) Mariah Bell's answer I had to translate back from the Russian translation :)
I don't know what you're talking about, but it's because I'm Japan and I don't understand Russian. However, the impression I get from the video is that of the strong eldest daughter Dmitry Medvedeva and her younger sisters.
