As for Medvedeva representing Armenia, here’s what Ari Zakarian said about this possibility (apologies if it was already posted, didn’t read the whole thread):

“Zakarian said that it is pointless to chase after Medvedeva. Yes, her father is an Armenian, his name is Artur Babasian. I don’t even know how to say that: he went to live in Russia, Evgenia was born, and soon after he has divorced her mother. Evgenia has now her mother’s last name. It’s not hard to imagine what a scorned woman can think about Armenians, and what exactly she tells her daughter. Evgenia lives and trains in Russia, she is financially set and has all the necessary training conditions, and therefore, does not need the support of the Armenian community. Our informed sources tell me that her monthly salary is equal to the whole budget of the Armenian Figure Skating Federation. I think it would be better if people who want to help, helped struggling Armenian skaters instead.”
