On the figure skating pairs medal podium Monday evening, half of the six skaters standing before the crowd with medals around their necks were Russian-born athletes. The gold medal went to Japan’s Riku Miura and Ryuichi Kihara, who had a world-record-breaking free skate score and finished 10 points ahead. Silver went to the Georgian pair, Ms. Metelkin and Mr. Berulava, both Russian-born skaters who train in Perm, Russia, with Russian coaches. And the bronze went to the Germans, Minerva Fabienne Hase, born in Berlin, and her partner Nikita Volodin, a newly minted German citizen.
