I just have watched an interview with Yana and Rita in which they talk about the OG.
About her mistake, Yana said she could have done that element 10 times per training and not 5 as she regularly did. But still, she has done that element since she was 13 and doesn't remember any problem with that. She says it just happened that way. She wasn't angry, but disappointed. After her clubs routine she didn't even want to get up from the carpet, but her coach Karpushenko told her that she didn't lose everything and she still had to do a great ribbon routine to make sure she was going to have the silver medal. The warm up before the ribbon routine was horrible for her, but when she entered the carpet she felt she smiled for the whole arena. She really enjoyed the ribbon.
Rita says everybody ask them if they still are friends, or that if they just pretend to be friends in front of the cameras. Their friendship remains the same as always, they always support each other. When the finished the competition, they gave a big hug and said that finally they did it, and they finished all that. She says they cried because of sadness but also happiness, Yana was happy for Rita and Rita was happy for Yana because even if she was there for the gold, she still is the silver medalist at the Olympic Games. That night they couldn't fall asleep. She called Irina Viner, who said "Such a spectacular ending with the ribbon".
You have the link to the video in my bio, that channel (RG Details) has translated many interviews to English, so it's very interesting, I recommend you. #ritamamun #маргаритамамун #мамун #янакудрявцева
