Their source is the TSL bs we've heard before: that Sasha isn't speaking to Sergei. Which somehow gets extrapolated to "Sasha is returning to Eteri because she doesn't want to be around Kostornaia". Because apparently "Kostornaia is the primary reason for her departure from Sambo 70 and now she has to skate with her again. But Sasha was never in Sergei's primary group, she went to be coached by Plushenko. And Plushenko has Sasha and Aliona in two separate groups. Also, those rumors that she isn't speaking to Sergei? Based off the fact that Sasha and him didn't communicate at test skates. Even though he is not her primary coach. We didn't see Sasha's primary coach speaking with Aliona while there. We also see Dudakov and Daniil split their time between skaters at competitions. Is that evidence of tension or just divided attention? And she doesn't appear in Angels of Plushenko videos which is how we know she isn't speaking with Sergei? She never did, maybe briefly at the beginning of her transition she was in some videos, but not with Sergei as far as I can recall. And Aliona is now the one who has to prove herself, hence the increased social media presence. Same as how Sasha got before test skates. Maybe she doesn't want to be filmed all the time. Who knows. Her transition was very well thought out, and given the appearance at test skates, I'd think we'd have to see a disastrous season for her to return to Eteri. It's one thing to transfer outside the transition window while still in the off season. It's another to transition after the season has already started. And with her complain about not getting enough attention + that Medvedeva is now there (making the top group number of girls the same as it was when she left, just swap Medo for Kostornaia) it would make no sense. And if it does happen, then who should care. It is a discussion between the skater and coaches about what is best for them.
