Julia left like half a decade ago, then got treated for an eating disorder and moved on with her life in a major way.
Eteri mentioning Julia at all is Eteri's problem alone. Normally I would say Eteri "needs to get a grip" but probably "let it go" is more appropriate.
Once Julia put forward a requirement not to go out on the same ice with Zhenya ... Then Zhenya refused to skate with Alina ... And now from Alena we have received a whole list of girls non grata. That's where we parted with her ...
The girls change but the behavior remains the same.
I am going to assume it is the team that elicits the behavior from the girls because I don't think the evidence indicates the ice and facilities elicit the behavior.
