I don’t know what the boys were implying with that, but Evgenia’s body has changed over the past year. I thought it was the combination of weight training and working with a nutritionist.
It starts at 16:30, and but is fully mentioned at 17:10. They were talking about Medvedeva's technique really started failing last year but she managed to eke out wins despite it, and that there was more going on than just a foot injury. The implication is that the old coaching team tried to delay "what is inevitable" for as long as possible so that her technique could hold through the Olympics.
I hear Zhenya choreographed herself? If so I think she's got a lot of talent in that area! I wonder if she can choreograph her own competitive programs some day (although that's probably waaay harder to do then an ex, what with all the levels and rules you have to meet!).
The truth is really a trigger for some human beings.
