It was stated in one the interviews that the additional health issue that Alyona had was her nerves. I think we all had a glimpse on what's happening with a teenager who was winning, was on top and then slipped down. It's a mental crisis.
I think this situation highlights the difference between methods of training really well. I'm a university lecturer and supervise a lot of students. I worked in Russia and in Western Europe. The key difference in supervision is who takes responsibility for result (a student's grade). In Russia it's supervisor who is responsible to a large extent. In one of Western European countries, where I work, I only offer students advice and options, and it's up to them to decide whether they want to take my advice or not. It seems to me that it's the same in figure skating training methods. Eteri takes responsibility. Plushy gives it to student.
Eteri has been blamed for strictness of her method, and her students consistently deny this in the interviews. I think Eteri doesn't need to yell at students or be harsh or anything like that. It's a combination of external and internal motivation that makes them to obey. Plushy's method is mostly based on internal motivation. He provides resources and it's up to student to decide if they want to use them. You can probably expand this: Plushy's method is similar to North American, and Eteri's is the classical Russian method.
