After listening to the Eurosport commentary and this very recent video...

My takeaway is that perhaps it was too tough being with Alijona.
What's interesting is that Eurosport commentators say at the end that their technical content and arrangement of it was bizarre. What was submitted days before for their technical layout is not what they performed.
They also thought was strange for 2 throws back to back. I however don't feel that is strange but VERY Alijona. She likes throws at the end of a program. I remember at last Olys withRobin she went for a throw 3 axel as the last element.
It seems for me that Alijona known for being very tough was probably too much for them. The above video is very interesting because they are wise enough to know what they were getting into even moving to the Nebelhorn town but in the end it didn't work.
Alexa really admired Alijona.
