Are there any confirmations on who the last spot at Nationals will go to? Tarusina came 2nd at the Russian Cup but Serafima has a GP now, so did Serafima automatically get the last spot due to her assignment? Also is Fedichkina allowed to compete as a Junior at Nationals since she didn't qualify for seniors?
Yes, Fedichkina is qualified for Junior Nationals.
