I don’t think so. In most videos, i.e. Sophia’s tips & tricks she speaks in the same high-pitched voice. Maybe she tried to lower it for the interview?
I was wondering that too!! I think someone who went to the competition said their choreography was very similar, but not exactly the same. Abby probably cut the front aerial out of Chloe’s solo - I bet that if Chloe did do the front aerial they would’ve shown it to show that Chloe has it. :)
