* I only caught his name when they were announced, but this was his partner from last season, so I assume it was her.
There was one more couple but I missed them. Also, Shanaeva/Naryzhnyy had announced their RD as Bonnie and Clyde already. The pieces used are ‘How ‘bout a Dance’ and ‘The World Will Remember Us’
