Mathman,
I don't think so. Stephanie is from CA and trains in Utah. Blake is from PA and trains in Delaware. Their bios from Nationals did not have a link.
However, Blake is an incredibly talented young woman. She came in 2nd in Novice at US Nats and with her partner Calvin Taylor came in 8th in Junior Dance at US Nats.
Bravo for her at the Triglav Trophy! And to the winner Ashley Wagner!
Our Novice and Junior Ladies and Men are going to be fun to watch over the next few years, they are all amazing.
