Best episode so far. The animation was top quality. Ragyo being Ryuko's mother has caught me off guard, I totally expected Satsuki and Ryuko to have the same father. That is still possible though
Notice that unlike Satsuki Ragyo uses the full power of Junketsu - all the blue lines on it are glowing like the red lines on Senketsu.
I wonder what will happen to the sisters now. Satsuki will probably be rescued by the elite four and Ragyo will try to pull Ryuko to her side. She definitely isn't going to take it nicely.
