User blog comment:RWBY Adam Taurus/Cinder and Glynda/@comment-24088073-20131109082707

I guess that you could make a connection between them. I certainly noticed Glynda's reaction to Cinder's appearance, but this is more likely due to the fact that Glynda knew she was up against a powerful enemy. So far, we have seen that all dust wielders are capable of using it very effectively, so this was a more likely possibility.
