And glass is not Cinder's Semblance. Ruby saying "I don't think it was her Semblance" was the writers' way of telling us that glass is not Cinder's Semblance. The problem with Watsonian statements is that those depend entirely on the perspective of the character. An "it's not her Semblance" from a writer or voice actor is hard to argue against. An "it's not her Semblance" from a character in-show that wasn't even entirely sure is different.

How does Ruby know for sure Masked Person X didn't use her Semblance? How does Ruby even know that stranger's Semblance?
