That is a good question. I should rewatch that scene. Perhaps Raven didn't come into view, the animators didn't show it, she wasn't close enough or she could already be in the Vault...Or you used found a major flaw in my theory. That's also possible, of course.

But that does bake the question: Salem did state that Cinder was weak to the Silver Eyes because of the Maiden powers. If it was because of the Grimm beetle, why didn't she mention that?
