And we also have the fact that Cinder used a glove that had a Grimm halfway come out of it, and then that glove dissolved, followed by a tattoo appearing on her back. And Salem was saying "it" could sense Cinder's trepidation and that Cinder needs to make "it" dread her. So I wouldn't be surprised if the Grimm beetle is actually inside of Cinder.
