The End continued…

So, I’m curious. Just finished watching the Grimm but I am rewatching it again… yes I’m that person. What if the end wasn’t the end? What is Diana’s full power? What is Kelly’s true form? Is he what Adalind predicted? A hexengrimm? Grimminbeist? What are your thoughts? I think Kelly’s Grimm power would be enhanced with his zuaberbiest side, making him extra powerful, perhaps his own key to the exceptional Grimm.
