Sorry, I don't agree Shadow. Your implication would mean that everything alive is the foreign entity that the universe is trying to excise. Yes the Grimm are animalistic in nature (for now) and as of this episode, we haven't seen any other animals on the show but we have heard of them. Pyrrha did say they existed. The problem with your force of nature theory is that nature is alive, not the Grimm.

I think you are over-analyzing the Light and Dark. I believe this is a simple conflict between good and evil but with a twist that I have not figured out yet. Why the twist? Because when the show is all said and done, I think the Grimm won't be an issue anymore.
