While it doesn't seem like much has changed 20 years later, I have wondered how it is that hexenbiests, wesen and a grimm/hexenbiest mixture can team up to kill wesen. And this makes me wonder if some changes have occurred.
We don't know the power of the stick. It's been linked to Moses' staff which brought terrors from the sky as well as food and water, but that was speculation on the characters' part. We know Nick could create an alternate reality or reverse time, whichever the viewer believes. Could the stick be used to alter humanity so that humans are not only aware of wesen, but could live side by side with them?
