It's the inconsistencies that really bother me with relation to how creatures identify a Grimm. The Jagerbars obviously knew that Nick is a Grimm and told him so when Hank was out of earshot, as had the eisbiber. But the ziegevolk and the geiers didn't show any indications that they knew Nick's a Grimm when he was interacting with them, even when they were alone. Of course, this adds to the shock factor in the end when everything's revealed but this also kinda makes it somewhat convenient and becomes a poor tool to add excitement. I am not for a lengthy and boring exposition of everything Grimm all at once, but when you introduce a 'new' mythology it's important that certain facts are handed over outright to explain the logic and for sake of continuity since every thing that happens to a single episode should somehow support what happens in the next or give reason to what happened in the previous one. It is fun to theorize, though. But I seriously wish the writers would explain this to make it canon. Grimm is FUN. :)
