That inconsistent accent bugged that mess out of me especially because there was no reason to it. Not to mention, everyone just seemed to speak lifelessly..without any real passion, inflection, or real human emotion. I'm DEAD at the description of the mom's voice acting. You ain't right Spirit XD.

I can dig that idea. But, it seems that while Grimm are more attracted to negativity, they aren't blind to those who don't feel it. This is evident in the Emerald Forest when Yang was attacked by a random Usar. She wasn't scared at all, but it still attacked her. Also, the other attacks in the forest were done due to mere human presence in Grimm vicinity. I dunno. Maybe they retconned the Grimm. *shrugs*
