The Grimm can actually see.

"so grimm have eyes, huh? why didn't the nuckelavee stopped moving and started looking anywhere? Keep in mind that this is fiction. Nothing makes sense and you should know better. "- Umbrellish.

This is the counterarguement. Some might consider this a very excellent point. I do too, but that doesn't stop me from feeling attacked and humiliated. That's why I'm going to prove him wrong with one simple fact.

If the Grimm could not see, then how would they walk without bumping into things like buildings or mailboxes? The only other possibility I see is every Grimm having ecolocation.

What I believe is that Grimm have a sixth sense that allows them to sense negative emotions in a manner similar to smell. Ren's semblance cuts off the source of the smell and thus, the Grimm wonder where the yummy emotions went. (Not that Grimm eat).

No one's mannerisms completely change when Ren uses his semblance. Young Nora admits she's scared, and Jaune still says that everything's going to be okay. That's why I believe Ren's semblance to mask and only slightly hinder emotions, making the Grimm have no interest in the cloaked people.
