How does Nick know that Kelly is his mom and a Grimm, if the lady in question was a top cage fighter, she could probably have taken out the half stunned Kimura? Maybe the same way that Wesen can spot Grimms applies to Grimms as well. AFAIR Kimura was not woged when Kelly fought him, so Nick would have noticed any difference.
