User blog comment:Theory of everything/Is Nick loosing his Grimm powers?/@comment-96.125.244.229-20120206055846

I agree with Bob, but you have to remember that Nick was just getting his powers in the first episode, so he could probably see them because he was breaking them in. I wouldn't think he was losing his powers, anyways, because it seems he can now sort of 'project' his Grimmness around a bit so that other creatures can see what he is - like the Organ Salesman and the Nurse.
