User blog comment:Theory of everything/Is Nick loosing his Grimm powers?/@comment-96.125.244.229-20120206055846/@comment-1966944-20120206083356

That could be dangerous, however, if he "loses" his perceptions of the creatures but retains his "projection" of being A Grimm. In essence, they would know he was a Grimm way before he would know they were a creature, which would make an interesting situation for Nick!
