The season finale of NBC’s surprise hit Grimm is upon us, and though Nick (David Giuntoli) has managed to keep his Grimm reality from Juliette thus far, might he be out of options?

In this exclusive clip from the season ender, Nick’s a little concerned after his girlfriend gets scratched by a cat — but we’re not talking about your average fluffer. In fact, he’s so concerned that he makes a shocking move: He tells her Adalind is a witch.
