Grimm Reality Setting In For Detective Griffin

Friendly neighborhood "Grimm" Nick Burkhardt (David Giuntoli) is used to seeing the monsters inhabiting the Pacific Northwest. But as actor Russell Hornsby explains, suddenly seeing the things that go bump in the night in last week's episode has left his own character, Portland Detective Hank Griffin, feeling a little unhinged.

"Hank has lost his mind. He's questioning his sanity after having seen creatures morph," Horsnby told TV Guide. "It's taken him off of his axis. He's seeking professional help and going to therapy, seeing if he can get back his center."

Things aren't bound to get better for the beleaguered peace officer. After witnessing the transformation of a Wesen back to its human state last week, this week Griffin must come to the aid of a friend attempting to find his missing daughter. What's sure to test the detective's sanity further is that this friend just happens to also be a coyotl creature himself.

Hank's questioning of his own sanity can hardly have positive ramifications on his job performance. "He's questioning everything now: What's happening? Who's who?" Hornsby said. "Should he remain a police officer on the force or not? That's his new hero's journey."

Check out NBC's "Grimm," airing Mondays at 10/9c. The series moves to Fridays at 9/8c beginning Sept. 21.
