'Grimm' 'Bears Will Be Bears' sneak peek: Amy Gumenick runs for her life

Grimm continues this Friday with the next new episode, "Bears Will Be Bears." It's time for the new NBC series to take on the story of Goldilocks and the three bears, and there's a sneak peek out showing what viewers should expect when they tune in.

Season 1 episode 2 "Bears Will Be Bears" sneak peek

According to TVGuide, the second episode of the new supernatural procedural drama is going to show Nick and Hank looking into home invasions and finding "a family with a cultural background including a barbaric history perhaps best left in the past." In fact, it looks like this is their twist on "Goldilocks and the Three Bears," as the sneak peek shows Amy Gumenick (Supernatural) guest starring as Gilda.

In the Grimm clip (below), it looks like Gilda may have landed a bit more roughly than she should've, but she reassures Rocky, who's leaning out the window, that she's fine. She calls him down, but he's grabbed by something growling and pulled back inside. She hears his screams and more growling and runs for her car as something follows her. She is able to get inside and drive off, but is she still safe or will she end up in trouble again? Will the next that's seen of Rocky be when Nick and Hank investigate his murder? It looks like this should be a good episode, but will Grimm be able to do well against Supernatural, Fringe, and CSI: NY this week?
