What's with that symbol?
Grimm's new mystery will have Nick (David Giuntoli), Hank (Russell Hornsby) and Wu (Reggie Lee) digging in the ancient past - 495 B.C. to be precise.
The victim-of-the-week is found crucified in a barn with an upside-down triangle carved into the wood above his head. Some digging reveals that the symbol is an ancient religious stamp meaning water and dates back to ancient Greece. The poor victim was used as a sacrifice in a cult ritual.
The big question is: Is this cult related to the Black Claw?
Tune into Grimm Friday at 9/8c on NBC.
