Grimm not only teaches about fairytales, but chemistry, too!

This Friday's episode is riddled with the consequences of real chemistry when a Ziegevolk, a magical creature who's able to seduce women with pheromones, goes on the rampage. To track the Ziegevolk down, Nick (David Giuntoli) will enlist Monroe (Silas Weir Mitchell) to get a whiff of the suspect. Check out this first look at Grimm's special brand of chemistry:
