'Grimm' Season 4, the NBC supernatural drama, has taken a break for holidays but is set to return on January 16, says Celebeat. When the show returns, Nick and Hank have to rescue Monroe from the Secundum Naturae Ordinem Wesen while Juliette considers life as a Hexenbiest. For those that don't know, the Wesen hate group is known as the Secundum Naturae Ordinem Wesen (SNOW).

Episode 9 is titled "Wesenrein" - Monroe (Silas Weir Mitchell) had been being abducted by the Secundum Naturae Ordinem Wesen and Juliette (Bitsie Tulloch), after helping Nick (David Giuntoli) become a Grimm again, finds out that she herself has turned into a Hexenbiest.

The teaser trailer for the next episode shows that Nick's resolve to keep his balance in being a Grimm while also being a cop will be put to the test as he tries to save Monroe. As the narrator reveals - Nick is living on two sides of the law, and would be left with not much choice. He would have to cross the line and the question is - can he save Monroe before paying the ultimate price?

Juliette is in a dilemma because she does not want to become a Hexenbiest. She is basically a kind of Wesen, or witch and her boyfriend's fate is to kill them. That, obviously, is kind of scary and naturally she will try to conceal the fact as she wants to figure out a solution.
