"Grimm" season 4 continues to follow Juliette as she succumbs to her terrible and rather dangerous fate. As she transitions into a Hexenbiest, the veterinarian, who no longer sees the use of resisting her destiny, starts to depart from her humanity and the consequences of this will be seen in episode 18 titled "Mishipeshu." 

After attacking Adalind to settle the score, the vengeful Juliette looks like she is headed to jail for such actions. The synopsis for the new "Grimm" installment reveals that her "erratic behavior will land her on the wrong side of the law" and that does not sound good at all. 

Needless to say, Nick's relationship with Juliette has never been more complicated ever since the love of his life turned into this almost ruthless witch-like creature. It is exciting (and difficult at the same time) to see whether or not Nick will forget what the law books say to save his Juliette. 

Speaking of Nick, the police detective's problems never seem to run out as seen on recent "Grimm" installments. Episode by episode, his troubles just grow worse and worse. In episode 18, he and his partner Hank unknowingly lead themselves to unimaginable danger. 

The NYPD duo are tasked to investigate a homicide and as they do their job, they find themselves in the "dark and mysterious path" of a power quest devised by a local Native American. It is hard to imagine how the two are going to get out of this one. 

Meanwhile, Rosalee and Monroe have a brand new task to take care of, but its success requires the services of Captain Renard. Whatever that special mission that requires the help of the magic-wielding police captain is, there is no telling but it sure sounds like a lot counts on it. 

Episode 18 of "Grimm" season 4 titled "Mishipeshu" will air on April 17.
