In the episode, Nick demands to know about Juliette's return and seeks Trubel and Meisner's help in it while also going after the previous case that involves Monroe and Rosalee.
The group goes outside of the warehouse and Nick (David Giuntoli) runs off to find Trubel (Jacqueline Toboni) to explain Juliette's (Bitsie Tulloch) appearance.
Monroe (Silas Weir Mitchell) is called by Rosalee (Bree Turner) to discuss the problem with Xavier (Robert Clendenin).
Hank (Russell Hornsby) and Renard bring Xavier to the precinct and throw him into a cell until he can be placed in protective custody.
Their plan is foiled when Lucien Petrovitch (Bailey Chase), Black Claw's leader, sends a hitman to kill Xavier.
Monroe and Rosalee alert the Wesen Council, and Alexander informs them that an organization called Schwarzkralle (Black Claw) is behind the uprising, but that he cannot discuss it any further.
The episode was viewed by 3.81 million people, earning a 0.8/3 in the 18-49 rating demographics on the Nielson ratings scale, ranking third on its timeslot and tenth for the night in the 18-49 demographics, behind 20/20, a rerun of Hawaii Five-0, a rerun of Blue Bloods, Dr. Ken, Last Man Standing, MasterChef Junior, Undercover Boss, Dateline NBC, and Shark Tank.
But no, Grimm has exhibited a clear willingness to go beyond that, cutting a bloody swath through various parts of its cast and setting important landmarks ablaze in the service of drama.
The Hexenbiest that was once Nick Burkhardt's girlfriend has been hammered into a nearly emotionless killing machine by Hadrian's Wall to combat Black Claw.
The ISIS/Black Claw parallels were so overt they kinda hurt and the shocking murder of the entire Wesen Council by one of their own upped the intensity and urgency that the beginning of the season was missing.
