Nick investigates the failed attempt to murder feral Ian Harmon, who seeks help from ex-lover Rosalee, who brings in Monroe, who turns to Nick. He finds the feral hit-man Edgar Waltz is a Hundjäger ('canine hunter'), a ruthless breed used by the seven competing royal families, who demands police captain Renard's help. Waltz stops at nothing, threatening with city-wide slaughter and kidnapping Rosalee to get his prey, but Nick, Ian and Monroe still fight back, for once overruling human law. Written by KGF Vissers

Did You Know?


The opening quote and some loose plot points come from the fairytale "Iron Hans". See more »


Edgar Waltz: You may think I'm a monster, but what I am is necessary. No society would survive without order. Free thought is not free. There's no such thing as revolution. The oppressed always become the oppressors and the cycle repeats itself over and over. The only way to win is to stay out of the cycle. You don't understand a word that I've been saying.
Rosalee Calvert: I'm sorry. I wasn't listening.

Crossing the Line
10 June 2014 | by (Rio de Janeiro, Brazil) – See all my reviews

A man named Ian Hamon is being hunted down by the Verrat's agent Edgar Waltz and is wounded at Portland's bus station by a bullet and loses his backpack. Waltz meets Captain Renard seeking for help to capture Ian but his request is turned down. Meanwhile, Ian, who belongs to the Wesen Resistance, goes to the spice shop and Rosalee, who was his lover in the past, calls Monroe to help her to remove the bullet. Waltz kills a man and leaves Ian's passport in the crime scene to force Renard to chase him. When Nick arrives at the spice shop, he tries to attest Ian, but Rosalee and Monroe testify that he was unconscious with them when the man was murdered. Soon Waltz confronts Nick while Ian needs a new passport to leave the country. Nick has to take a decision and cross the line as a police detective.

"Cat and Mouse" is a good episode of Grimm, especially because of the conflictive situation faced by Grimm. Now his knowledge of the Grimm world interferes with his professional life and it is visible that he does not totally agree with his last attitude. My vote is eight.
