When a brutal vigilante homicide is made public, it sends Portland's Wesen community into a frenzy. As Nick (David Giuntoli) investigates further, he discovers a pattern similar to that of a particularly brutal line of past Grimms. Is there another Grimm in town, or is Nick dealing with a sadistic copycat? Meanwhile, Captain Renard (Sasha Roiz) takes it upon himself to offer Juliette (Bitsie Tulloch) comfort in handling her ongoing dilemma with Nick. Russell Hornsby, Silas Weir Mitchell and Reggie Lee.
