Learn what mission Monroe will undertake to help Nick and Hank solve a crime on this week’s episode of Grimm.

In “The Good Shepherd,” Monroe will be going undercover for Nick and Hank to investigate a church run by a Blutbad. The Blutbad, Lyle Calvin played by Jonathan Scarfe, is also the reverend of the church. At first it’s the reverend Blutbad himself who calls the police in order to report a robbery at the church. However, Nick quickly becomes suspicious of the Blutbad who claims to be reformed. Kristina Anapau will be guest starring in the episode as the girlfriend of the Blutbad, Megan Marston.

In the sneak peek of Grimm, Monroe identifies the Seelengut as the Wesen creature that Nick and Hank saw at the church. In the drawing he shows to Monroe, the creature that appears to be sheep-like. Hence the title of the episode. Monroe tells the pair that the Seelengut like to stay close to one another. He also states that they aren’t the type to be violent, but to not to underestimate the herd mentality. When Nick asks about the possibility of a Blutbad leading the group of Seelengut, Monroe replies, “Are you serious? A Blutbad? That’s like a recipe for lunch!” Nick explains that the Blutbad claims to be reformed like Monroe, and is wondering if it takes one to know one.
