Is another Grimm back in Portland? The episode synopsis for 2×10 “The Hour of Death” and 2×11 “To Protect and Serve Man” reveal the Wesen’s are in danger. Plus Hank will be second guessing an old case now that he knows about the Wesen world.

“The Hour of Death” episode synopsis:

A SERIAL KILLER DESCENDS ON PORTLAND AND THE WESEN COMMUNITY IS IN GRAVE DANGER — 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.

“The Hour of Death” will air Nov. 2 at 9 P.M. on NBC.

So far, fans have only gotten to meet one other Grimm in the form of Nick’s mom and she wasn’t exactly friendly towards the Wesen. Even to those who were kind, like Monroe and Rosalee, she still seemed to itch at attacking. Could another Grimm in town threaten Nick as he isn’t exactly like all the rest of his kind?

“To Protect and Serve Man” episode synopsis:

HANK’S KNOWLEDGE OF NICK’S WORLD HAS HIM SECOND GUESSING A PAST CASE — JASON GEDRICK AND LISA VIDAL GUEST STAR — Hank (Russell Hornsby) starts reflecting on an arrest he made earlier in his career regarding a man (guest star Jason Gedrick) who committed murder claiming “self-defense against monsters.” With the man’s death sentence rapidly approaching and the knowledge he’s recently gathered from Nick (David Giuntoli), Hank begins to wonder if there was more truth to the man’s seemingly absurd story then he once thought. Back at the spice shop, Monroe (Silas Weir Mitchell) finds himself involved in a situation he never saw coming. Bitsie Tulloch, Sasha Roiz and Reggie Lee also star.

“To Protect and Serve Man” will air Nov. 9 at 9 P.M. on NBC.

Will Hank’s knowledge about the Wesen world help or hinder him? When he looks back on a case of a man who claimed a monster attacked him, will he be able to get to the truth?
