'Grimm' Season 4 Spoilers, News: Nick and Co. Pay the Newly Wed Couple a Visit

Honeymooners Monroe (Silas Weir Mitchell) and Rosalee (Bree Turner) will once again be called for their help in this week's showing of the hit supernatural TV drama series "Grimm" Season 4.

TV Line posted a sneak peek for tonight's episode. The video showed Nick (David Giuntoli), Hank (Russell Hornsby), and Wu (Reggie Lee) heading over to the couple's home.

Their purposes, apparently, are for them to congratulate the newly wed as well as to ask for their help about a disturbing supernatural occurrence.

Upon arriving, Monroe asked the freshly-initiated Wu about how he's doing now that he is deeply involved with Nick and the others in this bizarre monster-hunting gig. Wu assures them that he's holding up just fine.

Meanwhile, the homicide detective went through the details with Rosalee and Monroe telling them about this mantacore who was suspected of killing two fortune tellers.

Rosalee chimed in with the group to educate them about the Wesen Council Law and the consequences violators could suffer. The discussion went further and it appears that the newly in-the-know Wu is somewhat worried about what he had heard.

A synopsis for this week's segment was posted on The Futon Critic and it reads:

"Nick and Hank investigate a series of murders that lead back to the Wesen Council and a mysterious bounty hunter (guest star Arnold Vosloo). Elsewhere, Juliette's (Bitsie Tulloch) meeting with Henrietta (guest star Garcelle Beauvais) brings about more disturbing news than she was expecting. Meanwhile, Adalind (Claire Coffee) and Viktor (guest start Alexis Denisof) make their way back to Portland."
