New spoilers reveal that the next all-new episode of NBC's "Grimm" will be very intriguing, as Juliette will actually consider living her life as a Hexenbiest while Nick and Hank race against the clock to save Monroe from evil Wesens.

During the last episode of "Grimm," which was titled "Chupacabra," Monroe was kidnapped by a Wesen hate group, Juliette became a Hexenbiest and Wu discovered the truth about Nick.

In addition, Monroe and Rosalee suffered from another attack by the Secuddum Naturae Ordinem, a purist group that targets interspecies marriages. Not only was the couple forced to postpone their second attempt at a honeymoon, but one of the KKK-like group members kidnapped Monroe.

Another unexpected twist occurred when Juliette transformed into a Hexenbiest.

According to a press release issued by NBC, Nick and Hank will do all they can to rescue Monroe, while Juliette will embrace being a Hexenbiest in the next episode, titled "Wesenrein."

"Nick and Hank will have to save Monroe from the Secundum Naturae Ordinem Wesen while Juliette considers life as a Hexenbiest," reads the synopsis, according to Hollywood Hills.

"Grimm" star David Giuntoli also dropped spoilers about Adalind and Wu's coping with the world of Wesen.

In an interview with TVLine, he revealed that "there are even more side effects to Juliette turning into Adalind." He added: "There should be, in the Spice Shop, some type of side effects list. We're in the 21st century."

When asked if and when Trubel will return, he said: "I don't know. We will not be seeing Trubel in the next episode." However, he added that "hopefully, we will be seeing her down the line. Even more hopefully, she gets her own spin-off show, which I think is great. I can do guest-star [appearances] every now and again. The aging Grimm. I can put my children through Ivy League universities by going on The Trubel Show," he joked.

Giuntoli also hinted about how Wu will deal with knowing the truth about the supernatural activity in Portland.

"I don't want to speak for him, but when he's been through so much torment and mental anguish that the news that this is in fact for real is a little easier to swallow. Reggie's been playing it like he's got an eye on us, on Hank and myself a little bit. But he is tentatively accepting this as OK. This is all making sense."

Lastly, he confirmed that Nick and Hank will do all they can to make sure Monroe and Rosalee get the honeymoon they deserve.

"Of course they're going to get their honeymoon!," he said.

"I assure you that Hank and I will go to every length to get them onto that stinkin' plane to wherever they decide to celebrate."

Season 4, Episode 8 of "Grimm," "Wesenrein," premieres on NBC on Friday, Jan. 9, 2015, at 9 p.m. ET.
