"Grimm" Season 4 premieres on NBC in October. To delight fans, the paranormal show's producers and cast attended the SDCC and dished some spoilers and teasers. Since Nick has been "un-Grimmed," his Wesen friends Rosalee and Monroe seem to be unable to fully enjoy their honeymoon.

Spoiler alert: This feature contains Grimm Season 4 spoilers. Read at your own risk.

"The Grimm has been un-Grimmed... things are turned upside-down," Silas Weir Mitchell gave a quick preview of Grimm Season 4 in this TVGuide report. This un-Grimming affects his character Monroe's honeymoon with Rosalee (Bree Turner), of course.

Monroe and Rosalee try to enjoy their honeymoon "but things are complicated in Portland these days," Mitchell said.

"We are exposed now as Wesen harboring this Grimm," Turner added, referring to the incident at the wedding in the Grimm Season 3 finale. Their Wesen friends are expected to demand answers. Naturally, these things would get in the way of the usual post-wedding schedule.

"Trubel is now my seeing-eye Grimm," David Giuntoli said, confirming that Trubel (Jacqueline Toboni) is playing a bigger role in Nick's life in the beginning of Grimm Season 4.

"I think we'll try to find some interesting way to bring [Captain Sean Renard] back," Sasha Roiz said, teasing what happens next to the Portland Police captain. No big details there, but many fans are relieved to know for sure that Sasha Roiz and Captain Renard are in for Grimm Season 4.

More Grimm Season 4 spoilers: Captain Renard's mom will be introduced. Showrunner David Greenwalt assured fans Adalind's (Claire Coffee) baby will be seen again next season. Viewers will see a "Chupacabra" and an Octo-Man. More will be unveiled about the seven keys.

Those curious about Sergeant Drew Wu (Reggie Lee) has to wait until Grimm Season 4 premiere if he would finally be part of Nick's "core support group," which currently involves Julliette (Bitsie Tulloch), Hank Griffin (Russel Hornsby), and the Wesens.

Meanwhile, in an earlier report from TVLine, someone from "Orange is the New Black" is joining the cast of Grimm Season 4. Elizabeth Rodriguez is playing Special Agent Chavez, an FBI agent who will look into Weston's (C. Thomas Howell) death. Rodriguez "has a lot more invested in (and a lot more to offer to) this case than anyone could possibly have guessed."

Grimm Season 4 premieres on NBC on Oct. 24 (Friday), at 9/8c.
