The fourth season of "Grimm" will air on Oct. 24 and will pick up where the third season left off.

Last season, huge things happened in Portland, Oregon where fans witnessed a wedding, a possible death, and a one night stand. Below are the top five things that every fan should know about the upcoming season of "Grimm."

First episode is a continuation of season 3's final episode

Unlike many speculations, there will be no time jump in the new season of "Grimm." The premiere episode of season 3, entitled "Thanks for the Memories," will be a continuation of last season's finale "Blonde Ambition." Fans are dying to know whatever happened to Renard (Sasha Roiz) after he coughed blood.

Nick lost his powers, but not upset

In the final episode of season 3, fans saw Nick (David Giuntoli) lose his Grimm powers after he slept with Adalind who was pretending to be Juliette. However, he will not be upset about it.

"This is much better for his personal life. After a long and bumpy road, he and his girlfriend, Juliette, are finally in a true partnership. They don't need this Grimm stuff causing emotional chaos. There's no way Nick will lose Juliette again. He'll just have to fight crime the old-fashioned way," Giuntoli told TV Guide.

No Honeymoon for the newlyweds

Another great thing that happened last season is that Monroe (Silas Weir Mitchell) and Rosalee (Bree Turner) finally tied the knot. However, the newly-weds' honeymoon may have to wait as the couple will try to help Nick find the cure for his current predicament.

Trubel will lend Nick a hand

Aside from Monroe and Rosalee, Trubel will also help Nick in finding a way to get back his Grimm powers. In the meantime, she will be Nick's "eyes and ears for the Wesen world."

Louise Lombard and Elizabeth Rodriguez will appear in the show

Two lovely actresses are signed to set foot in the mysterious neck of the woods. Louise Lombard and Elizabeth Rodriguez will appear as guests stars next season.
