Portland's resident "Grimm" was dealt a very bad hand at the end of season 4.

The last few minutes of Grimm's fourth season were intense. Nick Burkhardt (David Giuntoli) and Juliette Silverton (Bitsie Tulloch) had a confrontation that ended with the new hexenbiest about to kill her fiance. Luckily, Trubel (Jacqueline Toboni) arrived just in time to fire two arrows into her.

Juliette's demise, and his mother's death because of Juliette's betrayal, would definitely have a deep and lasting impact on Nick. How it changes him would be seen in the show's fifth season, at least that's what Grimm's executive producer David Greenwalt teases.

For one, Nick's career in law enforcement will be affected by the events of last season's finale, as will his relationship with Trubel. With her murder of Juliette and the reappearance of FBI Agent Chavez, rumors have surfaced that Nick will feel that Trubel betrayed him.

However, those are rumors that executive producer James Kouf quickly shot down. During an interview he gave for "TV Line", Kouf explained that Nick has "gotta know, being a Grimm, that she had no choice if he were to survive."

Another relationship rumor revolves around Nick and Adalind Schade, the hexenbiest (ex-hexenbiest?) who is carrying his baby. Some fans believe that the two will begin a relationship while others are adamant that this would not work.

But the way Greenwald sees it, "something's gotta happen, one way or the other."

"He's got a child and he's got to step up at some point," expounded Kouf. "He knows he can't abandon his child. He was abandoned."

However, everyone agrees that at one point Nick will have to deal with his losses and move forward. But it is a darker and more menacing Grimm who will emerge.

"It's not going to be the same 'Grimm,'" Greenwalt confided to The Hollywood Reporter. "I think it will be even bigger, even darker, even weirder."

"Grimm" will be back on air on October 2015 on NBC.
