Along with talks about a new villain, "Grimm" season 6 is set to bring back Juliette.

Juliette is set to return in "Grimm" season 6, according to series co-creator David Greenwalt. In his interview with TV Line, Greenwalt said that he thought there was going to have to be a major "come-to-Jesus" moment or a dozen of those, adding that she had done all those terrible things under the influence of a power that had taken place to her as a side effect of something she had been doing to try to help him.

While Juliette is set to come back in "Grimm" season 6, it is revealed that the character will not set up a Juliette-Adalind-Nick love triangle. In her interview with Collider, Bitsie Tulloch, who plays Juliette in the series, said that there was no love triangle for the time being, but she would be shocked if they did not play with it because most of her comments on social media had been about Nick and Eve going to get together.

Along with fans seeing Juliette's return, fans are also set to see a new villain in "Grimm" season 6. In his interview with Entertainment Weekly, David Guintoli, who plays Nick in the series, was asked on whether fans could see Black Claw in the sixth season. The actor replied that the group was so done and they were not going to come for his character again, adding that he had killed like 30 people that tried to get him.

"Now, it's Renard versus Nick. I think," he said. This means that Renard could be the new villain Nick faces in "Grimm's" season 6.

For the time being, the exact release date for "Grimm" season 6 is yet to be revealed.
