More drama and horror await fans when "Grimm" returns for season 6 this fall.

In the two-hour season 3 finale, Nick (David Giuntoli) managed to get rid of Black Claw with the help of his friends. But this means that the feud between him and Renard (Sasha Roiz) will intensify next season since Adalind (Claire Coffee) and their son Kelly are still being kept by the police captain-turned-politician.

Aside from the situation with Renard and Adalind, Nick must also face the fact that Eve's (Bitsie Tulloch) feelings as Juliette have finally returned with the help of the miracle stick. This could mean that he could possibly be in the middle of a love triangle between his girlfriend and the mother of his child.

Lead star Giuntoli teased the possible scenarios that could happen between Nick, Eve, and Adalind.

"I think there's going to have to be a major come-to-Jesus moment, or a dozen of those," the actor told TVLine. "Because she did so many terrible things to me and my family, but you have to remember: Juliette did all of these things under the influence of a power that happened to her as a side effect of something she was doing to try to help me. How did it happen? She turned into Adalind, and it was for the benefit of Nick."

Aside from the complicated love story that will unfold around Nick next season, his friend Monroe (Silas Weir Mitchell) will have a happier arc next season as he and Rosalee (Bree Turner) await the birth of their first child together.

"Grimm" season 6 will return on NBC this fall. It may have a shorter run after the network announced that the initial order for the upcoming season is for 13 episodes instead on the usual 22. But the network could still increase the number of episodes for season 6 depending on the reception of the audience for the next season.
