Juliette Silverton (Bitsie Tulloch) is set to return in "Grimm" Season 6. But will her return change things for ex-boyfriend Nick Nurkhardt (David Giuntoli) and Adalind (Claire Coffee)? 

Nick finally saw a glimpse of his ex-girlfriend when he used the Stick to heal Eve in the "Grimm" Season 5 finale. However, the episode ended with Nick defeating Conrad Bonaparte (Shaun Toub) in an unexpected way. Adalind's daughter Diana decided to control Sean Renard (Sasha Roiz) to stab Bonaparte with a sword, says a report by Movie News Guide.

Nick and Renard were also reportedly seen in the last moments of the "Grimm" Season 5 finale, surprising viewers of the encounter. 

David Giuntoli had told TV Insider that Nick's role is complicated, and that he is confused about the new situation. "It's all too much for Nick to take in. It certainly sounds like the possibility will be explored in Season 6."

Referring to the show's season 5 finale, Guintoli said: "We have time to wrap it up in a wonderful, perfect way, for all of our characters. We will go out big and we will go out strong."

Giuntoli had hinted of the return of Bitsie Tulloch's Juliette on the show's sixth season. Also with the Stick still around, viewers can likely guess for Eve to turn back into Juliette. Her return could give an interesting twist to Nick's already complicated life.

But could Juliette really change Nick's feelings for Adalind? Will she remain the cruel Eve as in the fifth season? 

According to another report by TV Insider, the series has been renewed for a 13-episodic run for its sixth season.

"Grimm" officially returns with Season 6 this fall on NBC.
