'Grimm' Season 6 Air Date, News & Update: Adalind A Prisoner? Eve To Help Nick's Girlfriend? 'Castle' Actor To Join Scooby Gang?

"Grimm" Season 6 continues from S5 shockers with Adalind Schade (Claire Coffee) a Black Claw prisoner while Juliette Silverton (Bitsie Tulloch) as Eve could be persuaded rescue the girlfriend of Nick Burkhardt (David Giuntoli). As the Scooby gang grapple with fallout from Black Claw and consequences from the magic stick in "Grimm" Season 6, Adalind Schade and Sean Renard (Sasha Roiz) will have a tug-of-war with daughter Diana (Hanna R Loyd).

In an interview with TVLine, the "Grimm" Season 6 cast discussed the series return after Diana accidentally saved Nick Burkhardt while the Black Claw leader and Sean Renard teamed up. No happy-ever-after just yet for Nick Burkhardt and Adalind Schade as the rival of Juliette Silverton remains a prisoner of the enchanted ring forced on her by the Black Claw leader in "Grimm" Season 5.

  Sean Renard, bent on fulfilling Black Claw vision of Wesen rule as Portland Mayor, will likely continue to keep Adalind Schade a prisoner in "Grimm" Season 6 using the ring, Kelly and Diana. Claire Coffee revealed that Adalind Schade will struggle to guide her daughter Diana toward goodness but "Grimm" Season 6 villain Sean Renard may oppose.

"Grimm" Season 6 may, in fact, be a battle to influence Diana since seeing Adalind Schade shun her Hexenbiest side, Sean Renard will not want his daughter to subdue her Wesen powers for the sake of humans. Juliette Silverton, whose Hadrian Wall team was destroyed in "Grimm" Season 5 with Meisner murdered, would still be Eve according to Bitsie Tulloch.

Given that, Juliette Silverton as Eve could continue the Hadrian's Wall mission with Trubel (Jacqueline Toboni) in "Grimm" Season 6 and rescue Adalind Schade. Juliette Silverton, full of guilt from her deeds as a Hexenbiest and as Eve (seen in the "Grimm" Season 5 finale), would essentially help the girlfriend of Nick Burkhardt to save Diana and Kelly from Sean Renard.

TVLine further reports that Nick Burkhardt, Hank (Russell Hornsby) and Sgt Wu (Reggie Lee) will be joined by "Castle" actor Chris McKenna as Lieutenant Grossante in "Grimm" Season 6. Do you believe Sean Renard is the ultimate villain in "Grimm" Season 6 or should Nick Burkhardt, Adalind Schade and Juliette Silverton look out for an even bigger villain?
