There is a lot of talk surrounding the sixth season of NBC's "Grimm." The upcoming season is said to have new villains, but they will be played by old faces. While it is widely known that Renard (Sasha Roiz) may be the new big bad in season 6, there is also some speculation that Adalind (Claire Coffee) might become evil.

According to reports, Nick may unwittingly make Adalind evil when he uses the magic stick to help her. Adalind is currently with Renard because of their daughter, Diana, but Nick (David Giuntoli) will come to her rescue. However, rumor has it that things won't exactly end the way he expected as a side effect of utilizing the magic stick may mean an evil Adalind.

Nick wants to save Adalind and Diana from Renard's clutches because the latter is hatching up an evil scheme. And while the power of the magic stick is great, using it may lead to a whole other issue. Adalind's Hexenbiest is still being contained at the moment, but the magic stick could change all that.

While the notion of Adalind turning evil is still unconfirmed, Renard's descent into darkness is a sure go. "People are always suspicious of him, as they should be. I don't think even Nick or the group ever really trusted him, and now they really have reason to distrust him. Yeah, it's a full-out war at this point and that's really enjoyable for me," Roiz told Showbiz Junkies in an interview.

However, there are some fans who like Renard and want him to become a good wesen. Roiz admitted that he has only read the first three episodes of the season, which means there is still room for his character to have a change of heart. But if given the option, Roiz would want Renard to go "in a blaze of glory."

"Grimm" season 6 has yet to be given a premiere date.
