"Grimm" Season 4 premieres Oct. 24 on NBC. Fans have to wait a long time again, but Sasha Roiz gives a bit of hope. His character Captain Sean Renard is probably not going anywhere despite contract issues in social media talks. Meanwhile, Nick Burkhardt (David Giuntoli) faces a new challenge in the show's fourth season.

Spoiler alert: This feature contains spoilers on Grimm Season 3 finale and earlier episodes. Read at your own risk.

Teresa "Trubel" Rubel (Jacqueline Toboni) fails to give Nick the potion that prevents a grim catastrophe - pun intended - at the end of Grimm Season 3 finale. Nick loses his special abilities, while Sean fights for his life.

Adalind Schade (Claire Coffee) is unstoppable until she gets her baby back. On the bright side, Rosalee (Bree Turner) and Monroe (Silas Weir Mitchell) are married. These are the closing changes in Grimm Season 3.

In Grimm Season 4, Nick is expected to recover his Grimm powers, even as Juliette (Bitsie Tulloch) seems relieved that he has lost it.

Sergeant Drew Wu (Reggie Lee) discovers one of Nick's Grimm books at his home, which means he could be angry at Nick for the way he acted in the show's "aswang" episode.

"I think [Sean getting badly injured] made for a good finale," Sasha Roiz tells Digital Spy in this interview. The actor added there could be "tremendous changes" to the captain's character if or when he returns in Grimm Season 4.

"I don't even know where all that contract gossip began," Roiz adds.

Talking about Adalind, Roiz says she might decide to reconcile with Renard after she discovers some "surprise" in Europe.

Still based on the same interview, it may be safe to say Trubel is coming back in Grimm Season 4.

Trubel is "remarkably strong, she just doesn't know what her mission is yet," this Entertainment Weekly report says.

Grimm Season 4 filming in Portland begins in July. Jacqueline Toboni announces on Twitter what she would do in the city.
