There will be new surprises, guest stars and possibly, a major death in Season 4 of "Grimm."

The NBC fictional drama is currently on hiatus and not scheduled to return until March 20. However, new reports from TVLine suggestions that the series is mulling about going "really, really dark" and killing off a major character in the show.

In other news, "Grimm" is currently looking to cast someone to play the guest-starring role of "Iron Hans," a rugged 50-something-year-old ranch owner who helps Wesen fathers and sons reconnect with their warrior heritage through his weekend retreats. He also has a beautiful and strong-minded 20-something-year-old daughter named Maggie, notes TVLine.

As fans may recall, in the last episode of "Grimm," Adalind and Juliette got into a full-blown brawl, reports Entertainment Weekly. However, because Juliette has been transformed into a Hexenbiest, she was much stronger than Adalind and gave her a major beat down.

Following their match-off, Nick came home to discover his house in total shambles. When he asked Juliette what happened, she confessed that she had gotten into a fight with Adalind and that she almost killed her because she has become a Hexenbiest. She then decided to woge in front of him, leaving him in complete and utter shock, reports Oregon Live.

The next episode, which is entitled "Bad Luck," will pick up where the storyline left off on March 20. According to The Hollywood Hills, the official teaser synopsis for Episode 14 reads as follows:

"His beauty has become a beast and Nick will be determined to find answers. But one more visitor is in for a big surprise."

A promo video also reveals that Henrietta will tell Nick that there is no cure for Juliette's condition. Henrietta also tells Adalind that she is expecting, which could mean that she is pregnant with Nick's baby.

"Grimm" Season 4, Episode 14, "Bad Luck," airs on Friday, March 20 at 9 p.m. EST on NBC.
