Fans of NBC's "Grimm" can expect the next all-new episode to be intense now that Nick knows that Juliette is a Hexenbiest and Adalind may be pregnant with his child.

In last week's episode, "Trial By Fire," Adalind showed up at Juliette's doorstep unannounced while Nick was gone. She then left herself in and confronted Juliette about her role in taking away her daughter, Diana, who is now being raised by Nick's mother. She also took a jab at Juliette by rubbing in the fact that she slept with her boyfriend, Nick. Eventually, this led to a full-blown and much overdue brawl between the two witches after Adalind threatened Juliette, notes Entertainment Weekly.

However, Adalind's powers proved to be no match for Juliette, now that she has been transformed into a Hexenbiest. As a result, she ended up running away from Juliette's home after suffering from a 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.

"There's something I have to show you. You know how much I love you," Juliette told him before showing him her beastly side.

The next episode, "Bad Luck," will pick up where last week's storyline left off. A promo video reveals that Henrietta will tell Nick that there is no cure for Juliette unless he kills her. Henrietta also tells Adalind that she is expecting another baby, which could mean that she is pregnant with Nick's baby.

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