Grimm Season 4 Wikipedia

Nick (David Giuntoli) and Hank (Russell Hornsby) tackles a tragic "Frog Prince" inspired case in the upcoming episode of "Grimm" Season 4.

The upcoming episode of Grimm Season 4 is dubbed as "Heartbreaker," and it deals with a homicide case involving a cyclists. In the middle of the investigation, the crime fighting duo met a Wesen who possesses the power of a terrible fatal touch.

The case could be very difficult to handle, since both police officers know that it is very hard to deal with a Wesen. This is why learning about a Wesen with a dangerous magic could be too difficult for them to handle.

On the other hand, Captain Renard (Sasha Roiz) and Adalind (Claire Coffee) discovers that the royals have increased their measures to find their child. Another royal family member, portrayed by guest star Nico Evers-Swindell, will be introduced during the episode as well.

But the main drama of the episode revolves around Nick and Juliette (Bitsie Tulloch), who must come to terms with her inner struggle as a hexenbiest.

Juliette's transformation will make her more conscious about her personality, which could make her meaner to Nick.

In an interview with Zap2it, Giuntoli teased that Juliette will start to be more hot headed towards his character Nick. The actor believes that Juliette's transformation is doing something in her brain that could also change her personality.

However, Juliette's transformation is the not only problem of the couple.

Actress Claire Coffee dropped a bomb during her interview with TVLine. According to her, Adalind will find out that she is pregnant, and the father of the child is Nick.

"She knows it's Nick, but publically, I think she's trying to figure out which father will benefit her the most," she said.

Will Nick and Juliette's relationships survive these hurdles?

'Grimm' season 4 episode 16 airs Friday, April 3.
