Juliette will begin to embrace her inner hexenbiest, which may further jeopardize her relationship with Nick in Friday's all-new episode of "Grimm."

The next episode, titled "Heartbreaker," will present a new spin on the classic Frog Prince story with a much more tragic ending as Nick and Hank investigate the case of the week.

A sneak peek video reveals that Nick and Juliette's relationship will continue to tumble downhill when Juliette decides to move out of Nick's home and stops by to collect her stuff. In the clip, the couple has a tense conversation and Juliette completely blows Nick off after he tells her that he loves her.

"I haven't given up yet," Nick said to Juliette.

"Why not?" she replied.

"Because I love you," he answered, prompting the new Hexenbiest to laugh in his face.

"That's great. That's really great," she said.

That's when Nick's phone starts to ring and Juliette orders him to "Answer it," adding: "Come on Nick, there's a lot of big, scary Wesen on the loose in Portland. That's what you're good at. Go get 'em, Grimm."

During an interview with Zap2it, actor David Giuntoli hinted that Juliette will begin to become hostile towards Nick.

"Juliette is being mean to Nicky-roo," said Giuntoli, who plays Nick on the show. "I think her brain is weirded out. Becoming a Hexenbiest isn't something where you get a notice in the mail. Her brain is turning into something else. Part of her brain is human, part of it is growing a new lobe of evil and power. She's off. She's chemically off -- I'm just talking about Juliette, just to clarify."

Furthermore, TVLine confirmed that there will be a death in the Season 4 finale.
