The relief on Trubel's face (recurring guest star Jacqueline Toboni) when Nick (David Giuntoli) came back with his powers back in full force was so intense that tears burst out as soon Nick hugged her.

"You're not alone anymore," Nick assured her. For once, the young Grimm didn't have to hold up a strong facade. She was finally able to feel vulnerable now that she wasn't the only Grimm in town.

According to Carter Matt's synopsis, she will be making a very big decision in this Friday's episode, "The Grimm That Stole Christmas." Apparently, Trubel will come "to a life changing realization that will affect everyone."

Just what would this epiphany be?

In earlier episodes, she was kidnapped by FBI Agent Chavez who also turned out to be a Wesen. She was also a member of a secret society that apparently would like to get Trubel in for her "services."

Will she finally decide to join the mysterious group now that Nick is a Grimm again? Or perhaps she finally realized that she wants to stay with Nick and Juliette (Bitsie Trulloch) for good.

Meanwhile, with Nick's powers back in somewhat full force, he and Hank (Russell Hornsby) will investigate a very strange string of home invasion cases that will reportedly "lead to an even stranger Wesen phenomena."

Based on the "Grimm" season 4 episode 7 teaser video and sneak peek photos, our favorite Grimm will be dealing with some Gremlin-like creatures.

Monroe (Silas Weir Mitchell) and Rosalee (Bree Turner) will be celebrating their first Christmas together as a married couple. According to the synopsis, Monroe is planning a "very special Christmas surprise" for his new wife, despite the threats that they have been getting lately.

What do you think will happen this Friday? What do you think is Trubel's realization and how will the gang accept it? Watch the newest "Grimm" season 4 instalment this Friday, 9 p.m., on NBC.
