Portland buckles under the attack of the Black Claw in the upcoming episode of the hit NBC series "Grimm."

In "Key Move," TV Guide reports that the city will fall in disarray when the Wesens decides to make their move. The chaos will ensue when Nick (David Giuntoli) and Monroe (Silas Weir Mitchell) are overseas on a perilous quest. The pair is off chasing an enigma, "the source of a long-gestating mystery." It appears that they are close to uncovering the truth, as long as nothing bad and supernatural stops them from doing it. Will they finally get the answers they are looking for?

Meanwhile, the complicated triangle formed by Nick, Eve/Juliette (Bitsie Tulloch) and Adalind (Claire Coffee) continues to make things difficult for everyone involved. Adalind, in particular, is feeling the tension, especially when Eve decided to push herself back in Nick's life. Coffee shared in a recent interview with TV Guide that her character was not pleased that Nick's ex has returned as a powerful assassin for her former employer.

"[Adalind] definitely doesn't feel okay about Eve being back. She's very scared of Eve and she's every scared for what Eve being back means for her relationship with Nick," the actress explained about her character. "Even if Eve is changed, I don't think she really trusts that Eve is a totally different person and that it won't jeopardize her relationship with Nick," she added.

For Eve, the only thing she is concerned with is Nick's loyalty to Hadrian Wall. She thinks that Adalind will just jeopardize the Grimm's relationship with her saviors. She and Nick will be part of the anti-Wesen's group's huge assault against the enemy. Although she might not know it yet, Adalind will also be "swept into the war" soon. Her involvement will reportedly affect her storyline in a major way.

"Grimm" season 5 airs Fridays at 9 p.m. EST on NBC.
