Tonight's episode of “Grimm” finishes up the two-part season premiere and Nick (David Giuntoli) fans may have to prepare themselves for disappointment—not in the episode, but in their favorite character.

According to TVLine.com, Nick is going to do something in Zombie mode that will haunt him going forward.

In an interview with the website, Giuntoli says his character will face issues with how his friends respond to this unspeakable act.

He adds that the deed will provide “tremendous conflict and guilt” for Nick. Giuntoli adds it “destroys Nick, mentally and emotionally.”

At the end of last week’s episode Nick was staring at a small family with his scary Zombie eyes. This forshadowed really bad things for the family.

According to NBC.com, Nick unfortunately goes after that family. In a sneak peek provided on the website the mom is trying to hide in a closet with her two daughters as Zombie Nick is attempting to beat down a door to get the father of the family.

Fortunately Monroe and Hank get to the house in time. As their trying to take down Nick and keep him from killing the family, Hank utters a statement that would probably win him the Captain Obvious award. You know, if there was one.

“We gotta stop him,” he tells Monroe. Duh. Monroe’s response? “That’s what I’m tryna do”. The sneak peek ends with the dad attempting to do something that was probably a better idea in his head. You can watch below.

“Grimm” airs Fridays at 9/8c on NBC.
