Grimm Season 4, which premieres this Friday, 24th October, on NBC, will find Detective Nick Burkhardt (David Giuntoli) learning to cope with the unexpected loss of his Grimm abilities. Besides, the arrival in Portland of a new Wesen, who steals its victim's memories, creates a lot of tension in the city.

David Giuntoli previewed Nick's journey in the upcoming season, and talked about how he is going to be handling the fact that he is no longer a Grimm.

Giuntoli told Collider: "Grimm powers are gone from Nick, and he's enjoying his new normalcy, in a lot of ways, but he also knows that the Wesen are out there. So first and foremost, he's going to be using Trubel as his seeing eye Grimm.

"He is going to be tapping on Monroe's shoulder quite a bit. He's going to be using his team of Wesen and Grimms to try to do what he used to be able to do. But he doesn't have his powers anymore, and that means that not only can he not see the Wesen, he's just not as powerful as he was."

The 34-year-old actor also revealed that his character will focus on being a cop again.

"He used to solve crimes without having blatant tells as to who did this. So now, he has to remember that he was a good detective and start solving cases the old-fashioned way, through evidence."

In the last season, Adalind got Nick to sleep with her by posing as Juliette, and this incident will definitely be addressed this season.

"The Nick and Adalind spell links us in a very profound and mysterious way. Something goes down, in order to reverse a spell that she has put on me, that is just crazy. It affects Juliette and I, in a very intense way."
