Through the remainder of Grimm season 3, Nick (David Giuntoli) might become more Wesen-like in his behavior.

Giuntoli recently spoke to BuddyTV, discussing Nick's evolution over the course of season 3 and how being a zombie in the first few episodes will affect the rest of the season.

"We're going to be playing on this one for a little while," Giuntoli teased when asked if the zombie side effects would persist through season 3. "It's funny, every time Nick gets harmed, he's left with this kind of useful side-effect and we're going to definitely be seeing more of that after the break."

Giuntoli also warned that the longer Nick is in his position as a Grimm, the more likely he is to turn to the world of the Wesen.

"I sense that it happens, and I'll become more and more to the world of Wesen," he said. "And [Nick's] not afraid of people anymore, so that's a good sign for my character, getting dark." He also noted that Nick is not in control of his newfound powers, such as super-hearing and the ability to survive death, so they could either end up helping him or hurting him.

In other Grimm spoiler news, executive producer David Greenwalt teased a few more details about what to expect from Nick in the second half of season 3.

According to the EP, Nick will have to "go from being the student to being the teacher. He'll be passing on some of the information he's learned - but we can't tell you to whom."

Grimm season 3 airs Fridays at 9 p.m. on NBC.
