Grimm finale: David Giuntoli teases miracle stick repercussions

Grimm’s fifth season comes to a close Friday with a special two-hour finale episode. With Nick’s anger boiling over after seeing Renard with Kelly and Adalind on television, the battle against Black Claw is about to be set in motion.

We chatted with David Giuntoli, who plays Nick, about the unexpected relationship between Nick and Adalind, the miracle stick, and what kind of trouble the season finale may bring for our Scooby gang.

ENTERTAINMENT WEEKLY: How would you explain Nick being so calm and trusting of Adalind when he knew she wasn’t being honest about her powers returning?

DAVID GIUNTOLI: I mean, I had a choice to play it two different ways really. On the page, he was a little more understanding. Listen, Adalind and Nick are two people in a very kind of similar situation. We’ve been painted into a very precarious corner based upon our respective heritages. She was born a hexenbiest; I was born a grimm. We accidentally had this baby together, and she lost her powers. One of the things that Grimm is about, one of the themes, is there is something that lurks inside that is not our fault, and there’s a war between the evil inside of you and the part of you that’s trying to keep that evil at bay. When [Adalind] lost her hexenbiest powers, she never wanted them back, and if they come back, it’s not her own fault. I think she and Nick are in a similar situation with raising a child together, so there is empathy. There’s a lot of empathy there.

Nick’s line to Eve in the last episode about Kelly not being her child was pretty harsh. Do you think he still holds a lot of anger toward Eve, even though she’s not technically Juliette?

I think there is a lot of anger toward Eve. I think it would be a little more nuanced if Nick thought Juliette was anywhere in there. And I think sometimes he takes that anger out on Eve.

We’ve been seeing little bits of Juliette shine through in Eve when it comes to protecting Nick. If Eve regained some of her old self, would she and Nick ever be able to reconcile, either as friends or romantically?

If Juliette were to come back, it would be a very complicated situation. [Nick] would have to ask all of these questions. Like the things that Juliette and Eve have done, especially when she was under this spell of being a hexenbiest — this evil thing that kind of took her over, that was like a poltergeist, like the exorcist — who’s to blame? Is it Juliette? Does Juliette know what she did? Who’s calling the shots, and who’s at the steering wheel? So all of that kind of stuff would have to be sorted through, but I think Nick is capable of forgiveness in this situation. Because again, remember, she turned into this hexenbiest, she was taken over by this hexenbiest, because she was trying to help Nick.

Let’s talk about the miracle stick. Nick showing Trubel where it was in the last episode seemed pretty foreboding. Is it safe to say that we’ll be seeing it come into play in the season finale?

Oh, yeah. That little stick is a major player. Tiny stick, big world. The writers of Grimm don’t just willy-nilly throw in a stick for no reason. It’s clearly going to have some major repercussions. And the Scooby gang, helmed by Nick, are learning about its powers as the viewers are.

Please tell us that we get to see Nick go full-on grimm and kick a lot of Black Claw ass in the finale.

Nick looks cute with that baby, but look, the season finale is going to be a very lovely opportunity for Nick Burkhardt to go full grimm on the city of Portland and Black Claw. Grimm Unchained.

How much of a threat is Diana? We’ve seen her recently pushing for Renard and Adalind to be together. Should Nick be worried about his safety if he breaks up Diana’s happy family?

Imagine if you, at the age of 5 or 6, had all of the power in the world — if your 5-year-old whims were backed by supernatural powers beyond compare — that’s what Diana is. And yeah, she is a threat. It’s not like she’s evil, but she has no understanding of her power and doesn’t know how to handle her emotions and has too many tools behind them. She’s kind of like a domesticated bear — generally tame, but you never know when s— is going to hit the fan.

The Grimm finale airs Friday at 8 p.m. ET on NBC.
