7 Grimm Finale Tidbits: The Wedding, Double Juliettes, Trubel and More Chaos on the Way

Grimm Season 3 Finale Preview Dearly beloved, we’ve gathered here today to dish about Grimm‘s Season 3 finale, in which Rosalee and Monroe’s long-talked-about wedding finally takes place.

Even though the NBC drama is a series about fairy-tale monsters, how likely is it that everything will end with happily ever after? (We wouldn’t bet the honeymoon fund on it.) So while we won’t spill all the rice beans ahead of time — where’s the fun in that? — TVLine does have a few wedding presents we can offer up in advance of Friday’s airing (NBC, 9/8c).

Even better: Stars/groomsmen David Giuntoli and Russell Hornsby chime in with scoop on the chaos-filled episode, as well as what the series’ fourth season may bring. Read on for the matrimonial details.

A DIFFERENT DRESS (THANK GOODNESS) | If you weren’t a fan of the long-sleeved gown Rosalee previewed in a previous episode, you’ll be very happy with what she eventually wears on her big day — and the plot twist that makes the switch possible.

‘I DO’ DOES HAPPEN | Lest you worry that the Blutbad-Fuchsbau ceremony is interrupted before their union becomes official, allow Giuntoli to soothe your fears… kinda. The clock enthusiast and the spice-shop proprietress “actually get married, and then it doesn’t take but seconds — maybe not even a second — for everything to go wrong,” he tells TVLine. “All hell beaks loose. It gets crazy quickly. Let’s just say, we lose the crowd.”

A HAIRY AFFAIR? | The happy couple wear sport their human faces — all the better to see their huge smiles! — as they tie the knot. “And then they howl at the moon,” Hornsby jokes.

SHADY BUSINESS | Yes, Nick wears sunglasses (which hide his Grimm identity from the various Wesen in attendance) throughout the event. No, it does not prevent the insanity Giuntoli hints at above.

ADALIND’S REVENGE | The Hexenbiest’s new parlor trick of morphing into Juliette gets a workout in the episode, causing trouble that will likely extend into the following season. We can tell you that two characters are quick to realize what the disgruntled mama is up to, and one of them ends the episode in a very bad way.

TIME TO MOVE | Nick and Juliette’s home is once again the spot of unspeakable horror, something that the show acknowledges with a funny aside from a member of the Portland Police Department.

TRUBEL-ING NEWS | Nick’s Grimm padawan comes in quite handy in the finale’s final act, which makes us wonder whether Season 4 will bring more Wesen-fighters to town. “What I think we’re going to start dealing with more are the keys, the royals and this thing that the keys lead to,” Giuntoli previews. “I don’t know if we’re going to meet more Grimms, though. We have Trubel, and she’s a Grimm — so what more do you want?”
