“Turn back, turn back, thou pretty bride, within this house thou must not abide. For here do evil things betide”
The big day has finally come on the latest episode of Grimm Season 3: Monroe and Rosalee will finally say “yes”.
Nick will have to wear sunglasses so that the many wesen attending the wedding won’t understand he’s a Grimm.
Adalind-turned-into-Juliette goes to see Renard. She kisses him, and tells him she still has feelings for him.
As soon as she’s back to be Adalind, she calls the real Juliette, to tell her that Renard’s obsession with her may have returned, and that she might help her with a potion. Juliette refuses, and tells Nick about it.
The next day, Renard calls JUliette to tell her that he’s fond of her, but that they can’t be together ever again.
Nick and Trubel move Nick’s trailer to a safer place. They hide it in the woods, where Nick has bought a piece of land.
Adalind calls Juliette again, and she tells her Renard called. So Adalind says that she may have something that will make him stop.
Juliette tells her that she has to take care of that.
In the meantime, Renard discovers the storage that belonged to Adalind’s mother, and starts to understand what’s going on.
Adalind-turned-into-Juliette meets Nick at home, and they spend a romantic night together…
Trubel sees her while she’s leaving the house, and she feels something’s off with that Juliette, so she decides to follow her, and she sees her taking a cab. A few seconds after, Adalind has come back to look like Adalind.
When she comes back, Trubel sees Nick leaving for Monroe and Rosalee’s wedding with the real Juliette.
While driving to the wedding, Nick and Juliette realize what happened…
Renard goes to Nick’s house to talk to him, but he finds Trubel. She tells him what she saw. Renard says that he has to find Nick immediately, or something very bad is going to happen to him. He has to make him drink a sort of potion. Trubel gives Renard the address of Monroe and Rosalee’s wedding, but as Renard runs out the house, he gets shot by Steward, the FBI agent who wanted to kill him and Adalind.
He tries to kill Trubel too, but she kills him first, he was a wesen.
Trubel calls help for Renard, takes the potion and Renard’s car keys and runs to find Nick.
And in the meantime, the wedding is happening… Rosalee looks gorgeous in her dress.
Wu and other police agents take care of Renard. They find the dead body of Steward. Wu goes into Trubel’s room, and he finds the books belonging to Nick, with images of wesen inside.
Adalind leaves Portland, while we still don’t know if Renard is going to live.
Monroe and Rosalee are finally husband and wife.
But, a few seconds after, Trubel rushes inside the room, looking for Nick. Unfortunately, she’s not wearing sunglasses, so all the wesen in the room recognize the Grimm in her.
Trubel tries to make Nick drink the potion, but the bottle falls and breaks. Right after, Monroe realizes that Nick is not a Grimm anymore… That’s when they realize that’s what Adalind did. She took Nick’s powers away.
Nick, Hank, Juliette and Trubel run away before all the wesen invited at the wedding can find them again.
What’s going to happen now that Nick is not a Grimm anymore?
Grimm will be back with Season 4 in the Fall.
