Watched "Blond Ambition" and "Deleted Scenes" from Grimm.

Rehearsals for Monroe and Rosalee's wedding are followed by a dinner at Monroe's house.

Adelind morphs into Juliette's doppelganger, visits Captain Renard, and kisses him. Later, Captain Renard calls Juliette and tells her that they should not be having an affair. Juliette--the real one--doesn't know what he's talking about. Later, Captain Renard goes to the warehouse where Adelind's mother's effects are stored. He comes upon the cauldron and the book from which Adelind concocted spells, and takes some of the potion in a bottle.

Nick and Trubel move Aunt Marie's trailer to a piece of land inside a forest where the trailer will be harder to find.

Adelind as Juliette's doppelganger next visits Nick and seduces him. They make love before going to Monroe and Rosalee's wedding. Their conversation en route to the wedding leads them to conclude that Adelind came to Nick as Juliette's doppelganger.

Captain Renard drives to Nick's house, where Trubel informs him that Nick and Juliette are at a wedding. Captain Renard asks where the wedding ceremony is being held. He discloses to Trubel that Nick must drink the potion in the bottle as an antidote to Adelind's spell. As Captain Renard exits, however, the Verrat agent who has been stalking him shoots him several times, and then chases Trubel upstairs. He woges, and Trubel beheads him with her machete.

Trubel calls the police, retrieves the wedding address and the potion bottle from Captain Renard's pocket, and drives to where the wedding is being held. Since she is a Grimm, the wedding entourage and guests all woge, and there is mayhem. The potion bottle falls to the floor and shatters.

Nick and company discover that, due to Adelind's spell, Nick is no longer a Grimm. He was unable to see the Wesens woging, and cannot see Monroe and Rosalee woging for him. "You're not a Grimm anymore" was Monroe's famous line when this episode was broadcast.

Sergeant Wu and the police team rush Captain Renard to hospital.

In the last scene, we see Adelind in a plane bound for Germany.
