My Fair Wesen

Opening quote: "No longer a dark, gray bird, ugly and disagreeable to look at, but a graceful and beautiful swan."

Trubel (Jacqueline Toboni) is introduced to Juliette (Bitsie Tulloch) as yet another Grimm, much to her surprise and Nick (David Giuntoli) states that she will live with them for a short time in order to introduce her to the Wesen world.

In an upscale store, a group of women distract the clerks so they can steal clothes & jewelry. One of them, Cammy (Kiah Stern) almost gets caught then fails to meet them at their rendezvous point. The rest of the girls meet up at a warehouse with a smarmy, controlling guy named Ken (Michael Graziadei) who inspects the merchandise disapprovingly. Cammy eventually shows up there in a panic but Ken is upset at Cammy's late arrival (& for getting detected stealing previously), woges into a Lebensauger and kills her by sucking her blood dry, as the other three cower in silence.

Renard (Sasha Roiz) places Adalind (Claire Coffee) in a hotel suite for safety and at her plea, he decides to stay with her overnight.

Not feeling well with all the Wesen revelation and strange hospitality, Trubel decides to quietly leave, only to be stopped by Nick out on the porch, having anticipated her reaction. He claims that if she doesn't give his help a chance and runs off again, she could land up in jail for the murders she committed. This convinces her to stay and she returns to bed. Next morning he introduces Monroe (Silas Weir Mitchell) and Rosalee (Bree Turner) and gets them to proper woge to her to prove that she doesn't need to be afraid of every Wesen.

A couple discover Cammy's body in the woods. Nick and Hank (Russell Hornsby) go to investigate and decide to bring Trubel as a ride-along. Upon seeing the drained blood, distinctive bite mark and no razor used on the body, they decide to look for info/clues at the trailer. There, Hank finds that the characteristics belong to the Lebensauger and Nick remembers Ryan's case, a Wesen they've encountered before. They decide to check the last place where Cammy stayed but before leaving Trubel also finds an entry on a Siegbarste, a Wesen whom she claims killed her foster parents.

Meanwhile, Ken tells one of the girls, Donna (Karissa Lee Staples) to find a replacement for Cammy so as to complete "their little family".

Nick, Hank and Trubel arrive at the house where the owner introduces them to Megan (Mavil Avila), Cammy's roommate. Frustrated that Nick & Hank got no information, while later alone with her, Trubel threatens Megan, who's a Wesen, to reveal anything she knows about Cammy's whereabouts. Megan reveals that Cammy last saw Donna in a square downtown. They discuss with Renard that Donna may be looking for a replacement girl/thief. Meanwhile, Trubel talks with Wu (Reggie Lee) about not being comfortable with all the new experiences, causing him to remember the nightmares he experienced.

Adalind arrives at a storage unit to retrieve something that her mom left in her will and finds a book of spells, although the book won't open, seemingly magically sealed shut. In frustration she throws it through a mirror and accidentally cuts herself with a shard of glass but her blood drips on the book, sizzling and absorbed by the pages, that proves to be the key - causing it to open.

Nick, Hank and Trubel are watching over Donna but Trubel, in an attempt to solve the crime, rushes over to her feigning being a runaway beggar and successfully acquiring her attention then leaves with her. Donna takes Trubel to the girls and with Ken, who approves of her and tells them to give her a dress and makeover. Nick and Hank manage to trace down Donna's vehicle and arrive at the warehouse. Meanwhile, Ken has been attempting to have sex with Trubel, causing her to snap at him via a punch to the nose, which causes him to woge into his Wesen form. He is outraged that he's been brought a Grimm and pounces on her. Donna woges into another Lebensauger and tries to ambush her too, just as Hank drives the car into and through a wall, giving Trubel time to stab Donna in the neck. Ken tries to attack before Nick kills him with a few bullets to the torso. The other two cowering girls are rescued.

Later that night, Trubel tells Nick and Juliette that she knew she had stuffed up and that she would like to stay a bit longer to learn more. As the lights elsewhere in the house are turned out, Trubel is in bed, making notes about Lebensäuger in her book.

The final scene shows an elderly man coughing and holding one of the keys.
