The episode was written by Sean Calder from a story by Thomas Ian Griffith and Rob Wright, and was directed by Clark Mathis.
The rest of the girls meet up at a warehouse with a smarmy, controlling guy named Ken (Michael Graziadei) who inspects the merchandise disapprovingly.
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.
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.
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".
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.
Club's Kevin McFarland gave the episode a "B−" grade and wrote, "By introducing a completely new character that threw a wrench in every bit of the tenuous equilibrium Grimm built within the New Scoobies, there was hope for the show to jolt in a new, unexpected direction.
"[5] MaryAnn Sleasman from TV.com, wrote, "If there'd been any doubt that Nick was attempting to tackle more than he could handle in adopting the latest stray to wander into Portland, 'My Fair Wesen' drove the point home with a series of mishaps courtesy of Trubel the Reluctant Grimm that kind of made me wonder how she's survived until now.
