At a carnival, a ringmaster named Hedig (Carlo Rota) is presenting to the public four Wesen that act as freaks, taking the excuse of magic.
Wu (Reggie Lee) is finally in service after leaving the psychiatric hospital and Nick and Hank (Russell Hornsby) investigate the murder of the two girls, finding their tickets to the carnival.
Back in Europe, Adalind (Claire Coffee) and Meisner (Damien Puckler) continue fleeing from the Verrat and find Sebastien (Christian Lagadec) in a car, badly hurt.
While Nick and Hank talk with Hedig, Max loses control of himself and attacks one of the performers, Genvieve (Chryssie Whitehead).
And when that leaves room for Monrosalee to take charge, it's usually an issue of Wesen rights that serves as a mild allegory for disenfranchised or mistreated persons.
"[4] Nick McHatton from TV Fanatic, gave a 3.8 star rating out of 5, stating: "The carnival lends itself well to Grimm's world because it answers one of the questions of Wesen woguing for money in a safe space.
"[5] MaryAnn Sleasman from TV.com, wrote, "Sam Witwer and a Wesen carnival and Monrosalee wedding planning and twisted, cheeky use of Warren Zevon's 'Werewolves of London' — this episode of Grimm made me so happy, you guys.
It didn't even really move the plot very far: Adalind is still running around in the woods, the circus storyline (though refreshingly different from the usual gloomy murder investigations) was wrapped up all neat and pretty, and as much as I want to doodle little hearts around Sam Witwer's face every time it appears on el television, I'm concerned about how Max the Blutbad was basically just a hairier version of Being Human's Aidan the Vampire.
