Season 5 Episode 6
When Nick and the gang are ambushed while investigating Wesen gang violence, a mysterious figure comes to their aid.
Nick (David Giuntoli) and Hank (Russell Hornsby) are on the case when a gang of Wesen vandalizes stores and kidnaps a Wesen bakery owner named Xavier. After consulting with Monroe (Silas Weir Mitchell), Rosalee (Bree Turner) and Bud, the group realizes Occultatum Libera is at work again, and Monroe and Rosalee shed light on how Wesen have routinely been the cause of street riots throughout history. Meanwhile, inside the bakery, Wu (Reggie Lee) discovers the four claw marks symbol - and Xavier.
Having escaped his captors, Xavier points out a woman, Billie, who was involved with his abduction. After being threatened by Nick, acting as a Grimm and not a cop, Billie agrees to lead Nick, Hank, Monroe, Wu and Renard (Sasha Roiz) to the Wesen gang's location. But when they arrive, they quickly realize it's a setup and that the gang was expecting them. Backed into a room, defeat seems unavoidable for the gang, until mysteriously, their attackers back off.
When Nick ventures outside the room, he sees the gang members lying on the floor, beaten or dead. A straggling survivor attacks him, but is quickly dispensed with by a mysterious force. When Nick gets a look at his rescuer, he is shocked to see... Juliette!
