Spoiler alert: This update contains “Grimm” Season 4 spoilers. Read on at your own risk if you have not watched Grimm 4x10.

Nick (David Giuntoli), Hank (Russell Hornsby), Wu (Reggie Lee), and Captain Renard (Sasha Roiz) hunt the Wesenrein in “Grimm” Season 4, Episode 10. Rosalee (Bree Turner) and Juliette (Bitsie Tulloch) both join the hunt, armed and ready. It turns out, however, that as a Hexenbiest, Juliette needs no guns.

Juliette reveals her new Hexenbiest self to Renard. In a Grimm 4x11 promo video, Renard asks her how this happened. The episode for the next episode mentions Renard is seeking help, but it is not clear if this is for Juliette.

“Captain Renard seeks assistance from a mystical woman from his past; at the same time, Nick and Hank investigate a shocking homicide at an abandoned residence that is allegedly haunted, leading many locals to believe a ghost is the culprit,” reads the episode synopsis of “Grimm” Season 4, Episode 11.

Juliette’s transformation is believed to be a side effect of the counter-ritual that Renard’s mother has fixed to help Nick become a Grimm again. In the Grimm 4x11 promo video, Nick wields a double-axe while walking to a sleeping Juliette. Is it a nightmare, or is he getting suspicious?

[After sleeping with Nick while transformed as Adalind, Juliette feared she was pregnant. It turned out she was transforming – it seems permanently – as a Hexenbiest like Adalind Schade (Claire Coffee).]

It will be recalled that in the pilot episode of “Grimm,” Aunt Marie (Kate Burton) specifically tells Nick that he has to end his relationship with Juliette. Now the Grimm 4x11 promo video is teasing, “the one [Juliette] loves most could become her mortal enemy.”

“Grimm” Season 4 airs Fridays on NBC.
