The events of "Wesen Nacht" left fans with their jaws on the floor, but for Nick (David Giuntoli), Julliette's (Bitsie Tulloch) return will be earth shattering. Get ready for an awkward reunion when the cop and Eve come face to face in "Eve of Destruction."

"Nick and the gang are still reeling from the scope of the ambush and the surprise return of "Juliette," but not everything is as it seems," NBC said of the midseason premiere. "In light of the heightened Wesen violence, Monroe (Silas Weir Mitchell) and Rosalee (Bree Turner) seek answers from the Wesen Council."

At least the Grimm won't be facing down the Wesen uprising on his own. Another monster hunter is back in town, and while her motives may be dubious, Trubel (Jacqueline Toboni) will around to lend a helping hand.

"Trubel has some information for Nick that will help him get what he is looking for," NBC announced.
