Although there has been no confirmation about the next season and its air date, yet fans are speculating that the next season of "Grimm" might return in October 2016, according to Parent Herald.

Moreover, Trubel was upset about in sufficient and inefficient manpower in the fight against Black Claw, but finally managed to make things work.
