After five season, NBC is giving Grimm a short sixth season to wrap everything up and say farewell. A notably breakout in 2011, Grimm stayed strong enough for five full seasons of wesen filled action. Now, there is a ton of story to complete in only 13 episodes.
With the nefarious forces of Black Claw silenced by Nick, he will finally faces Capt. Sean Renard. Meanwhile, Monroe and Rosalee grapple with having a child and Eve faces identity issues that may be her undoing. Personally, I think the team can wrap up the remaining stories and allow decent closure.
