Monroe has to deal with a threat against his life with the help of Nick, new ally Hank, and someone from his past on an all new episode of Grimm.
There's a plague hitting the Wesen hard, Monroe and Rosalee address their feelings for one another, and another reaper comes to town on Grimm.
The bunheads finally end their interpersonal drama (or do they?), Fanny plans to move to Montana (or does she?), and everything caves in on Michelle.
