Grimm S04E22 "Cry Havoc"

A few episodes back I was thinking Nick would have to kill Juliette. Then his mom was murdered (on mother's day weekend) and she crossed a line that meant she had to be taken out. Glad Trubel did it instead, he was really broken.

Long live the new queen?

Who was that FBI lady working for again?

Why didn't Kenneth woge?
