First up, Grimm has added Michael Grant Terry (Bones) in a multi-episode guest arc. He will play Ryan, a student interning at Portland Police Department who begins to idolize Nick.
Next, Hannibal has added actress Lara Jean Chorostecki (Camelot, Copper). She plays Freddie Lounds, a sleazy tabloid reporter. In previous incarnations of the Hannibal Lecter story, Lounds was a man. The feminized role will be a more "sophisticated manipulator" than her male predecessors.
