GRIMM Exclusive: Uncomfortable Truths are Exposed in “The Son Also Rises”

How far would you go for your child?

That's a recurring theme in this week's episode of Grimm as Nick investigates a bereaved scientist whose colleagues are dropping like flies, while Monroe finds fatherhood thrust upon him all too suddenly, and Renard faces an uncomfortable truth about his daughter Diana.

In "The Son Also Rises" Nick (David Giuntoli) Hank (Russell Hornsby) and Wu (Reggie Lee) find themselves stumped by a series of impossible clues during an investigation unlike any they have had before.

Meanwhile, as the research continues into the origins of the cloth, Monroe (Silas Weir Mitchell) and Rosalee (Bree Turner) learn that Eve (Bitsie Tulloch) is still feeling the after effects of the death grip.

And Renard (Sasha Roiz) secretly reaches out to an old friend to get answers to the origins of the symbols drawn by Diana.
