"To Protect and Serve Man" is the 11th episode of the supernatural drama television series Grimm of season 2 and the 33rd overall, which premiered on November 9, 2012, on the cable network NBC.
Renard (Sasha Roiz) arrives at the spice shop hoping to collect the potion to reverse his obsession, bringing Juliette (Bitsie Tulloch) with him.
Club's Les Chappell gave the episode a "B+" grade and wrote, "'To Protect And Serve Man' doesn't do much to break this trend — with the exception of one promising development I'll get to later — but as a case of the week it's above duller installments like 'The Bottle Imp' and 'The Other Side.'
This is largely because it's tied so closely to the smartest move Grimm made all season, the decision to bring Hank into the fold and let him in on Nick's secret life.
Hank's new perspective leads him to reconsider a case from seven years earlier, where an Army veteran named Craig Ferrin shot two brothers and claimed they were 'monsters' who wanted to eat him.
"[4] Nick McHatton from TV Fanatic, gave a 4.2 star rating out of 5, stating: "As much as I tend to complain when Grimm decides to veer back to its procedural roots, tonight's episode didn't bother me in the slightest.
