We've all wondered at some point how we will leave this earth but would you have ever thought "death by flash mob" could be one of those ways?  I'm sure Serena Dunbrook didn't think so.   

Serena, a lawyer, is found mysteriously dead following a flash mob on the street car she was riding on her way to work.  Nick and Hank arrive on the scene to find her face in a terribly grotesque state, it seems from anaphylactic shock.  But something tells me that there is a more supernatural explanation to this than just an extreme allergic reaction... 

A puncture wound by her ear suggests that something was injected in her.  The coroner reports that a large amount of bee venom was found in her system, way too much to have come from a standard bee sting though. 

Back at the station, as Nick interrogates the flash mob participants, he learns that the flash mob was organized via social media.  Both his detective and Grimm intuition causes him to zero in on one particularly suspicious character, Doug.  Sure enough, soon Doug loses his cool and his inner Wesen – a bee-like creature – reveals himself to Nick.  

At this stage it looks like the prime suspect is either a giant killer bee or a crazed bee keeper with a vendetta.  When Nick and Hank are attacked by a sudden swarm of bees while investigating a lead at a paper mill, this leads Nick to search for answers of the Grimm kind.

He soon finds out that these bee creatures, or Mellifers, just like their regular counterparts, live and operate as a community.  In the supernatural world, they are part of a "creature community switchboard" hence their natural affinity towards using social media in the mortal world. 

The Mellifers are at war with the Hexenbiests, witch-like beasts, and must destroy them in order to maintain the balance in the supernatural world.  Hexenbiests are identified by a mark on their tongue which, on further investigation with the coroner, Nick discovers Serena had.

Nick contacts Monroe for his keen Blutbad nose and this leads them to uncovering the leader of the Mellifer community, or the Queen Bee, if you will – Melissa Wincroft.  I really like the rapport that has quickly developed between Nick and Monroe.  While only appearing briefly in this week's episode, Monroe injects his usual brand of sarcasm and dry humour into the conversation.  

Adalind Schade, Serena's colleague, is identified as the next victim however when her and Nick meet he realizes they have met before.  It turns out Adalind is the Wesen from the pilot episode who had attempted to murder Aunt Marie.  In a cruel twist of irony, Nick now has to protect the person that is his enemy in the supernatural world.  

When Melissa finally catches up to Adalind, Nick's two identities collide when he realizes he has to make a decision on who to save.  Does he protect his detective job and shoot Melissa (who claims to be on the Grimms' side) or does he do his Grimm duty and shoot Adalind?  He struggles but in the end the detective in him prevails and he chooses to save the Hexenbiest (which surprised me!). 

In the closing scene we see Nick is ridden with guilt as he realizes that being both a cop and a Grimm is not easy.  His choice may come at a cost – if Melissa was telling the truth, who is coming for him?
