Complete story — includes the ending

The station is abuzz as Nick and Hank are called to a case where an innocent flash mob results in a gruesome homicide. The homicide is ruled the result of anaphylactic shock, where someone was able to collect a significant amount of bee venom to inject as a weapon. Soon, another flash mob results in another homicide, also connected to the first person as they worked together. Nick and Monroe determine that Mellifers are behind it, and are seeking revenge against the Hexenbiests that closed their papermill. He is surprised to learn that the last intended victim is the Hexenbiest who attacked him in the hospital (Adalind). He and Hank go to protect her as bees swarm the apartment they're in. The Hexenbiest and the Mellifer queen behind the attacks fight in the basement, and the Mellifer tells Nick they were being silenced to try to protect him. He tells the queen to stand down, but she doesn't, so he shoots her. At the close of the episode, he thinks about how his role as a police officer and his role as a Grimm can be at odds sometimes. Opening quote: " She'll sting you one day. Oh, ever so gently, so you hardly even feel it. 'Til you fall dead. "
