Ep 14. Natural Born Wesen

Nick and Hank are called to the scene of a double homicide, and soon discover that the victims were shot in mid-transformation from human to Wesen. As they investigate the case, they learn that the shooter may be a "Natural Born Wesen," or a person who is born with the ability to change into a Wesen without the aid of a Grimm's powers.

Meanwhile, Juliette struggles to come to terms with Nick's secret life as a Grimm, and seeks advice from Monroe. Monroe, who is still recovering from his near-death experience at the hands of Angelina, encourages Juliette to learn more about Grimm history in order to better understand Nick's world.

At the same time, Captain Renard continues to deal with the aftermath of his encounter with Adalind. He seeks the help of a Hexenbiest, who gives him a potion to weaken Adalind's powers. However, Renard soon discovers that the potion has unexpected side effects, and he must deal with the consequences of his actions.

As the investigation into the double homicide continues, Nick and Hank discover that the shooter may be a member of a secret Wesen society known as the "Natural Born Wesen Alliance." The Alliance, which is composed of individuals who believe that Wesen are superior to humans, is determined to establish a Wesen homeland where they can live free from human persecution.

With the help of Monroe and Rosalee, Nick and Hank track down the Alliance's leader, a powerful Wesen named Jurgen. However, Jurgen is not who he seems, and Nick and Hank soon find themselves in a life-or-death struggle as they try to stop the Alliance's plan to attack a human settlement.

In the end, Nick and Hank are able to put an end to the Alliance's plans, and Nick comes face-to-face with Jurgen one last time. Meanwhile, Juliette continues her studies of Grimm history, and Captain Renard deals with the unintended consequences of his actions.

Overall, "Natural Born Wesen" is a thrilling episode that explores the darker side of Wesen society and the struggle between humans and Wesen. With plenty of action, suspense, and intrigue, it is a must-watch for fans of Grimm.
