Grimm season 3

what happens

Under the effects of the Cracher-Mortel toxin, Nick causes the plane carrying him to Europe to crash, killing Baron Samedi. A residual effect of the Cracher-Mortel toxin, however, causes Nick's endurance to be increased along with his strength. Juliette, with her new-found knowledge of the Wesen world, enthusiastically joins Nick, Hank, Monroe, and Rosalee in their adventures. Adalind's pregnancy continues as she goes through the Contaminatio Ritualis with the help of Stefania, and Captain Renard realizes that the rumored royal baby being offered for sale could be Adalind's. Captain Renard arranges for the assassination of his half brother, Eric, who is replaced in the royal hierarchy by his cousin, Viktor. Monroe proposes to Rosalee, and she happily accepts.
