In Grimm Season 4 Episode 5, a woman is tormented by a talking wolf-headed man - she knows it's impossible, and people keep telling her that she's imagining it, but the wolf-man won't leave her alone, to the point that she's suffering a mental breakdown. When Nick and Hank investigate, they sense that there is Wesen involvement, but they can't prove anything, and Nick doesn't want to bring in Trubel. Nick and Juliette also learn that to break Adalind's de-Grimming curse, they must sleep together... but the catch is that Juliette needs to use the same potion to disguise herself as Adalind. Meanwhile, Adalind herself is tortured by various mazes and traps as she desperately tries to find her way through the castle. And Bud comes to Trubel with a Grimm matter: Nick's de-Grimming has reached the ears of a rather hostile Klaustreich who has a bone to pick with Nick. Renard tells his mother Elizabeth that Nick's mother Kelly has the baby, and Elizabeth vows to track her down. Learn how all these threads link together and discover the truth of the wolf-man when you watch Grimm Season 4 Episode 5 online!
