1x18 — Grimm

"Plumed Serpent" is the eighteenth episode of Grimm’s first season, and it serves as a classic example of the show’s sweet spot: blending police procedural drama with dark fairy-tale lore, while throwing a major wrench into the personal lives of its characters.

Not all Wesen are killers by nature, but some are predators by design. The Lausenschlange doesn’t need claws or fangs—she uses human desire as her weapon. The Real Drama: Juliette Under a Love Spell While Nick is chasing the serpent, his live-in girlfriend Juliette (Bitsie Tulloch) is dealing with her own bizarre situation. Her friend, a bartender named Rolfe , has been acting strange. It turns out Rolfe is also a Lausenschlange (Sasha’s ex-boyfriend), and he’s desperate to win her back. Grimm 1x18

While the episode features a monster-of-the-week (a Lausenschlange , or “lurking snake”), the real focus is on the emotional fallout of a love spell—and the introduction of a new, persistent threat. The episode opens with a man being stabbed in a parking garage by a beautiful, mysterious woman. The twist? When Nick Burkhardt (David Giuntoli) arrives on the scene, the victim refuses to identify his attacker. Why? Because he’s completely and obsessively in love with her.
