Portland is rainy. It’s moody. It’s the perfect place for a cop to find out he’s actually a monster hunter descended from the Brothers Grimm. If you’re just starting or you’re back for a rewatch, you’ve probably realized that a tv series grimm episode guide isn’t just a luxury—it’s a necessity. The show starts as a "monster of the week" procedural but quickly spirals into a massive global conspiracy involving royal families, ancient keys, and a literal magic stick.
Honestly, the first season can feel a bit slow. Stick with it.
Nick Burkhardt, played by David Giuntoli, spends the first few episodes looking perpetually confused. He’s seeing people’s faces ripple into animalistic "Wesen" forms. It’s weird. It’s gross. But the lore builds fast. Unlike other supernatural shows of the era, Grimm didn't just borrow from European folklore; it expanded it into a complex biological hierarchy. You have the Blutbad (wolves), the Bauerschwein (pigs), and the genuinely terrifying Hexenbiests (witches).
The Core Seasons: Where the TV Series Grimm Episode Guide Gets Complicated
The pilot episode sets the stage, but the show doesn't really find its legs until we meet Monroe. Silas Weir Mitchell's portrayal of a reformed, clock-fixing Blutbad is the heart of the series. If you're looking for the essential episodes in Season 1, you have to watch "Beeware" and the finale, "Woman in Black."
Season 2 is where the stakes get real.
This is when the show introduces the "Keys." There are seven of them. They supposedly lead to a treasure hidden by the original Grimms during the Crusades. Most fans get frustrated here because the show drops this plot point for years at a time. Seriously. You’ll go through half of Season 3 wondering if the writers forgot about the keys entirely. They didn't. They just took a very long scenic route through some weirder Wesen drama.

Why Season 3 and 4 Change Everything
The mid-series slump is a myth here.
In Season 3, we get the introduction of Trubel (Jacqueline Toboni). She’s a younger, rougher Grimm who doesn't have the "cop" filter Nick has. Her arrival in the episode "Nobody Knows the Trubel I've Seen" shifts the dynamic from a buddy-cop show to a full-on war story. Then comes the Season 4 finale. If you haven't seen it, brace yourself. It's brutal. It’s the episode where the showrunners basically decided to burn the status quo to the ground.
Adalind Schade, the Hexenbiest who starts as a villain, undergoes one of the most bizarre and yet somehow earned redemption arcs in TV history. It involves a "Contaminatio Morphologia" ritual that is as disgusting as it sounds. You’ve got to appreciate the practical effects team on this show. They used a mix of CGI and old-school prosthetics that still holds up better than most 2026 streaming originals.
Navigating the Black Claw and Wesenrein Arcs
By the time you hit Season 5, the tv series grimm episode guide shifts toward a singular, overarching conflict: Black Claw. This is a pro-Wesen terrorist organization that wants to stop hiding. They want to rule.
- "Wesen Nacht" (Season 5, Episode 6) is the turning point.
- The episodes become much more serialized.
- Nick's loft becomes a fortress.
It's grim. Pun intended. The show loses some of its whimsical fairytale charm during this era and replaces it with high-stakes political intrigue. Some fans hated the transition, but it was necessary. You can only solve so many "wolf eats sheep" crimes before the world has to get bigger.

The Royal Families, who were the primary antagonists for the first four seasons, get sidelined in a way that feels a bit abrupt. King Frederick's exit is... well, it involves a helicopter and a very angry Meisner. Meisner is a fan favorite for a reason. He’s the guy who does the dirty work the Grimms can’t always justify.
The Final Stretch: Seven Years of Bad Luck?
Season 6 was shortened to 13 episodes. You can feel the rush.
The showrunners, David Greenwalt and Jim Kouf, had to wrap up the mystery of the "Magic Stick" (the thing the keys actually led to) and the "Zerstörer," a god-like entity from another dimension. It’s a lot. The episode "Blood Magic" starts the final descent into the series finale.
The finale, "The End," is polarizing. It leans heavily into the "power of blood and ancestors" theme. Is it cheesy? A little. Does it provide closure? Absolutely. Seeing the next generation of Grimms in the flash-forward is the kind of fanservice that actually works because we spent six years watching Nick struggle to build a world where his kid could be safe.
Mythological Accuracy vs. Show Lore
Let’s be clear about one thing. The show plays fast and loose with the actual Grimm fairy tales. The real stories by Jacob and Wilhelm Grimm were much darker and lacked the "human-animal hybrid" biology the show created. The show is more of a "what if the stories were based on a misunderstanding of a biological subspecies?" premise.

For instance, the "Ziegevolk" (Goat-people) use pheromones to seduce people. In the original folklore, it’s usually just magic or deals with the devil. Grimm tries to give everything a pseudo-scientific explanation. It’s "Wesenology."
How to Watch Grimm Today Without Getting Lost
If you want to experience the show properly, don't skip the "Ahnenerbe" episodes. These are the ones that deal with the history of the Grimms as a task force for the Royals.
- Watch for the Latin titles. Every episode starts with a quote from a fairy tale or myth. They usually give away the ending if you know the source material.
- Pay attention to the background. The spice shop owned by Rosalee is filled with real-world herbs mixed with fictional ones like "Jaborandi Bark."
- Don't ignore the keys. Even when the show does, keep a mental map of where they are.
The show ended in 2017, but the community is still active because there hasn't been another show that quite captures this specific "Supernatural meets Law & Order" vibe. There were talks of a spinoff with a female lead, but that’s been in development hell for years. For now, the original 123 episodes are all we have.
Actionable Steps for Your Rewatch or First Run
To get the most out of your Grimm experience, stop treating it like a background show.
Start by tracking the "Wesen of the Week" against the actual Grimm's Fairy Tales; you'll find the writers left clever Easter eggs that explain why certain historical figures (like Hitler or Napoleon) were actually Wesen or Grimms in this universe. Use a dedicated tracker for the "Seven Keys" plotline, as the show's pacing makes it easy to lose track of which Royal family member currently holds which artifact. Finally, pay close attention to the evolution of the "Grimm Diaries." The sketches in those books were hand-drawn by artists on set and contain lore that is often mentioned in passing but never fully explained on screen. If you find yourself confused by the sudden shift in the final season’s tone, go back and watch the Season 5 premiere again—the seeds for the "Other Place" were planted much earlier than most viewers realize.
The best way to consume this series is in chunks. The first ten episodes are a prologue. The middle seasons are a war. The final season is a sprint. Happy hunting. ---
