Honestly, if you were a fan of the Wesen-hunting adventures in Portland back in the day, the mention of grimm tv show season 6 probably triggers a weird mix of nostalgia and mild frustration. It was a rollercoaster. One minute we’re dealing with the usual "monster of the week," and the next, the entire cast is being systematically wiped out by an interdimensional skeleton with a magic stick.
It’s been years since the finale aired, yet the way it wrapped up is still a massive talking point in sci-fi circles. Most shows go out with a whimper or a polite bow, but Grimm decided to go full "nuclear option."
The 13-Episode Crunch: What Really Happened Behind the Scenes
Most viewers noticed something was off right from the start of the season. The pacing felt... frantic. Normally, we got a lush 22-episode run to let the mysteries breathe. But for the final outing, NBC slashed the order to just 13 episodes.
There’s been a lot of chatter about why this happened. At the time, NBC had a crowded slate with shows like Chicago Justice and The Blacklist spin-offs taking up space. By shortening the season, they could move Grimm to a mid-season slot to fill gaps. While the network claimed it gave them "flexibility," fans knew the writing was on the wall.
The writers, David Greenwalt and Jim Kouf, had to cram what was likely two seasons' worth of mythology into half the time. This is why the Black Claw storyline—the massive global Wesen uprising that dominated season 5—was basically hand-waved away in the first few episodes. It’s a bummer, really. We spent years building up this shadow war, only for it to end with a few phone calls and some off-screen cleanup so the show could focus on the "Magic Stick" mystery.
Why Season 6 Felt Different (And Why It Worked)
Despite the rush, there’s something special about the vibe of this season. It felt like a "greatest hits" tour. Because they knew the end was coming, the stakes actually mattered. You've got Nick Burkhardt, played by David Giuntoli, going from a badge-wearing detective to a full-blown fugitive within the first twenty minutes.

The dynamic between Nick and Captain Renard finally boiled over. After years of "are they allies or enemies," Renard went full villain—until he didn't. That weird tension culminated in "Oh Captain, My Captain," where Nick uses a potion to turn into Renard. Seeing Giuntoli mimic Sasha Roiz’s mannerisms was peak Grimm comedy. It was silly, high-stakes, and a bit gross. Everything we loved about the show.
Then you have the "Eve" situation. Bitsie Tulloch had to pivot from the vengeful Hexenbiest machine back into someone with human emotions. Watching her character try to reconcile Juliette’s memories with Eve’s cold logic added a layer of tragedy that often gets overlooked.
The Zerstörer: The Villain No One Saw Coming
The final big bad, the Zerstörer, is a polarizing figure. He shows up late in the game, coming through a mirror from a "primitive" dimension that looks like a dark version of the Black Forest.
- The Power Level: This guy wasn't just another Wesen. He was a god-tier threat.
- The Motive: He wanted Diana, Nick and Adalind's daughter, to be his "child bride" or queen (it was never quite clear and honestly pretty creepy).
- The Staff: He carried a staff that was missing one piece—the shard Nick had been carrying around since they found it in Germany.
A lot of fans felt he was a bit "out of nowhere." It’s a fair critique. When you introduce a world-ending threat in episode 11 of a 13-episode season, it can feel like the writers are just throwing the kitchen sink at the wall.
The Finale: "The End" and the Trauma of the Spice Shop
If you want to talk about grimm tv show season 6, you have to talk about the massacre. The series finale, titled "The End," is brutal.

In a span of about 30 minutes, we watch Hank and Wu get gunned down at the precinct. Then, the Zerstörer hits the spice shop. Eve dies. Then Adalind. Then Renard. Finally, Monroe and Rosalee—while she’s pregnant with triplets!—are taken out. It was heart-wrenching. Seeing Nick lose everyone he loved was a heavy lift for the actors, and Giuntoli really sold the desperation.
Of course, it was all a bit of a fake-out. By using the "strength of his blood" and getting a literal pep talk from the ghosts of his mother and Aunt Marie, Nick manages to kill the Zerstörer. The moment the staff is made whole, a portal opens, and Nick is pulled back in time to the moment he first stepped through the mirror.
Everyone is alive. Nobody remembers the massacre except Nick.
Some people call this a "deus ex machina" or a "it was all a dream" cop-out. Personally? I think the show earned it. After six years of misery, seeing the gang alive and Rosalee still pregnant felt like the right kind of closure, even if it was a bit tidy.
The Legacy: Is There More Grimm in 2026?
Fast forward to today, and the hunger for more Grimm hasn't died down. There have been rumors of a female-led spin-off for years that never quite made it out of development.

However, the latest buzz is much more concrete. As of 2025 and heading into 2026, there are confirmed reports that Peacock is developing a Grimm reboot project. Elizabeth Tulloch even mentioned in recent interviews that a script exists and David Giuntoli has met with the team.
The flash-forward at the very end of season 6—showing a grown-up Kelly and Diana hunting Wesen with Monroe’s triplets—set the perfect stage for a sequel. Whether we get a continuation of that story or a total reset remains to be seen, but the mythology is clearly too rich to stay buried.
What to Do Next if You’re Re-watching
If you’re diving back into the series or finishing it for the first time, keep an eye on the background details of the Wesen Council and the Royal Families. Those threads were left dangling, and they’re likely where a reboot will pick up.
Actionable Steps:
- Check the Comics: If the ending of season 6 left you wanting more, Dynamite Entertainment published a Grimm comic series that explores the "Keys" mythology in much more detail than the show had time for.
- Listen to The Grimmcast: Stars Bitsie Tulloch, Claire Coffee, and Bree Turner started a rewatch podcast. It’s the best way to get the "real" stories of what was happening on set during those final 13 episodes.
- Watch the "Blind Love" Episode: If the finale was too dark for you, go back and watch Episode 7 of Season 6. It’s a hilarious bottle episode where everyone falls in love with the wrong person at a hotel. It's the perfect palate cleanser for the series finale.
