You know that feeling when you finally think the bad guy is gone, only to realize they’ve been sitting at your dinner table for months? That is basically the vibe of Locke and Key season 2. It’s messy. It’s dark. Honestly, it’s way more stressful than the first season because we, the audience, are in on a secret that the Locke kids are totally oblivious to for way too long.
While Tyler, Kinsey, and Bode are busy trying to have a "normal" life in Matheson, we’re stuck watching Gabe—who is actually the demon Dodge—play house. It’s awkward and terrifying. Most people went into the second season expecting more whimsical key-hunting, but what we actually got was a brutal lesson in how magic destroys as much as it heals.
What Most People Get Wrong About the Gabe Twist
There is a common misconception that Gabe was just a new character introduced to be a love interest. Nope. If you rewatch the end of season one, you see the seeds planted, but season two is where Griffin Gluck really gets to lean into the villainy. He isn't just a demon; he’s a demon trying to understand human connection while simultaneously planning to enslave the town.
It’s a weird dynamic.
Gabe/Dodge spends a lot of time trying to "belong," which makes the betrayal feel way more personal for Kinsey. When she finally uses the Head Key on Eden and sees the truth, it’s one of the most satisfying "oh crap" moments in the series. But by then, the damage is already starting.

The New Keys That Actually Changed the Game
In the first season, the keys felt like toys. In Locke and Key season 2, they feel like weapons. We got a bunch of new ones, but a few really stand out because of how they shift the stakes:
- The Hercules Key: This one is pure muscle. It gives the user insane strength through a special belt. It’s flashy, sure, but it’s mostly there for the physical confrontations that get way more intense this year.
- The Small World Key: This is probably the coolest visual in the show. It links a dollhouse version of Keyhouse to the real building. If you drop a giant gummy bear in the dollhouse kitchen, a building-sized candy appears in the real one. It’s whimsical until a demon tries to use it to crush everyone.
- The Memory Key: This is the emotional heart of the season. Adults in this universe naturally forget magic when they turn 18. It’s a biological "cleansing" that Tyler is terrified of. The Memory Key allows an adult to keep those memories, but as we see with Uncle Duncan, forcing those memories back isn't exactly a painless process.
Why the Alpha Key is the Real Tragedy
Let’s talk about Jackie. Honestly, her arc is what makes the second season so much heavier than the first. Tyler is desperate. He’s watching the girl he loves lose her connection to magic, and then she gets turned into a demon.
Tyler thinks he can be the hero. He works with Duncan to forge the Alpha Key, believing it will "cure" the demonic possession. And it does—but the cost is horrifying. It turns out that when you rip a demon out of a human soul using the Alpha Key, the human body can't handle the vacuum.
Jackie dies in his arms.

It’s a massive turning point. It’s why Tyler eventually decides he doesn't want to remember magic. He chooses the "forgetting" because the grief is too much to carry. This is a huge departure from the "kids on an adventure" trope. It’s a very real look at trauma and the choices we make to survive it.
The Origin Story Nobody Expected
One of the best things about this season is the jump back to the 1700s. We finally get to see where the keys came from. It wasn't just some wizard in a basement. It was a Revolutionary War captain named Frederick Gideon who stumbled upon a portal in a sea cave.
Kevin Durand plays Gideon with this terrifying, old-world menace. We see the "Whispering Iron"—which is actually the cooled remains of demons trying to push into our world—being forged into the very first keys. It grounds the mythology in a way that feels historical and gritty.
The Ending Explained (Simply)
The finale is a chaotic mess of falling houses and angel wings. Kinsey uses the Angel Key to fly, which looks incredible on screen, and the Lockes finally manage to take down Dodge. But they don't do it alone.

Uncle Duncan turns out to be the secret weapon. Because he was forced to forge the Demon Key, the demons created by it have to obey him. It’s a poetic bit of justice. He turns Gabe’s own army against him.
But even though Dodge is gone—and Lucas is finally free of her—the "happily ever after" is short-lived. Eden, being the chaotic mess that she is, summons the echo of Captain Gideon. He immediately kills her (RIP Eden, you were a fun villain) and heads out into the world with the Anywhere Key.
Actionable Insights for Your Next Rewatch
If you’re planning on diving back into the series or just finished and feel a bit lost, keep these things in mind:
- Watch the Background Characters: The showrunners love to hide hints about who is possessed and who isn't. Gabe’s behavior in the early episodes is totally different once you know he’s Dodge.
- Compare to the Comics: If you haven't read the Joe Hill graphic novels, do it. The show is much "lighter" than the books, which are straight-up horror. Seeing how they adapted things like the Head Key is fascinating.
- Track the Trauma: Notice how each Locke sibling handles the keys. Bode sees them as wonder, Kinsey sees them as a way to fix her flaws, and Tyler sees them as a burden. This stays consistent all the way through the finale.
The world of Keyhouse is never really safe. Even when a door is locked, there is always another key waiting to be found.
Next Step for You: Go back to Season 2, Episode 8 ("Irons in the Fire") and pay close attention to the forging scene. It explains the "intent" behind the keys, which is the most important rule in the series. Understanding that the creator's soul goes into the metal makes the ending of the season hit much harder.
