Locke & Key is coming to Netflix next month, and our bodies are ready. The 10-episode adaptation of the incredible graphic novels by the same name showed off its first official trailer on Wednesday.

Judging by reactions around the web, the streaming service is going to have a hit on its hands. Some are even calling it Netflix’s “next horror hit.”

If the excitement of the first trailer isn’t enough to get you revved up, how about the fact there was a secret buried at the end? It turns out a way to see the very first scene in the series is “unlocked” if you watch the video to the very end.

For those who haven’t watched the trailer yet, (what are you waiting for?) or haven’t read the graphic novels yet, turn away now because spoilers are on the way.

Rendell Locke is Dead

After the action in the first Locke & Key trailer ends and just before the video cuts off, the words Rendelllockisdead.com smoke across the bottom of the screen. A visit to that website redirects you to another YouTube video, this one, the opening scene of the first episode.

For devotees of the graphic novels, it’s a head-scratcher. It opens with a man getting a phone call from a mysterious woman who informs him that Rendell Locke is dead. Those who have read the comics know Rendell is the father of the series’ main protagonists, Tyler, Kinsey, and Bode.

After the news of Rendell’s death, the unnamed man asks how he died, and the woman responds, “you know how.” This appears to be a pretty major departure from the books.

In the Locke & Key graphic novels, Rendell (a guidance counselor at Tyler’s high school) is murdered by one of his students. In the opening scene, while it’s not divulged how he dies, the ominous way in which the woman tells the man he knows how the elder Locke dies implies this has changed.

Shortly after getting the news of Rendell Locke’s death, our unnamed hero takes out a key, jobs it into his torso, and turns it. The result is that he and then his house is set ablaze.

None of this happens in the books, which means we also have no idea why the news of Rendell’s death leads him to take this final action. A shift in the storytelling from the get-go could might not bode well for those who were hoping the Locke & Key Netflix series would religiously follow the graphic novels.

All ten episodes for the show drop on February 7, 2020.
