If you know anything about Stephen King adaptations, you know to expect the unexpected. Prime Video’s 2026 Carrie television series is no different. This time, Carrie White’s nightmare gets a modern upgrade, and by that, I mean social media cyberbullying and mom-turned-influencers. But while everyone’s busy watching Carrie’s life spiral, there’s another big question hanging in the air: Who’s the narrator of this whole thing?
Mike Flanagan, the creator behind The Haunting of Hill House and Midnight Mass, is at the helm, and the show follows Carrie White (played by Summer H. Howell) as she tries to survive her new high school. She’s got a controlling mom, Margaret White (played by Samantha Sloyan), classmates who are basically the definition of mean, and yup, telekinetic powers. Throughout the series, there’s a mysterious female voice telling stories about women with supernatural powers — and it’s not revealed until pretty late in the series.
So, that mysterious voice narrating Carrie? Turns out, it’s Kate Siegel — aka Mike Flanagan’s go-to scream queen and wife. If you’ve binged The Haunting of Hill House, The Fall of the House of Usher, or Midnight Mass, you probably clocked her voice before the show even dropped the big reveal.Â
In Carrie, Siegel steps in as Adelaide, a character who seems like a background character at first but ends up being way more important to Carrie’s story than anyone could have guessed. All season long, Adelaide is busy interviewing anyone and everyone tied to Carrie and the chaos in Chamberlain. At first, it seems like she is just a director making a documentary film, but as the episodes roll on, it gets obvious: Adelaide is hiding something. And here’s the twist — she’s not just telling Carrie’s story from the sidelines. She’s actually tangled up in the supernatural world that Carrie is only just starting to figure out.
The character Adelaide is actually nowhere to be found in Stephen King’s original 1974 novel. She’s brand new for Flanagan’s version, and honestly, she flips the whole story on its head. Throughout the series, Adelaide drops hints about other women with supernatural powers, making it clear that Carrie might not be as one-of-a-kind as she thinks. Those stories that seem like random background details at first? They end up being a pretty big deal by the time the season wraps.
By the time the finale hits, the truth is out: Adelaide has powers of her own. In one of the wildest moments of the show, she straight-up uses her abilities to stop Margaret White’s heart, taking out Carrie’s mom. That jaw-dropping scene proves Adelaide isn’t just poking around in other people’s business — she’s part of the club. And with her ties to a whole network of supernaturally gifted women, it’s clear there’s way more to Carrie’s powers.
But Adelaide’s big reveal doesn’t just flip the script on season one — it sets up the tone for season two. Flanagan mentioned that his dream scenario is to make three seasons, as he sees Carrie as a trilogy. Unlike the book or any of the old movies, this Carrie actually survives prom night. She gets out with Emaline, another girl with powers, which means the story is wide open for a whole new chapter.
Now that Adelaide is linked to a whole crew of women with psychic powers, Carrie might finally find people who get what she’s dealing with. But is Adelaide actually looking out for her, or is there something darker going on? Knowing Flanagan, it’s a safe bet Adelaide still has plenty of secrets she’s not sharing. So, if viewers do get another season, expect Adelaide to play an even bigger role as Carrie figures out her powers and dives deeper into the supernatural side of things.
And until a Season 2 is confirmed, one thing is certain: Adelaide was never just a mysterious voice narrating Carrie’s life. She was connected to the story all along, and her shocking reveal proves that there’s still plenty left to uncover about the world of Carrie.
