Kate Siegel’s Adelaide isn’t just a narrator. She’s a reckoning. In the final moments of Prime Video’s Carrie, the woman who’s been quietly chronicling the trauma of telekinetic girls — those with the TK gene, turns on the camera, then turns on Margaret. The kill is clean. The motive? Unspoken. And the question hanging over the entire season: Who is she really? Not Professor X. Not a savior. Just someone who’s seen too much, and maybe done too much. Her name is Adelaide. Her role was never meant to be explained in eight episodes. It was meant to haunt. 

Siegel, who co-wrote and directed one episode. “Social Studies”, and has spent years building her legacy with Mike Flanagan, says she had free rein. “I could make her whoever I wanted,” she told Deadline. That freedom shows. Adelaide doesn’t wear a cape. She wears a neutral tone. A calm that feels less like control and more like calculation. She interviews survivors of the prom fire like a documentary filmmaker, but her gaze lingers longer than any journalist should. She knows things. She’s been watching. From where? And why? 

The show’s framing device. The idea that Carrie’s story is part of a larger archive of psychic women, was always there in Stephen King’s original. But it’s only now, with Siegel at the helm, that it becomes a weapon. She’s not just retelling history. She’s editing it. The other girls in the room? They’re not just witnesses. They’re subjects. Or candidates. Who sent them to Chamberlain High? Why did they all have the Shine? And what happens when the next girl lights up? 

Flanagan fans know this rhythm. The quiet woman with a past. The one who’s not quite on your side. Siegel’s work with him. Oculus, Gerald’s Game, The Haunting of Hill House, has always leaned into female rage as narrative fuel. Here, it’s not just rage. It’s inheritance. “She represents this framing device that’s never been fully realized,” Siegel said. “Stephen King points to the fact that this is a bigger story.” And now, so does she. 

No word yet on Season 2. Flanagan hasn’t confirmed anything. Siegel says she knows nothing. But the questions are already circling. Who’s filming Adelaide? Is she the guardian. Or the gatekeeper? And if she’s not the villain, what’s the real threat? 

Next up for Siegel: directing her feature debut, Method, a horror-thriller she calls “close to my heart.” No release date. No cast. But after Carrie, the world might finally be ready to listen. 

And if you thought the prom night fire was the end… well, Adelaide’s still got footage to deliver.
