Harry Potter Fans Have A Dark Theory About The Trolley Cart Lady

Note: This article contains spoilers for Harry Potter and the Cursed Child

A Harry Potter fan has taken to Reddit with a chilling theory about the trolley cart lady, who sells snacks to the students aboard the Hogwarts Express.

"This f*cking lady has put herself in a business position with absolutely no competition," they wrote. "Her clientele is a bunch of children with no adult supervision, and a lack of self control skills to be fully developed yet."

However it wasn't just her business model that's got the fan riled up. They did landed upon something even more disturbing..

"[She] is probably the reason the Dementors knew about the Hogwarts Express, and let them on to boot knowing that she would make bank on her marked up enchanted Hershey bars. Must be nice only having to work four days a year."

Other fans were quick to chime in with their opinions on this theory.

But does it add up? Well... kind of, yeah!

In Cursed Child the trolley lady is revealed to be some sort of security for the train - one whose hands can transform into sharp spikes.

This discovery is made when Albus Potter and Scorpius Malfoy attempt to leave the train early. Winding up on the roof somehow, the trolley lady appears up there with them.

She reveals that she has been the trolley witch for nearly 200 years, and then her hands transform into spikes as she tells the troublemakers to return to their seats.

And if that's not weird enough, she throws a pumpkin pasty at the duo which turns out to be a GRENADE!

As one fan put it: "As we all know, the trolley cart lady is in fact a Lovecraftian horror with spikes for hands. This sounds like absurdist humour, but its JK approved somehow."
