It’s been over a year since Fantastic Beasts and Where to Find Them apparated into screens, and it was high time we got news about that sequel. Finally, Warner released the first trailer for Fantastic Beasts: The Crimes of Grindelwald, and Harry Potter fans all over are gaping into the blatant plot hole.

Seconds into the teaser, we see a group of wizards and witches apparating into the bridge leading to the Hogwarts castle. While that might seem like an everyday occurrence for the casual Harry Potter movie viewer, J.K. Rowling made a constant point in the books that there was no apparating in Hogwarts grounds. Constant point. In fact, Hermione Granger spent years reminding everyone that this wasn’t possible.

While house elves use a different type of magic and can apparate on school grounds, wizards are not allowed. The only exception is during Ministry-sanctioned apparating classes.

So, why is it that Crimes of Grindelwald, with its screenplay written by J.K. Rowling herself, has people casually apparating into the school?

While it sounds like fangirl nitpicking, I promise I’m not the only one concerned with this.

We might be facing a severely annoying plot hole, but there’s still a chance Rowling is messing with fans’ heads. So far, the social media-savvy author hasn’t addressed the subject on her Twitter account. This could either mean she’s realized her horrible mistake, or that answering what’s up with the apparating could somehow be a spoiler for the movie.

Let’s keep in mind that all our knowledge of Hogwarts is from the 1990’s, where Harry Potter was set, whereas Fantastic Beasts occurs in 1927. At that time, Albus Dumbledore wasn’t even the school’s headmaster, but rather its Transfiguration teacher. While there hasn’t been a broad explanation on when the anti-apparating spells were placed on Hogwarts grounds, there’s a good chance it was Dumbledore himself who put them in place.

In fact, it’s possible the spell was put up as a consequence of something that transpired during Grindelwald’s reign of terror. Could there have been a previous Battle of Hogwarts we’re not aware of?

Fantastic Beasts: The Crimes of Grindelwald is a follow-up of 2016’s Fantastic Beasts and Where to Find Them. Set in the 1920’s, much of the sequel will follow the attempts of Newt Scamander (Eddie Redmayne), Albus Dumbledore (Jude Law) and the entire magical world in stopping purity-obsessed dark wizard Gellert Grindelwald (Johnny Depp).

The film will hit theaters on November 16.
