The Harry Potter author and Fantastic Beasts screenwriter divulges a couple of tantalizing details about the film, including why everyone is heading to Paris. Spoiler alert: It’s all about Credence. Speaking of the Obscurus, Rowling also explains what’s going on in the character’s head. We also see Grindelwald has an interest in him.

A few other tidbits to share: A few months have passed since the end of the last film, and Rowling says “we’re now getting to the meat of the story. Everything gets darker and more intricate. Whatever you might think at the end of the movie might not be the case.” Watch below:
