New Fantastic Beasts trailer confirms Harry Potter theory that people have been obsessing over

The movie is going to pick up where 2016's Fantastic Beasts And Where To Find Them left off.

In the new trailer, we finally see a bit of the magical creature's origin story — including the fact that she was once a witch.

As soon as the detail was revealed, people were quick to speculate that Nagini must be an Animagus, like Peter Pettigrew (aka Wormtail) — prompting J.K. Rowling herself to quickly set the record straight.
