Harry Potter and the Prisoner of Azkaban The Supernatural

We're not sure what spell Harry uses to inflate his aunt. He does it without saying anything or using a wand. Although it's satisfying (because Marge is so freaking awful) it makes Harry seem almost like Carrie, unable to control his abilities. Don't take Harry Potter to the prom…yet.

Do they? We're not sure. We seem to still be figuring out this world's rules of magic three books in. One continuity error here is that a flying car was seen by Muggles in the previous book.

Because wizards aren't supposed to do magic outside of Hogwarts, Harry could be in a pile of deep doo-doo-flavored Bertie Botts jellybeans for inflating Aunt Marge. It's handy that wizards and witches have a Men in Black-like ability to erase memories. Erasing her memory means Harry gets off without punishment…this time.

Hermione has always been a good student, but she's suspiciously good this term. She's in almost every class, showing up seemingly out of nowhere in her seat. Hermione's behavior is weird even by Hogwarts standards, and it makes Ron and Harry (and us!) wonder what she's up to. And if she keeps sneaking up on people like this she'll need to wear a bell.

First of all, what magic is Ron using to actually be observant for once? And second, by the time Hermione says this, we're absolutely positive that she's in two classes at once, but we just don't know how she's doing it yet. We will eventually be introduced to a new magical artifact, the Time Turner.

Because werewolves don't actually exist (at least that's what they want you to think!) a work of fantasy needs to build its own lore about the creatures. Harry Potter's werewolf lore is fairly traditional, down to the full moon and the uncontrollable behavior.

Tension is increased at the end when Dumbledore tells us that time magic isn't something that happens on a regular basis. Blowing people up to four times their original size: yes. Time travel: not so much.
