Quote #1
[Harry inflates his aunt.]
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.

STAN SHUNPIKE: Muggles? They don't see nothing, do they?
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.
Quote #3
MINISTER: She has been properly punctured and her memory modified. She will have no recollection of the incident whatsoever.
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.
