Does anybody know what happened to Lavender Brown after the Battle of Hogwarts? In the book it says she’s seen stirring feebly after Hermoine blasts Greyback off of her. In the movie she looks dead. 

To answer: it’s up for interpretation. The movie killed her, they confirmed that they killed her in the page to screen book. So in the movie verse she is absolutely dead. The book was never explained. She’s seen stirring which could mean she wound up being fine just as much as it could mean she died later.

same with her being a (or part) werewolf or not, it’s never actually said if greyback made it to her or bit her but it’s worded in a way that he could have.
