JK Rowling’s said in interviews that if Voldemort ran into a boggart — a creature that takes the form of whatever is most feared by its observer — he would see it as his own corpse.
Man that guy was suuuuper into not dying.
According to the Independent, that’s because Rowling could so easily imagine Dumbledore humming to himself.
But also? Finding out what Dumbledore meant got a lot of fans theorizing that Dumbledore was an animagus, buzzing around and overhearing every conversation at Hogwarts. How else did he know everything that was going on? (We still don’t know.)
We’ve heard from JK Rowling that she decided to get Ron and Hermione together early in the series, and could start to feel that they weren’t right for each other, but she stuck to the plan. Personally, I think Hermione should’ve ended up with Harry (even though even the Chosen One who defeated the most powerful Dark Wizard of all time still doesn’t really deserve her).
