I bet that even JK Rowling wouldn’t be able to keep up with this lomdisheh discussion. With so many Harry Potter experts here, somebody should write a Peirush Al Harry Potter. The sefer would be a best seller! LOL
This is just the tip of the iceberg. There are many more questions, perhaps we will discuss them in the future.
These books have been written. Most people find these questions a chisoron in the book. I find them a maaleh; it shows the tremendous breadth of the series. Almost no other series would be possible to find such tiny details to ask from. Only Harry Potter has such a vast world that can actually have contradictions.
