Two things to remember.

First, J K Rowling is as dim as a Toc-H lamp. A stupid person who had one good idea and got lucky.

Two, Hermione is not an original character - none of JKRs' characters are. Hermione is a British schoolgirl reskin of Mr Spock.

Just so you know, when confronted with a importns chance, I always ask WWTDD? We all need our role models!
