Harry- not the sharpest tool in the shed...
Something I have long expected about Potter is his small problem with exercising logic in the brain department.
Not being able to get the middle part of the Sphinx's riddle in GoF- one of the oldest tricks in the book- wasn;t a great advert for him.
But more recently, Harry rules out his father owning the HBP's rextbook because it was published 50 years ago.
In retrospect, that looks like a pretty dumb reason to have excluded that possibility, yes? Mind you, the Prince himself must have been poorer than we might otherwise have expected.
Unless the Conspiracy theorists wants to make anything of that, of course.
Anyway, does anyone feel that JKR makes him deliberately not all that bright so readers can feel superior by comparison?
