I know this is way early but i fell I should comment. Ron is only ten and he said something hurtfull. That does not make him un-redeamable. Everyone makes mistakes.
That being said. This is a great story so far, Its a little fast but I like that you skip over the parts of cannon that everyone already knows.
There are some people that you just don't like. Harry just doesn't like Ron. He takes personal offense to idiocy. I'm not trying to make Harry into a saint (God maybe, but not a saint). Thanks for the review.
