Well, Harry certainly has a different take on things than we saw back in Chapter 2, where Hermione was saying that they just had some issues to work through. Harry seems to have taken her and the Wesleys expose on him as a bit more than 'a few things'.

Have you ever been in the middle of an argument where both sides are friends of yours and yet both want you on their side and not the others? I'm using that angle, the Weasleys are downplaying their part.
But now with more chapters up, I hope you're enjoying the story. Thanks for the review
