Now, neither Ron nor Dudley are characters that are usually at the top of my list of favourites, but I adore what you've done with them, here! -In particular, Ron finding his aggressive side (after being bullied by Hermione), and Dudley finding his submissive side (after being a big bully himself) - it's very surprising, but works brilliantly, I think! I also like the fact that you've kept much about the pair of them the same as in canon, and have worked with it, rather than against it: Ron's large, protective family are part of the picture and have accepted their relationship, and Ron actually likes Dudley's big fat belly, rather than ignoring it. Great work :-)
