Cedric Diggory, yeah. I don't think you should get into it with them. Judging from what I know of the books, they'll end up fighting it out, going through some kind of silent treatment/let's glare at each other phase, then they'll subtly start talking again. It's what they do. I don't like the idea of Adam being mixed up in their arguments especially since I don't want Ron giving Adam a hard time, but it's not really our problem. We've got bigger fish to fry right now. Thanks for that, by the way
