Draco/Ginny fanfictions are awful. I don't think I've read a single one that sounds plausible with those two. Beyond dominance, which I doubt JKE would ever resort to, they'd never happen. And shouldn't. I wouldn't mind Harry/Ginny so much, but I don't want that to tear Harry and Ron's friendship to shreds. Rofl. And as for all the slash 'ships? Oy.
Well, I'm glad he got away with it.
