Originally posted by Diamond~KissesIt is a "what if" thing, so who cares why she would die, she would just be dead. Second, I would rather hope they don't publish a unfinished story full of notes and stuff (at least for a couple of years), why? Because one, it would get sold more that way and help support JKR family and two, it would make it even better.
WHY would she die? Randomly?! I don't think so!
Also, as Samura said, She probably has notes and stuff like that, it would be released as an unfinished story.
Also, as I say, she knows what the ending is, right? So her publishers would publish that.
