I don't think she counts non-specific plot things without identifying details (like how we all - ok, the vast majority - knew that there was a significant you-know-what in OotP, but not names or places) as spoilers. So I already know one or two minor things like that for DH, which is annoying, but I've reconciled with it.
But Glen - very restrained of you. Equal number of stabs I don't think is enough. A number of stabs equal to the worth of the spoiler, perhaps. I mean, you could only get one spoiler, but it could be the biggest, most important point of the whole book.
Though I suppose it could be met with one stab. Through the carotid artery :)
