Wup! Noticed a second instance on re-reading: Harry then placed the geode in Luna's right hand.
Also on re-reading I noticed that Z said that he was part of the final fight against Voldie, and then traveled since 1981. Very clever! Now I'm curious how he did the time travel . . .
(I'm glad to hear that you've sent this to a second archive. I like Ficwad but it's not the most stable. Perhaps you could also put files at your Y!Group? I'd be happy to PDF them for you . . .)

Thanks. I'll doublecheck future chapters, at least through chapter 7
