Wow! If you're gonna do it, do it right! I believe I read something like this some time ago, but Harry used a hypervelocity missile from a space station. A well writ story, sez I!
Those wards had to be ungodly strong, to contain that sort of damage. (Something on the order of a thousand multi-megatonne bombs going off.)
I didn't understand why Harry even asked Hermione if she would satay with him. He knew he was going to die, so why ask her to join him in what would have been pure suicide? I do, however understand why he asked (Ordered!) Ron to care for her.
Well done! Alorkin
Thank you, sir. It's been about a year and a half since I wrote this one. I think I originally said Harry split his time between carving runes and being a bathtub chemist,(What you can't make up in quality, go for quantity) but that might have ended up on the cutting room floor, as it were. Heck, it's even been a while since I've read this.
If Hermione had agreed to stay, things might have turned out differently. She may have found the answer that would rid him of it. If she had agreed, this plan may never have happened. But he had to give her the choice.
I think that if she knew what the result was going to be beforehand, she would not have made the decision she did. Harry didn't want that to influence the decision. He wanted honesty. She chose, and he immediately enacted plan 'B.'
It was the Gryffindor thing to do, so the ultimate Gryffindor did it. He also succeeded in scaring the living crap out of Prof. Sinestra and Minnie McG in the process. I think Sirius and James would have loved the prank value of it.
Maybe Harry found out, maybe he didn't. I'll let you decide.
