Looks like I had the right idea after all. I think strands of strong acid or a highly reactive alkaline metal would have been a safer tactic than the nano-wire garrotes, since Harry wouldn't need to spend the extra action to constrict, but apparently Eliezer had this planned out from chapter one and it was too late to change it (due to the silver line, black robes, etc).

What came after, though? Not quite as convincing for me. I can't believe that Harry was able to transfigure Voldemort despite the resonance cascade. I also am skeptical that Voldemort didn't have any passive shields up against stunners. And what the hell is harry even trying to do with this convoluted ploy with Hermione anyway? Hasn't he learned anything about trying overly-complicated plots?

I'd also be VERY concerned about Voldemort having backup memories stored in his horcruxes, especially since some of them are of the old fashioned personality blueprint kind.
