I believe you have a problem with transparency here. You did not adequately link your revelation with the refutation of your previous thoughts. It may seem obvious to you that “squeezing the future into a narrow region” means that your old ideas “would have converted its future light cone into generic tools.”
And, no, I do not think it is reasonable to ask me to read everything else you’ve ever said on this blog just to figure out the answer. Perhaps the explanation is too long for this post, but I would at least like some links.
I think you are erring when you assume that these are Voldemort’s plans. They might be, but I don’t think they have to be. The story seems to have deviated quite far from the original story.
In fact, my reading is that Quirrell may actually be some good guy, destroying our expectations from the story. I mean, has his turban even been mentioned?
