yekke2:
This question occurred to me whilst mulling over PAA’s excellent question. However, I focused on the actual question at the time, but came up with the exact svorah you mentioned, that the aim of the conqueror must be to defeat their opponent fully, as opposed to any schoolboy duel where both sides are aware that any victory is temporary. I anticipated having to address this as I attempted to deal with the issue about how Harry knew his plane would work, as I wrote in the brackets ‘not that there aren’t any valid questions, simply that the process stands up to scrutiny’. The ‘valid questions’ in this instance would refer to the process of defeating an opponent, and why this would not apply in many other instances of duelling and the like.
As a general point, yekke2, as I said above, what really troubled PAA, and is currently bothering me as a result, is not how the process worked, that it applied to other wands under the defeated opponent’s jurisdiction. That is not the issue at hand, although you have addressed it superbly. The question is how Harry knew the process would apply to a wand he did not physically conquer.
