An idea: We're discussing lethal magic, of the sort that even Quirrell is unlikely to have taught. Has anyone checked that she even knows the Blood-Cooling Charm? She reads a lot, and Quirrell is unlikely to have left a hole that obvious in his plan, but this seems like something that may be worth checking.

This occurred to me, but Hermione really shot herself in the foot by publicly demonstrating the ability to successfully cast a charm above her year level on the first try, from nothing more than having glanced at the instructions once.

Plus, just from naming conventions I would expect that spell to have non-lethal uses- it's not called the Blood-Cooling Curse, or even Hex, but Charm. Maybe it's a treatment for heatstroke, or the counter to the Blood-Boiling Curse. In any situation other than under Hogwarts' wards, a Charm that takes six hours to kill an unconscious first-year isn't that big a deal, compared to, say, Levitating them off a cliff and dropping them.

True, but it's a question that might get asked under Veritaserum.

(That said, we are talking about Hermione here. She can probably learn the spell from the false memory of having cast it once. So this test isn't likely to be conclusive.)

Exactly. Which, while awesome, is not especially helpful in this one particular case.

Spells that extract the history of spells casted using a wand are canon, afaik (or was that just the most recent spell?)

I would expect they were casted on hermiones wand and the usage was confirmed.

Thing is, it only checks the most recent. Any minor spell cast afterwards clears the prior incantem, so a different spell showing is not going to count for much. And they never actually said that they had that piece of evidence, which they certainly would have if they'd known.

We only saw it used to check the most recent spell. We don't know that it can't go further back, and in fact in fanfics it often can go through the recent history of the wand.

But that's not canon IIRC, which means that it should be assumed not to be the case unless EY says otherwise.

The Priori Incantatem effect of the brother wands meeting certainly seems based on Priori Incantato (though why was never explained that I could recall) and that one certainly did go back further than just the last spell.
