Yes, absolutely. If we're going to be calling her, one sentence of minor subvote is nowhere near enough guidance to the approach. Riona is Important - quite possibly more important then Madoka or Homura are to truly breaking the system.
While I agree with your conclusion, because being polite is important here and Mami
just noted to us that telepathy is not always the best way to introduce yourself, I disagree with your reasoning:
For one, it's strikes me a bit of hype. What we know is that Riona manipulates the soul, that she will be is interested in
something we try to do, and that she is strong. Not much more. We've consistently had problems with conclusion jumping. See the recent "Oriko's dad killed her mom" thing.
For another, however, it's quite clear we have many of the
parts of dewitching and changing the system. At this point, if we can open communications with Aurora, whether it's one via some communications device or just giving her a body to speak with us with, then I suspect that's the enough to net us a very rudimentary form of dewitching. A form that will probably take ten man-years of work to input ~20 million ccs of magic, but one that I think is very probable
to work. After that, it's just a matter of refining the process, ensuring there's no memory loss, dealing with any remaining trauma, and building a proper body.
It's also possible that Godwinson's hypothesis that witches are truly separate beings is correct, but even that is one more issue deal with, rather than an insurmountable obstacle. And may just fall under the "memory loss" bit.
Of course, dewitching isn't enough to enact permanent change on it's own but the other missing piece there is "just" some alternate means of cleansing. If we can devise something to both pull out grief out of gems and seeds and either replicate itself or be replicated by the work magical girls? As long as it takes less magic to make than the amount it can cleanse in grief then that right there is a working solution.
Riona's aid will certainly be
useful, but we aren't ten thousand miles off from having any solution at all without her. If anything, I'd currently expect the most important help we have is
Sayaka. And not just due to copied powers: If the current stage of things is necessary then the base mechanic of her power and the gems she creates might be able to help fill clear seeds orders of magnitude faster than the slow burn we can currently expect.
Usually that's, like, booping a dog's nose, not doing weird abstract stuff to the most valuable item you ever have or ever will see.
Well, we are talking about teenagers here and teens aren't super well known for reverence.
That said, this isn't something I expect would happen before clear seeds were spread fairly widely. It's far more likely that someone knowledgeable, like Niko or the Fukushima group would attempt to inject magic
willfully in some attempt to bring someone back.
In fact, I wouldn't put it past some group with a recent loss to hand us their friend to make into a clear seed in an desperate attempt to save her.
Hmnm.... One thing I
do think we should test is what happened when Aurora is left near an enchanted object that isn't grief. Because if she pulls the magic out of enchanted grief,
do we also have to worry about clear seeds seeds pulling it out of other enchantments? That's the sort of thing that could get interesting for Fukushima given Yuki's enchanted building focus.
Well, even if that's not the case, I'm in favor of telling people what's up for a simple reason: It may or may not be super important as
safety information, but if they ever find out about witches, especially after losing someone to a witchout, then all of our dire warnings suddenly turn around and become an
instruction manual.
That's half the problem, the other half is Sabrina's actions change Oriko's visions so whatever prediction Oriko had may be outdated by now.
Her visions being outdated is pretty irrelevant to the argument posited. If it was impossible for her to see changes to herself, then it's possible she never would have seen such things as herself using healing or enchantment before she actually learned those skills regardless of our intervention.
