Thoughts!
... Rionna, did your name change spellings again while I wasn't looking?
Also, the first thing that comes to mind reading over this section is Heterodyning at someone spark-wise.
The description of what happens to the magic she's trying to throw at us implies some kind of imperviousness or incompatibility- Rionna's 'annoyance' seems to imply that this is either not unheard of, or she's given up being surprised by our bullshit. Not enough information to tell which. If our immunity isn't unheard of, I'd be interested in knowing about previous cases.
Also notable:
She wasn't trying to shade us. She can't access her shades or their powers from inside our Sphere.
That means the mind trick she was trying to pull on us is her magic, some of her intrinsic magic. She failed even setting off her first attempt at a thing, which may have been something related to her shades that our Sphere blocked, but the second thing started to work, was an effect we could feel. It just didn't work on us.
She's got some unknown brainjacker-y power, is what I'm saying. Power or constraints are unknown, though it appears to be either not instantaneous, or she knew well enough to try and gather up all her strength to throw at us particularly. Still didn't work, but even if we assume she's limited to short, focused commands, she officially cannot go anywhere near Homura at minimum, and preferably anyone else, for any length of time that would give her time to gather up her power in this regard. If it's not limited to short commands, that makes it worse. Until we know she can't just command people, this is a Big Issue and can we call in our anti-brainjacking-measures? Didn't, uh, Umika, of Asunaro, have something like that with her book, or whatever, which we used because of Hijiri and Anri?
I appreciate that the #milesgloriousus player chat was actually on the dot about screeching about brainjackers and shit. Just, it's not us who's a brainjacker, it's Rionna, and vetting by Nadia don't prove nothing. Clearly we keep shitpost speculating in the IRC as though we're random ass meguca hearing about this shit- we might unintentionally hit on all sorts of secrets ahead of time!
The fact that she's only used that power to try and shoulder her way out of the Sphere does give her some points. Some. Not that that's a high bar at this point. I'm concerned a bit about Nadia being compromised now. And if Rionna tries to push things using brainjack, then- Then we'll have to deal with that too, I guess.
I highly doubt that rezzing Riona's sister is a required component to fix things, the process of grieving and mourning and whatnot being a thing that we could eventually push for. That's fixing too, in its way. We need a foot in the door, though, and our intel about resurrection attempts may be part of it.
I'm not sure that Homura's wish (whether we take the time-travel-only, or the slider-only, or the complicated-time-slide-mess, interpretations of her powers) is the thing to be using to analyze resurrections with. The mechanical processes involved in either sliding or timecycling seem like they'd be wholly different than those involved in enacting a small local change of entropy and soul retrieval for a single organism.
Wait when was this? Supplementary material? I've never seen this one cited before- where from? That's a big thing evidence-wise that would be good to be able to point to, can I have a link for saving?
Wasn't that not a wish resurrection, though? I'm not sure about the others or their contexts, but Kazumi specifically was a Science! resurrection, wasn't it?
