We're not.Best not to talk too much about the past if we're pretending to cover for a precog who only sees the future.
"I know our potential enemies here," you say simply. "I'm not a seer, but... think of it as something like clairvoyance?"
Except we're saying that because we're not bringing up Oriko. Look at the vote that got us hear and the lead in to that line:
"I..." you hesitate. "I know a few things, and..." You glance at Oriko. You don't know how to tactually break it that she's a seer with malfunctioning powers.
"Oh?" Saki asks. "In what way?"
"I know our potential enemies here," you say simply. "I'm not a seer, but... think of it as something like clairvoyance?"
People do dumb shit all the time. And for all that Sayaka and Kirika call it stupid, we have exactly nothing on-screen from Oriko, who's the only one that's actually seen how these things will play out in this timeline. And I note that @Firnagzen continues to remain totally silent on how much we discussed with Oriko and what opinions and information she had. Which is remarkably annoying, if it's not simply having missed my earlier questions about it. Like, I know you're good enough that you don't need to be playing information-hiding games and refusing to answer questions that we should know the answer to.@Vebyast
I'm not sure "explain Kanna to Niko" is at all the right approach, given Firns fairly unsubtle hints tha Kanna's motivations are way less pant-on-head in his interpretation than in canon.
"Gently and supportively raise the topic of her wish with Niko. You have reason to think it might be relevant," is a lot closer to my take on it.
Or they put it in a doorway, hallway, or other chokepoint.A memory editor with a "several meter" range is basically useless and we can ignore it. Unless Firn has a very different idea of what "several meters" is than we do, defeating it is as simple as not standing in a single hugpile the whole time. Maintaining a minimum separation-between-furthest-pair will ensure that some people will remain outside the area of effect and be unaffected. Unless, of course, our opponent has super-science and has already improved the performance of the device by an OOM or more.
A tall order.
Then we walk the rest of the way through the door, see a bad guy holding a clear seed, and go after her.
