So... Oriko closed the door to buy Sayaka time?
This really shouldn't be a surprise. It's very possible Oriko never intended for anyone to die, and deliberately set things up that way. It's always been a possibility.
The real question is
why she resorted to such risky and extreme measures in the first place. We need to force her, in no uncertain terms, to tell us
exactly what "is to come" that could justify this behavior, and how any of this behavior is supposed to make the difference. Then we can go about proving her thoroughly wrong.
We need to press into Oriko that, A) speaking in riddles is OVER now, B) Her plans have been thoroughly wrecked, and even if they have not yet been, we're going to ensure that they are unless she convinces us to do otherwise, and C) if her precognition was perfect, she wouldn't have been torn to swiss cheese and had her head blown off--so putting a bunch of lives in danger is something she has to justify
without relying solely on 'my precognition told me so'.
We should also impress upon her that not only is her life on the line here, but so is Kirika's. If Oriko really cares about her, it's more leverage for us.
1) Dragging the heavily wounded Oriko to the hospital will be painful, implying more cryptic answers = more pain.
2) We literally did what Oriko asks, your move Oriko
3) Separates Oriko from Kirika
4) Abusing timestop so its really just a painful trip for Oriko's "benefit"
5) More grief marbles!
6) Sayaka can get involved, good or bad idk
7) We can take out that Witch, sure whatevs
8) We can get some painkillers and bloodpacks? Idk
It also separates us from Mami and Kirika by a large distance, which could be a problem if timestop suddenly fails or is no longer a viable option to the situation. If Kirika witches out without us there to cleanse her gem or provide Oriko as reassurance, Mami is left there with a broken arm right in the middle of a witch barrier--formed from a magical girl whose powers were antimagic AoE. Not a good situation. It's also all unnecessary, and there's no point in resorting to crude torture so early on, when she might be fairly cooperative. She's only had the chance to give one answer so far, and she's already feeling like death.
