I think poking Oriko isn't necessary. I don't think she can offer Rin anything. If anything, it's to assuage our own fears that 1) Akiko isn't going to witch overnight and 2) that the disaster we came here to avert was actually averted. If you want to add it, phrase the vote like that. And also remember we're trying to not give any hints of precog to anyone.
Anyway, just a few very quick refinements, because I don't want to charge in and relax Oriko's house arrest tomorrow while Mami's at school without consulting her first:
[x] Us doing anything can only make things worse.
[x] Trust in Rin. She'll call us if anything changes.
[x] Update Chouko on the situation
[x] On the way home, bring up that Kirika deserves some serious thanks for everything she's done for us today, and that Oriko saved a lot of lives and blindly trusted us with her girlfriend's, seeking Mami's opinion.
[x] Go home. Drop Kirika off with Oriko, cleanse Oriko & the seed you left her, then go home.
[x] Collapse into bed, huggle the Mumi.
