Well, we have to say something to Anri... Polite explanation of what we're doing and where she'll be staying for the near future? Possibly start with a "Me," agreeing mildly, as opposed to enthusiastically or hamming it up- because while those wouldn't win any points of diplomacy, I'm not sure what else she's expecting with a "
You," like that, really. A mild agreement in response to what she said to start the dialogue, and then moving onto what we want to say, touches the minimum requirements for a back-and-forth exchange, rather than either seeming mocking with the hamminess or just outright ignoring her and talking over her like she's not there or worthy of response. (Edit after I got to actually making this look like a vote: Should we put in a line to be careful to watch and make sure no accidental Witchbomb happens? Because Mami is in the room.)
Edit while writing:
@Kkutlord has a good point. Although we'd have to provide a good reason, at least nominally, about why we're giving the prisoner a Clear Seed. Although, I guess she's technically made a deal to stay in custody, right, so it's not
quite as much of a concern as, say, giving Iowa a Clear Seed if we had any of them in custody. Still.
Then I think the vote in abeyance is fine... Maybe make sure to ask Oriko about the graffiti after Yuki and Anri and Rin and Sakura have left, since it's very clearly a separate side thought that I don't think belongs even in the tail end of a business-type meeting, even when everyone's trying to friendly-talk.
Enchantment practice... I'd say having Madoka and Hitomi come along is probably fine, since we want to keep them in the loop and this is a good time to unwind-ish and update them on how the talks went. And everyone together like this will be a generally more reassuring feeling, even unconsciously, for the discussion, just because everyone's together and
safe together, probably being the largest show of force in one place for many miles around, and not worried about the new friends and having everything handled. And they get to see everyone being productive, and maybe we can bounce a few thoughts off them about how to address the meguca-doing-business-things thing, and get their perspective. Keeps them involved, and it really is useful to have as many eyes out for ideas there as possible.
We're working with Mami about trackery-things. What is Sayaka wanting to be doing, again?
Probably ask Homura and Sayaka for that talk after enchantment practice. Since we're planning to work on tracker-y things and tripwires, yeah? So we'll have the full measure of what we have to work with, not just "skills we're going to be working on tonight", to attempt to convince them with. What time is it that we're doing the enchantment practice, again? Like, is this before dinner, then work until dinner, then break to whatever we choose for nighttime activities? Because if that's the case, then probably ask to talk to Homura and Sayaka after dinner, and privately ask to speak to Homura a bit before Sayaka. (And maybe tell Mami privately that we're going to be having this conversation, before we actually start the dialogue with the two of them to plan having it, just in case she points out any glaring flaws in our approach...)
Approach... Homura with the "now we can track them everywhere, and if nothing else, letting them out to get groceries with an explicit tracker on them that each of the rest of us can check whenever we want is probably better for upkeeping their usefulness to us, and now viably safe to do" argument is probably the best way to go, yeah. Reassurance is the goodness, when one is paranoid about things that can go wrong when you're not staring directly at them. I definitely know the feeling.
For Sayaka... the bit about how house arrest isn't really being helpful anymore... did we ever explain fully what happened with Oriko, what she saw, and what happened with her dad and everything? I dunno, I feel like a full picture of "what was up in the Mikuni house", er, possibly a bad choice of words, would be good for getting Sayaka to seriously consider our arguments. After the whole "Homura had a number of good reasons for being unfriendly" thing, I feel like this Sayaka is probably more willing to look at the why of people doing things, and evaluate with that in mind. Though yeah, burned down house is still rather, a lot.
Maybe want to have the explaining the everything to Sayaka separately from Homura, just so it doesn't seem to Homura like we're trying to apply those arguments to her and pressuring her to care about them by implying her reasons aren't good enough? Not even remotely what we mean, but the nagging parts of the mind do catch on that sort of thing. And also, small separate Sayaka talk will keep from giving Sayaka an unclear evaluation of Homura's thoughts on the matter, which she'd get by looking for Homura's expression or lack thereof if she were there for this explanation. Eh, not actually sure this is a good idea, or what order we'd do things in, though.
... I wonder... Not really something to bring up now, but it came up a bit in another PMMM quest recently- does Homura just sort of raid doomed timelines for everything that's not nailed down before she leaves, sometimes? Be interesting to know if she has any of Sayaka's destroyed stuff from another timeline, not for now, but if ever explaining everything is a thing that happens.
