Insofar as we give her any control at all by forcing a confrontation at her private residence where she didn't want us in the first place, and demonstrating that we can find her anywhere in almost no time at all, and deliberately meet her in an emotional state where she isn't mentally prepared to deal with others.
Urgh, when you put it like that... Kind of wish that we could just leave her be. This really bites.
[X] "She used up the Grief Seed. Explains why she didn't even want to think about going hunting with us... Hopefully didn't mean to go hunt alone in order to show up with a Grief Seed tomorrow."
[X] Check if there's more pieces of paper scattered around, or in the trash. If there are, check in case they're suicide notes, or something similarly bad.
[X] If you don't find anything too bad, leave everything like it was, re-lock the doors and go stand outside her window, standing on a flying carpet. Ask Homura to end the timestop and knock on Ono's window. We're gonna have that talk, so she's got two minutes to either come outside or invite us in.
-[X] If there's no window for this, use telepathy instead: If she doesn't come outside, we're knocking and speaking with whoever we need to in order to talk with her.
I think we should be able to pretend we didn't come in at any point.
We're actually going to go look for suicide notes now?
Also, maybe we should ask our friends to chime into the conversation to help talk to her or calm her down? She was being kind of bratty before, but now she's probably going to be a lot worse.
