[X] Reaction: Disappointment. Tone: Very serious.
-[X] Calm down.
-[X] Offer cleansing and cleanse yourself.
[X] Look Riona in the eyes. Override interruptions.
-[X] Show her Aurora.
--[X] Ask if she sees anything unusual in the Seed.
--[X] Briefly explain your dewitchification experiments.
-[X] When you heard about her from Nadia, you were really happy, because an expert on souls could make a huge difference in making this dream a reality.
-[X] ...but you can't work with her. Not while she continues to enslave souls. You'll try not to judge, but you're not going to condone it.
[X] She came here with the intent of killing another false Grief controller. What does she intend to do now?
-[X] She went out of her way to present herself as a villain who enjoys enslaving others. You don't intend to buy into that provocation, if that's what she was hoping for.
-[X] She is free to stay in Mitakihara as long as she doesn't cause any trouble.
-[X] Your offer remains open, if she changes her mind.
[X] Be on guard for any aggressive moves, and be ready to signal Mami and Homura if it looks like Rionna is going to attack.
[x] Keep Rionna talking.
-[x] Flat out tell her that you want her help with dewitching, and that you're offering her the cleansing she wants. Why is she so willing to leave?
[x] ABSOLUTELY DO NOT LET RIONNA NOTICE THIS, KEEP YOUR EMOTIONAL REACTION TO THIS MUTED:
-[x] Calmly message Mami with grief, requesting that she not react and contact Homura for timestop, please.
--[x] You need to discuss what Rionna has said with Mami, Homura, and Sayaka to decide what to do. You won't commit to any action without that discussion first.
---[x] Keep calm, do not commit to hostile action against Rionna in your mind.
[x] You flew half way around the world to find a real Grief cleanser, and you're just going to leave? No. You came here looking for something. Well, so am I. Let's deal.
[x] I'm trying to figure out how to turn a witch back into a person. The Clear Seed is the first step. They have thousands of times the capacity of regular Grief Seeds. One of these can keep a magical girl clean for centuries. And eventually we hope to enchant something that will do the job without needing souls at all. No more witchouts. No more used Seeds going into Kyubey's back for him to do god-knows-what to. No more need for girls to put themselves through this hell of hunting and fighting to survive. We can all just live like real people.
[x] When we no longer need Seeds to survive, we can start helping them, too. We've already gotten some small results from injecting positive emotions into the Clear Seed. Your soul powers might be the key to making this back into a Soul Gem. [x] You came here looking for a charlatan, a dragon to slay, but I'm not your enemy. I want to help people. Ask Nadia Bennouna, she'll confirm that I'm for real.
[x] You fought the false Grief Cleansers because they were witching girls out. We don't want anyone to witchout either. We can make a world where no one does, ever again.
[x] Please. Help us.
[X] Sigh, relax your visible tension, maybe slump a little bit.
-[X] "You're not very easy to work with."
[X] Explain and demonstrate your power
-[X] Pull grief from your soul gem, float it around, make a few shapes. Perhaps a flute that starts softly playing music?
-[X] Pull a little bit of grief from a grief seed, just to prove its possible
--[X] Explain that floating grief is easy to manage, especially given use of a 4th dimension of space. If the cloud ever gets to be a bit too much you can just shove it down Kyubey's backhole. We can demonstrate this afterwards if she'd like.
[X] After power explanation, move on to explaining your goals.
-[X] Emphasize your desire for magical girls around the world to be able to live normal lives
--[X] Ultimately, you want to break Kyubey's wretched system of grief and suffering, and replace it with something better
---[X] Some enchanted artefact that can absorb grief, or the proliferation of clear seeds or something that'll ensure magical girls can live long and peaceful lives, witches can be slowly but surely removed as a threat, and maybe Kyubey can even still accumulate grief for his anti-entropy efforts.
[X] Now Riona knows what you can do and what your goals are. What's her place going to be in things?
-[X] She can choose to help Sabrina with her powers, with her experience and very different perspective
-[X] She can choose to go home in peace and deal with her own shit for however long it takes for Sabrina to fix things and bring infinite cleansings all the way to Ireland
-[X] She can, for whatever reason, oppose this. Preferably with logical argument rather than sudden hostilities. Maaaybe don't mention this? Let it go unsaid unless she comments.
--[X] Whatever her immediate choices, know that enslaved and possibly suffering shades of the dead won't be tolerated forever. That kind of shit belongs in Kyubey's system, not ours.
[X] Discretely call Mami for an emergency timestop meeting with her, Homura and Sayaka
-[X] Get them up to date with the meering with Riona.
-[X] Discuss the next course of action
