Hmm, I'm not either. But she might not listen either in her current state. Then there's also the option of waiting for her in to calm down in the room. What does everyone else think?
Either way, if we do decide to give her space, maybe something like this?
[] "Okay". Start preparing to leave.
-[] "But your ignorance about what I need to tell you will kill you. You had almost died the day that we met. I'm sorry, but we're having this talk, and this won't end *gesture around timestop* until we do. I'll be waiting outside for when you're ready."
[] Leave. Preferably through the window, but if not, the door. Make sure the ring stays on her finger to keep her in timestop.
-[] If leaving through the window, get down using grief platforms or staircase. Leave them up as an invitation.
[] Keep a close eye on her through your grief senses to make sure she stays in timestop using the ring, doesn't get too corrupted, and that she doesn't move out of range.
[] Wait. Offer cleanses.
I really feel bad for dragging Homura and Mami into this. It's going to be frustrating. It already is.
