2 cents from a felon who knows about bad decisions:
I don't think this is gonna go any further than it already has. I don't think any other member is gonna spill the beans. I don't think Rushia is gonna sue. I don't think she'll divulge anymore information.
I don't know if Rushia is actually crazy but I doubt it. She's just a woman who had a slight screw up, over panicked, made things exponentially worse by trying to take responsibility and fixing it herself and doing it very poorly. She made a mistake and it cost her her job. Her Gen mates are probably hurt and pissed because of how badly she screwed up and in such a stupid way to boot. It makes them look bad, it makes their company look bad, and just the general frustration of Rushia either not going to them first or ignoring their advice and taking it on herself. Rushia does not get to ride out into the sunset like Coco. She gets erased like she was never even there.
It's sad but it's life.
