Maybe all of her meltdowns weren't only because of recent political events, but also because she knew Sleepy was joining and her trying to rizz Pippa was her last chance to convert the non-believer
In all seriousness, it would be truly retarded if Fishman did anything. Honestly, all biases aside, who would you rather have in your company? I know Clara is objectively talented, but she has already dipped out of 2 agencies, speaks more English than Japanese letting her genmates flounder when she should be doing collabs to boost their exposure, possibly needs paperwork to stay in Japan, has been committed to a psych ward, and can't shut the fuck up about her opinions that would be disastrous to a mainly young male audience if they were to break containment. Versus an ESL with edgy humor that learned English just to stream, always has a positive community supporting her, has been with Phase longer, and has been noticed by Hololive talents.
Can you imagine how many talents would be pissed off if Panko left? Without naming them all, I think a lot more would be mad at that than Clara leaving after she tried to stir shit up.
