The Lumi thing is really weird to me, and I'm actually specifically talking about on Lumi's end. What if - and hear this out - Pippa actually has a reason for saying she didn't want to do yabcast? That it isn't 'her fault' per se, more that she just doesn't want to for some kind of actual legitimate reason? I don't like to rrat very often but it is SUPER WEIRD to me that Lumi semi-often brings up Pippa ignoring her publicly despite them being in the same company that has managers and can very obvious mediate conversations like this IN PRIVATE. The fact Lumi brings it to the public leads me to the thoughtprocess that it may be a transparent attempt at communal strongarming at this point, to force her to respond because company unity optics and etc.
Idunno, this sort of thing just wouldn't surprise me at all. People have said this has happened with Tenma before but I can only really remember a handful of times, and I also recall Pippa having said that her and Tenma sometimes have explosive fights where they don't talk for months only to make up way after the fact - hence potential explanation for that. Pippa's very clearly not as bad with DMs from people she knows as she used to be, and I am lead to the conclusion the Lumi thing surely has a reason. And not to get too rrat-flavored, but Lumi having the 'lemon whore' / 'list of crimes' running gag is literally the perfect way to mitigate nearly any and all criticism or speculation such as this. Bringing up these ideas will invariably be met with "HAHA SCHIZO! LUMI LIST OF CRIMES STRIKES AGAIN!!!". It's honestly a brilliant strategy.
