This is an idea I've had for quite a while now that may or may not happen in the show in the future, and that would be a fight between main characters. No I'm not talking about a sparring match or some sort, I mean actually fighting each other to kill or something. Similar to how Captain America: Civil War breaks out, but not as.... team biased. More on who agrees with what more.
A decision may come whether or not someone wants revenge or not against Salem or Cinder for events like Penny and Pyrrha's death. I could imagine Jaune, Blake, Yang fighting for revenge whilst Ruby, Nora and Ren think more... thoughtfully and try stop them.
Another possible scenario that may be more likely to happen would be between Blake and Yang (Assuming Yang actually does recover somewhat).
Whilst the idea or thought may sound a little stupid, it was just a thing that popped into my head whilst watching Captain America Civil War.
