Pyrrha and Nora

The Judgemental Critter brings up that Pyrrha and Nora's character arcs center entirely around the feelings they have towards Jaune and Ren respectively. Even when the story has them separated and engaged in potential to have other narratives, their arcs go back to focusing on Jaune and Ren, to the point where Nora's entire character arc in Volume 8 is about figuring out who she is WITHOUT Ren.
