I get walking around and talking but… is there a limit to how many people? I know with Poppi you level up Nopon knowledge by talking to people, but there doesn't seem to be anything like that for Electra, which makes me think it's a specific person?
I also just got my hands on the sealed core (Good thing that Big Problem can wait for six hours, ey?) so who should get it? I'm thinking Rex since he's my de facto heavy hitter and I understand this one's a fighter. I know about the whole shenanigans in chapter 8, but that's going to be a long fucking way away.
God damn, the way Niyah goes "Gimmie, gimmie!" when you pop a chest is adorable. 4 and 5 are kinda fun too.
