I could see Josh butting heads with Logan in training if only because he really doesn't want to be there on that team and he feels useless most of the time. But of course Logan is intimidating as hell, so he's not too disobedient As I'm sure Logan isn't thrilled about having to train them either so yes XD
And Jono and Pietro. Probably not a lot going on there since Jono is a loner as well and Pietro is just Pietro. But I'm up for anything! :D
