How is getting kicked out of the group of little consequence and why does it have to be the only consequence for not going along with the leader? You are assuming too much on stuff we know next to nothing about.
Yea I meant the inverse(and edited the original post), that if they're going to have her disobeying orders as such, then there should be consequences like getting kicked out of the group but I doubt they would go that route as it would probably be too much work and they'll use the excuse of 'kids will be kids' in game.
