it seems that all the girls of RWBY have taken a massive step back in maturity - might that be an effort to delay dealing with the more adult stuff (emotional, not necessarily physical).

Don't get me wrong, I do think its a bit early for anything heavy like that but it seems an odd step to set their ages as late teens and then get them to act like little kids.
