0:16:57 Was I the only one that was just as freaked as Twilight when Fluttershy mentioned that there was a Principal Celestia and Vice-Principal Luna? Also, if they are the principals, but Princess in their universe, shouldn't they be the presidents of this country? Or the mayors of the city?

Also, if everyone has counterparts, how old are the counterparts of Luna and Celestia supposed to be? Aren't they like over 1000 years old? This world's rules makes no sense!
And MORE LOOSE ENDS!
