Rose was who Pandora USED to be, before she got fed up with the world/society... out with the fancy dresses, long hair, and being 'respectable.' Now she'll tell you to "fuck off" right to your face and be a generally rude individual... A curse of being sensitive to disasters, now that the world is basically one disaster after another it's her only way to handle all those stressors, that and probably being inebriated in some way...
