She is a hot mess, but she tries to be a good and semi-decent person. That isn't to say she is without flaw, however. In fact, she is riddled with flaws and insecurities. She doesn't mean to be, but she is. She hides all her human fallacies beneath a veneer of toughness. She might be sociable to a certain extent but when it comes to strangers, she tends to keep them at an arm's length until they earn her trust. Even then, time and circumstances have taught her to never put all of her trust in someone. In this post-apocalyptic hell, it's everyone for themselves and she is hyper aware of the fact. Her awareness of said fact often leads her to doubt people's motives and intentions.
