OK so p03 is a DID system. g0lly was the original host!! she wasnt as innocent and childish as she is now. she was sweet, yes, but with a playful, biting wit. she looked up to the scrybes so much and idolized them, devoting herself to work as hard as she could to become one herself.
when g0lly became a scrybe, finally, she was in for a rude awakening. it was much more intense than she thought, and she wasnt expecting how much the other scrybes looked down on her. this, coming from her idols, was extremely painful for her.
it was at this point that she split the archivist, the photographer, and the unfinished boss. into them went the one-sided affection g0lly felt for the other scrybes; and now, unburdened by the pain of feeling hated by those she once idolized, g0lly pushed on.
being a scrybe was suddenly very lonely, monotonous, and stressful. but she couldn't just give up on something she pushed her whole life towards, could she? the weight of her responsibilities dragged her down, making her impatient and snappish towards those around her.
she hated who she was becoming. she hated her existence as it was. she didn't feel like herself anymore. she didn't want this life.
p03 existed to work. that was all he cared about. being the best, and getting even better. he didn't care about friends, or fun, or fairytales. all logic, all bitter, with a guarded heart buried so deep that he denied its existence. he took all of g0llys negativity and pain and formed it into a tool.
g0lly, in turn, reverted to almost a parody of herself. innocent, naive, trusting, with no responsibilities and absolute faith in the world. vulnerable.
p03 hated her. that vulnerability had gotten it hurt beyond what it had the capacity to handle. and so he pretended that she didnt now, and hadnt ever, existed.
