Millie suffers from Dissociative Identity Disorder, which means she has at least two distinct and relatively enduring personalities. Along with Borderline Personality Disorder which the essential features include a pattern of impulsivity and instability of behaviors, interpersonal relationships, and self-image. Because of her disorders, Millie is prone to being hot headed, stubborn and occasionally unreasonable when she gets in that negative mind space. Usually, she's quiet and keeps to herself, not speaking unless directly spoken too because she thinks that people don't want to hear what she has to say. She can often be caught staring at everyone else, watching what they do and how they act around others, making her seem like a bit of a weirdo by others. However, when she's in one of those good moods, she's outgoing, sarcastic, flirty and quirky. To her, laughing is the best thing in the world even though she doesn't do it much. She has a bad tendency to fall for anyone that treats her with even the slightest bit of compassion because of her inability to truly understand personal and social interactions. However, she's very understanding of other people and their problems, and will be there for them while completely forgetting about herself. Considering herself extremely flawed, Millie is often depressed because of her own thoughts but hides it from the public so she doesn't feel like a burden to people. With a contradictory personality, her view on how others see her is: They either love to hate her, or hate to love her.

Biography

Millie is the only daughter of a human father and supernatural mother. Her mother was a Banshee, one that lured her father to her with her ethereal beauty. A one night stand turned into a pregnancy and as a Banshee, her mother couldn't raise her. In that case, Millie's father was left to raise her. Even though she has a rather unusual lineage, Millie's life was as normal as any other kid's. While she never knew her mother, she never needed too because her father filled both roles for her rather effectively.

At the young age of eleven, Millie was the unfortunate victim of a car accident. Clinically dead for two minutes, when she was finally revived, it was clear that something wasn't right with her. What she never told anyone was that while she was dead, she met her mother for the first time. Besides that fact, dying seemed to fracture her young mind, or perhaps it just jump started an already existing mental illness that just hadn't manifested yet. Either way, the psychologists at the hospital told her father that she displayed early signs of Borderline Personality Disorder.

It wasn't much longer after that, that it became apparent that she was displaying completely different personalities. Admitted to a mental hospital, she was often visited at night by her 'mother', who taught her of her lineage and some of the powers that she possessed because of it. However, instead of being excited to finally be in any form of contact with her long lost mother, Millie resented and disliked her frequent appearances. After one particular night, where she attacked her mother and told her to never come near her again, she became terrorized by night terrors. For years it went on until the already mentally fragile girl couldn't take it anymore. An attempt on her life fractured her mind even more, making her other personality that much stronger and switching more frequently.

When she was finally discharged, required to be home schooled for a short period of time because of her long stay in the asylum, she told her father of what happened. Showing him what her mother taught her, he requested her attendance to a school that caters to unique children. After attending the school for a few months, she was able to make the student council where she manages all the club sign ups; which was good for her because no one has made a club so far. She hasn't made any friends and keeps to herself regularly. Her blackouts have happened a bit more frequently, but she doesn't bother anyone with them.

When she finally graduated high school, Millie tried her hand at college for a few years but found herself constantly bored half way through the year and would end up failing her classes. It was during a science class dealing with bioluminescence that she was terrified at the realization of her ability to suddenly manifest balls of blue fire; having been pointed out by one of her classmates. Locking herself within her dorm for weeks until the balls of fire stopped following her, Millie felt far too embarrassed to show her face to her science class and dropped out. After that she decided on trying to get a job. It took far longer than she ever expected and eventually had to move back in with her dad in order to keep herself from going homeless. Eventually, dissatisfied with her life, she asked her dad to lend her some money so she could move and try a whole new life in hopes that it would be better than her current one.
