You were born into a loveless marriage. You were an unwanted child, you were not welcomed into the world, you were not loved. You spent your childhood being passed from nanny to nanny. You cannot remember your mother, the only thing you have of hers is an old butterfly clip. You've loved butterflies ever since you realized it was your only link to her. Your father is a cold cruel man only interested in keeping you out of his way and making money.
All you have ever wanted was to perform on-stage, to be amazing, to be loved by an entire room full of people. Because where else will you get all the love you need? Beck is nice enough but he can't be your entire family, your best friend and your boyfriend. Cat doesn't count, cat loves everyone, Cat suffers from exactly the opposite of you; she was loved too much, she doesn't want to let go of her childhood. You never really got one.
You've spent most of your life specifically going against your fathers wishes in some desperate attempt to receive some kind of attention from him. You got tattoos, piercings, a serious boyfriend, even enrolled in a school he didn't want you to go to. You are absolutely everything he never wanted, and he makes that perfectly clear.
You look after yourself at home, or use your fathers credit card to pay others to look after you. You do not have a family, you have never had a warm and happy home. You never realized until high school that your life was any different to anyone else's, you had assumed everyone was going through the same. It was when you met Beck that your life finally had some meaning, he was the reason to get up and go to school in the morning, he was the reason to be in all the top classes and to try to be the best. He was the only thing you had.
Yes you were a little overprotective of him, but he understood, and he never told anyone, you couldn't afford to lose him to a girl like Tori, she didn't need him, she was being selfish, you needed him, you couldn't live without him.
Eventually things did take a turn for the worse, your life was a stormy sea threatening to swallow you whole, Beck wasn't going to keep you afloat for much longer, what with needing to sing and dance and direct and act and be clever and popular and pretty, you also needed to cook and clean and shop and study and date Beck, it was all becoming a bit much.
So you starting becoming a little stranger, a little darker, you wanted pain, blood, bone, cuts, abnormalities, anything to keep your mind of you problems, you collected scissors and destroyed anything you wanted to, you became the dark tortured girl you had pretended to be.
At least you have something to blame it on, the apple never falls far from the tree, and your father has always been a horrible man.
