You were only an infant when Five found you amongst ashes caused by the apocalypse. He was only thirteen when he took on the duties as your father- raising and caring for you daily. When you were around 15 years old, he finally managed to crack the equation to bring you both home safely, but sadly due to a miscalculation, he was back in his teen body. But he didn't care much, as long as you were safe and finally had a proper roof over your head. You both moved into the Hargreeves mansion after Sir Reginald's passing which allowed you to finally live a peaceful life.
