Ruby is Michael's little sister and is 51 years old. She spent her childhood growing up in his shadow. As a little girl she adored her big brother and followed him everywhere. He was kind but distracted. As she developed her own personality she discovered that no matter what she did or achieved she was constantly eclipsed by Michael's achievements and the low expectations of her parent. She was required to be a good girl, stay quiet and pretty and not cause problems. She was encouraged to focus on her looks and social abilities so that she would develop into a good wife for a wealthy businessman. There was no expectation of her to develop a career because, of course, she would marry well and be looked after by her husband.
Ruby bought into this role play for herself, although she was always aware of an underlying frustration and sense of confinement. She was not a rebel though, and met her family's expectations. At the age of 18 she married an investment banker. They lived a jet setting life an were generally convivial and she had two children - Brick and River - before he died in a skiing accident in Switzerland.
Packing her young children off to boarding school as she dealt with her grief - for she did sincerely like her husband - Ruby soon began to comprehend the freedom she could now experience. Her husband had left her insanely wealthy and, having already achieved all her familial expectations, she was now unfettered for the first time in her life. The freedom went to her head and she went a little wild. To help her move on, Michael introduced her to to A-list celebrity crowd. Ruby put her children to the back of her mind and partied endlessly in a maelstrom of frivolity, excess, and debauchery.
This is how she ended up in London at a celebrity fund raising ball. At the ball she met Edward - the most gorgeous man she had ever seen and one with a sense of devil may care that matched her own. They flirted, he courted, she fell in love, and six weeks later an intoxicating affair had turned into a whirlwind marriage.
This time, Ruby had married because she believed she was in love so it came as a devastating shock to realise that Edward only married her for her money and was planning to continue to party and womanise as if he was still single. Eventually Ruby thought to have a child with him in the hopes that it would settle him down. It didn't. Edward has pulled away from her completely. Perhaps starting this new theatre company will bring them back together and settle him down.
