She remembered her mother, putting her to bed with a good night kiss and a soft "I love you". She remembered feeling safe and loved in her arms.
Then her mother left. From one day to the next she had lost the stability in her life.
Life planetside and a career in the political society of her home planet was more important to this woman than motherhood and a little redheaded daughter.
Her father called her his little Booster Rocket. He taught her to fly. He built nanites into her hair so she could change the colour at will. He loved her.
When he started getting 'ill' she did what she could. She flew the Maru for him so the jobs would still be done and he would still be paid. As he got worst, she looked after him and ran inteference with his creditors. Later she even took some of his jobs herself to try and keep them flying. When she realised his 'illness' was actually Flash addiction, she tried to help him quit.
As much as he loved her, Flash was always more important to him.
Rafe was her big brother. Much as he loved to tease her and get her into trouble, he protected her from anyone else who wanted to hurt her. He looked after her in strange or dangerous drifts, made sure none of the crew hurt her. He taught her how to run a con and how to avoid being conned.
When things got too difficult, he left. He took off without a word to pursue his own interests. He would return at odd intervals when he had run out of money or needed to lay low for a bit, take whatever money he could get, maybe run up some debts and then disappear again.
He had more important things to do than stick around for her.
