She's young, but older since she's spent so much time in Cryo. Technically she's 25, but thanks to being in stasis for so much of her life, she's only 18. But her appearance as a teenager doesn't make her less capable of being a Captain of a ship. Her father purchased an old M class star freighter before she was even born and was intent upon taking his family and crew "to the money" wherever it could be found. After he died, he left all of his savings and ship to his daughter who took on the task of taking her crew to the money. She's always done well for them, even though her roughneck crew don't much care for the contracts she takes from Weyland-Yutani, but the pay is always good and the jobs relatively easy. John was her caretaker her entire life, so she has a deep fondness for him and never treats him like a synth. She considers him family, and her second in command only because she owns the ship. The two are inseparable, and little does the Captain know, but John has killed to protect her before and he would do it again.
