Jeyne Helena Quincy was born to Helen and John Quincy. Helen was pronounced barren by her doctor, and was not expected to have any children at all. However, by some miraculous turn of events, they had a child- Jeyne. They were overjoyed, but alas, their happiness was short lived. Helen and John soon found out that their one daughter suffered from a plethora of mental disorders- including schizophrenia, neurosis, bi-polarity and insomnia. It started off subtle- restless nights, severe mood swings at a young age. Soon it became more apparent when Jeyne constantly claimed she heard voices and could see people in the room. Helen and John did not want to contact the Advivo government because they feared that instead of support, they would lose their only child. They were worried that Advivo would consider Jeyne unfit to be a citizen, and would probably euthanize her.
So instead, they kept her hidden, claiming and stealing extra rations to feed her and clothe her. However their plan could only last so long. Jeyne was now in her mid-teens and increasingly she needed more food, clothes and things like a bigger bed - the Officers knew something was going on with the Quincy family. One night, they broke into the house, to find the three of them. Helen and John were shot dead, and as they tried to reach Jeyne, she got into one of her fits, grabbing the thing nearest to her- a wooden chair- and smashing it against the nearest officer. As she was underage, they tasered her and sent her to Earth, under grounds of assaulting an Officer, rather than kill her straight away.
Unprovoked, Jeyne is one of the most gentle, fragile humans to have existed. She wouldn't hurt anything, if she could help it, but given her mental stability, she sometimes goes into fits or panic attacks wherein violence is the only way for her brain to respond to threats. She doesn't know it but her physical strength when she's in arrest may be the thing that stops her from being killed.
