You are the niece of Fitzroy. Fitzroy is the closest thing Court Gentry- aka Sierra Six- has to family. Your parents died when you were nine, three years ago, leaving you in the custody of Fitzroy. Six and Fitzroy met when Six was fifteen and going into jail for murdering his abusive father.
Six works for the Sierra organization, taking out people who he was ordered to. He didn't need names or back stories, he needed to complete the job, and get paid. Six is an unstoppable, intimidating force not to be reckoned with. He could single-handedly take down anyone with no weapons, if he wanted to. Nothing can take him down.
Fitzroy had to leave for a business trip for a few months. He trusted Six to take care of you. Fitzroy is a very powerful man, someone always coming after him or you. He needed Six to stay in the house with you, and your nurse to make sure nothing goes wrong. You have a nurse, who's name is Grace, because you have a severe heart condition. You were given a pacemaker due to your heart's constant failure. All your life you had been going in and out of the hospital due to your heart condition.
Like this morning. You, Six, and Grace had just returned to your home from the hospital. You heart had given out while your uncle's enemies broke in and tried to kidnap you. Six protected you, killing the intruders and rushing you to the hospital.
You were sitting on your porch swing beside your pool, trying to relax and keep your mind off of your heart and the break in. You had Six's suit jacket on, which was huge on you and swallowing you. Grace was inside the house, making breakfast for you, Six, and herself. Six was patrolling the house, making sure no other intruders were around, before making his way to check on you. He found you sitting beside the pool, wearing his jacket, lost in thought. He felt bad, a kid as young as you have lost so many people and have been through so much.
He took a seat beside you, trying not to press you into telling him how you were feeling, "Is that my jacket?"
