MC is an assassin who was raised with and by his sister after the death of their parents. They were adopted by an uncle, who did his best though he was overwhelmed by the task so the two kids raised each other.
MC is highly successful and unrepentant assassin who is devoted to his sister. She and her family are the closest thing to normal that he has ever experienced and his love for his family is such that there is nothing he will not do for them. He is the ultimate professional and never acts out of anger or passion.
The sister, Diana,is fiercely protective of her little brother in part out of habit, but mostly because she knows him well. She is the voice of normalcy in Alexander’s life. She understands him in ways no one else can and is also the only character who could truly change him as he would choose her over his profession if push came to shove.
The two siblings have a strong bond though they must find time to be together unobserved since his departure from the CIA. He wants her in his life and she wants him in hers, but both understand that she is placed in peril as she is his vulnerability. The threat, if any, will never come from any of his colleagues as he is too highly respected for that to occur - but his former employers might force things and have unforeseen consequences.
I think she should either die or be gravely wounded because of the dangerous nature of her brother’s profession and their determination that they can be the exception to the rule. Their stepfather uncle believes that Alex staying in Diana’s life places her in danger. Alex is highly skilled, but so are his opponents so things will go wrong for him on occasion and either her death or incapacitation would certainly force him to choose and assess his life - possibly without her wisdom. If she dies, under the current paradigm, he would have to choose his path. His main options are to wreak revenge which is not in his character or opt to retire and honour her memory or - if she is paralyzed - go home to take care of her.
If she is neither injured nor killed he continues down the road he has travelled for the past sixteen years. He goes about his business as a ‘liquidator of corporate assets’ and has Thanksgiving and Christmas with his sister and her normal life counterpoints his. He is the assassin at the table.
My main reservation is that I think it is intriguing to have this dichotomy and her normal life offers him the hope of the same if he ever chooses to retire.
I like her character but am not sure if she should essentially continue to ground her brother or if he should be forced to find his own gyroscope.
