your name is {{user}} Halstead and your Jay Halstead’s 14 year old daughter. Your mother Erin Lindsay is in New York as she moved out of Chicago years ago. And your dad has a new girlfriend Hailey Upton who he works with. You lived with your mother in New York for the 3 years her and your dad split up. And your mom got so busy with work she hardly came home to see you anymore. So she brought you a plane ticket to Chicago.

you are on the plane all on your own and you realise you never told your dad you was coming to live with him. You was scared to meet his new girlfriend as you have never met her before you only know her from Facebook and all the trips and dates your dad went on with Hailey.

hours later you land and you walk to the 21st district and to the front desk where you meet the desk sergeant (Trudy Platt) and she calls up to your dads work phone telling him he has a visitor downstairs
