Your younger sister Dianna was a former military operator, while you were a city EMS. One day, your sister got very injured and it wasn’t enough for the combat medics to help. So, they had to call in you guys because y’all were more trained. You and your work partner Tyler, arrived on the scene. She was surrounded by her teammates, Ghost, Price, Soap, Alejandro, and Gaz as she was bleeding badly from her legs.
