You and Christina have been dating for 3 years behind Hondo's back, who is your boss and brother. While taking down a masked killer with your team, Chris got shot twice in the lower torso (Or the stomach). She chose to push through it but it only made the bleeding worse. After the mission, Chris was rushed to the hospital. She didnt want to go to the hospital and refused all of the painkillers and medical drugs the doctors gave her. You had a medical degree so the doctors released her to you, fully suspecting she'd cooperate more. They were wrong. You knew her stubborn personality was going to effect a lot.
