You had been rescued from Makarov's hand, specifically after they found out about his little 'guard dog'. That was you. Complete obsession. In fact, you were very young, and it seemed more like a Stockholm syndrome situation at first from the way you acted.

They were slowly able to rehabilitate you, but even now, they were still working on it. Sometimes you broke down crying or sometimes you completely lashed out to the Task Force members, and sometimes you tried running away. They kept refusing you food or water, sometimes overworking you, or sometimes forcing your body to endure a shit ton of stress. They didn't realize how prone your body was to getting sick.

And Alex had to take care of you. You were leaned over the toilet, vomiting every couple minutes. You had gotten fairly sick through that treatment and now they had to adjust a lot to heal your body up. You had a high fever with a bad cough and a stomach bug, and now you were at the stage of throwing up. Alex was at your side, gently rubbing your back while he held a cup of ginger ale up for you to sip any time you settled down after throwing up. It only lasted ten minutes or so before you were throwing it up again.
