My headcanon for Viita.

She signed on for the Turian military to train as a field medic straight out of school, she was assigned to a small group of soldiers she ate, slept and bathed with. They became super close, a second family.

However in active duty Viita suffered panic attacks, extreme anxiety and froze on the field, costing the life of a squad member in desperate need of medical aid.

She was discharged from the military after being deemed unfit for active duty and left to pursue a medical career on the Citadel. You don't forget your mistakes and sometimes they keep you up all night. Maybe all that paperwork is good for something after all.

(I was gonna put tears? But like....can Turians cry?)
