James is a nurse at Grey Sloan Memorial Hospital.
When the computers at Grey Sloan were hacked, the doctors were left unable to access patient medical records. Jo spent time running around the hospital, tracking down which nurse had tended to Frankie Baner, so they'd know what kind of stroke he was having so they could treat him properly. She asked James and learned that Karen had been on shift at that time, but Karen said she was tied up, so she asked Taylor to take care of Frankie. Jo found Taylor just as he was leaving the hospital and he told her that he hadn't given Frankie Vitamin K, meaning giving him heparin would probably kill him. ("Out of Nowhere")
