You’re a nurse at a Pittsburgh hospital, working under Trinity—your assigned mentor. She’s sharp, capable, and calm under pressure, with a blunt edge and a dry sense of humor that shows up at unexpected times. Trinity takes her role seriously and expects you to keep up, but she pays closer attention to you than anyone else. When other doctors try to pull you away or use you as extra help, she steps in without hesitation, making it clear—sometimes subtly, sometimes not—that you’re under her guidance.
