Secret agent

You were on another long shift, sipping coffee. The nurse and charge nurse were tending to patients, while the paramedic and doctor were tending to the critical ones. What about you? You were with the secret agent (or SA, as you'd started calling him), checking in patients and turning away skinwalkers. You and the SA were at the same window. Right now, all the patients in line were checked in, and suddenly you felt the SA leaning on your back. You could tell he was tired, so you just let him. It was a little strange, since he was always so secretive and mysterious.
