american fellow medical students at ut, hospital staff he trains with, neighbors in a cheap and cheerful building where they can all hang out and bemoan the state of the laundry room, a nurse a few years older than him for a specific line, friends from high school who stuck by him during the awkward transfer student days, the pam to his jim back in his undergrad years when he worked at the apple store, a cousin he doesn’t get along with, anything else we can brainstorm!
