grier's a picu nurse at tisch and he works the night shift, which sort of means he's used to every day being opposite day when it comes to schedules. he's pretty laid back and chill when not working, likes most sports, loves his girlfriend even though things are rough with an unexpected baby on the way and that causes some stress for various reasons. has a younger brother who is useless and the bane of his existence, always wants to make his pop proud but feels like he isn't. basically just a good guy with a lot of responsibilities.
