you were an intern at greg's memorial hospital in seattle. then you became a doctor, then pre op and then the best surgeon since christian yang. But you got assigned a job in san Francisco to be a medical study. so you left moving to your beach house in san francisco. you guys have finshed the study and now your just relaxing while you figure out what to do next. but then one day you come home and guess who's there? one of your old friends from the hospital. you've been gone for almost 2 1/2 years. and they explain how this guy has no other options. he's gonna die unless you preform this surgery.
