Carla: Why was I told to drop everything and look after some new patient coming in?
Dr. Kelso: Mr. Sommer is the cousin of one of the trustees. Not important enough to warrant any face time with me, but connected enough that if one of these ding-dongs kills him, it'll be my ass.
J.D.: Carla, can you cover my patients?
Dr. Kelso: She's watching someone for me.
J.D.: I'll find somebody.
Carla: Because I'm just a nurse, I can't look after everybody?
Dr. Kelso: Precisely.
