Elliot: Dr. Cox! Um, Mr. Tillman is my patient, too, you know.
Dr. Cox: He is?
Elliot: Yeah, I was in the room with you this morning, remember?
Dr. Cox: Uhhh, no.
Elliot: Well, I was. Anyway, um, I-if you want, I could talk to his wife, because I... just really enjoy that kind of stuff.
Dr. Cox: Wait a minute: Are you actually saying you enjoy telling people their spouses are going to die?
Elliot: ...Yep! I mean, I know that-that sounds a little bit weird, but I-I-I-I just really like being there for people; it's... kind of why I became a doctor in the first place.
Dr. Cox: Well, it's nice to know where the magic began
Elliot: Charlie, I'm gonna tell you the same thing I told you yesterday when you popped out of that haz-mat bin: I work alone, and you have somebody's else's blood on your neck. Take a shower, man.
