Goof: When Carol and Luka go through Trauma 1 to get to Trauma 2, a crew member can be seen as they walk through the door. They even roll out of frame.
Goof: When Mark is extubating Dr. Hudson, it's clearly seen that the other end of the tube is under his hand and not being removed from Hudson's mouth.
At one point Luka says "Cutty-pie" instead of "Cutie-pie," the very first of many "Lukaisms" to come.
Mark: It's not good medicine for...
David Greene: ...for one family member to look after another.
Carol: Don't they have Valentines Day in Croatia?
Luka: Oh yes we do. We even have these little hearts. (reads the Love Hearts) "Be mine"...
Carol: I don't recomend you eating that.
Luka: ..."Dear one"...
Carol: I gotta get to radiology.
Carol: That's "Cutie-pie".
Luka: (sarcastically) Oh, thank you.
Carter: Ya know, there are warmer places to be alone. There's the furnace in the basement and the incubators up in the NICU.
Abby: I'd like to see you in an incubator in the NICU.
Carter: I'm happy to try.
Abby: All those years as an OB Nurse, 98% of what you see is pure joy. It's the happiest day of most people's lives. And the tragedy is horrible... 'cause it's a life cut short. The mom... the baby...
Abby: Today was the first day I saw an old person die and I guess I'm just not used to it.
Carter: Well, you want the good news or the bad news?
Abby: Give me the bad.
Carter: You never get used to it. The good news is you never get used to it. At least I haven't. So you may have come up here to be alone -- but you're not.
Greene: (to Chen and Malucci) Do you know why I had only one child? Because I didn't want to listen to the two of them arguing in the back seat of my car.
Elizabeth: I'm sorry, Robert, I just don't think it's proper to be operating on your dog.
Robert: I'm chief of staff, is that proper enough for you? Besides, what would you have me do? Leave her to some poodle surgeon?
Elizabeth: Robert, this is a dog.
Robert: Correction, Lizzie, this is my dog.
