Continuity mistake: The patient Zoe is in the ER with her boyfriend while Doug, Carol and Lydia work around her. At one point she puts her hand up to her throat, but in the next shot it's down by her hip, without enough time for the change.
Continuity mistake: Doug goes into the ER room to respond to the boy, who's saying "go away." His mother has her arm around his head and is telling the drunk with his teeth out to go away. Then the shot changes and we see the boy's head, but no mother. A quick shot change and there she is again, cradling his head.
Answer: Take care of your dad.
