Continuity mistake: A policeman is in the ER talking about the little boy who was shot. He gives Carol a schoolbook with the boy's name in it. She looks at it and asks, "What about Wilson's family?" and then closes it - then as the cop answers, "Workin' on it", we see her closing it again.
Continuity mistake: A detective goes into Wilson's room to talk to him, and Carol joins them, sitting near the end of the bed by Wilson's feet. A couple of shots later, as the detective talks to him, Carol is suddenly sitting by his knees, even though she never changes positions.
