(As We Know It) (Part II) - S2-E18
Character mistake: Meredith states that she cannot remember the last time her and Derek kissed. Derek says that the last time was when they were still dating, but it was actually at the end of season two episode three, after Addison arrived in Seattle and Derek and Meredith had stopped seeing each other. (00:40:00)
Suggested correction: She is referring to the last time they kissed without any issues. The last time they were good.

Continuity mistake: Arizona is wearing fitting black slacks and black heels and has two legs (not a prosthetic on the left). (00:37:45)
Factual error: Derek performs CPR on Meredith in the back of the ambulance, but he does so incorrectly. He gives one breath and five compressions instead of two and thirty. Also, drowning victims need oxygen, and Derek should have used a BVM to ventilate Meredith, not mouth to mouth. Any doctor would have known how to provide proper treatment.
Factual error: Izzie tells her patient, Cheyenne and her mother, Mrs. Ward that they live in the same town she grew up in - Chehalis, Washington, yet mispronounces it. She says CH-halis (like CHurch) when it is SH-halis like Chinook Salmon.

Continuity mistake: When Derek talks with Mr. Chue in the rain under their umbrellas, in one shot Mr. Chue takes a big puff on his cigar. But in the next shot his face is relaxed and it is clear he didn't inhale; and then he takes the same puff again instantly anyway. (00:19:20)
Continuity mistake: As Meredith tries to get in to see Christina, but Bailey walks over to stop her, Meredith is putting on a white surgical mask. In the frontal shot she ties the white straps of the mask into bows. But in the next shot from behind the straps hang loose and aren't in bows. (00:29:50)
