Continuity mistake: When George askes Richard Webber if he could help examine Ellis Grey, the extras in the background walk down twice and suddenly appear and vanish. (00:18:10)
Continuity mistake: When everyone rushes Christina out of the OR after she collapses, Izzy suddenly loses her blue scrubs hat between shots, with no time to remove it herself. (00:23:50)
Suggested correction: She did have the time to change. And you can see in the end of the scene when Bailey is talking to her in the elevator and Izzie is outside, the mask and the hat in her hand.
Continuity mistake: We see a nurse writing down "Yang, C" on the assignments board; note the handwriting. Later, when Burke notices that Christina's name is on the board, the handwriting of "Yang, C" is completely different and other minor writing differences are noticeable too. (00:27:55 - 00:33:45)
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)
Continuity mistake: When Meredith tries to get into the OR to see Cristina, Bailey walks over to the door to stop her, and they talk. But in the final shot of Christina, you can see Bailey's hands on her head, even though Bailey is at the door with Meredith. (00:30:00)
Continuity mistake: When Derek sits in the rocking chair in the room with the premature baby and then Addison starts listing their relationship options, the blanket hanging over the back of the rocking chair constantly changes position, evident by the green stripes on it. (00:31:50)
Continuity mistake: In the bar, when Bailey tells Derek to go sit by someone who cares, she lifts her glass up from the bar table, to her lips, twice between shots. (00:01:50)
Continuity mistake: When Alex walks over to the desk that Derek is sitting behind, with the couple arguing in the background, there is a box of tissues with a tissue pulled so that it is almost out. In the next shot the tissue is barely out of the box. (00:26:20)
Audio problem: When Alex is walking over to Derek, watch the couple (the man with the gunshot wound in his head and his wife) in the background. The wife is shouting at his husband but her lips are not even moving correctly. (00:26:20)
Continuity mistake: When Dr. Miranda Bailey tries to resuscitate/reanimate her patient Jeremiah, the assistant puts the anesthesia bag down next to Jeremiah's shoulder, in the next shot however, she has the bag back in her hands and lies it down once more.
Visible crew/equipment: When Burke steps onto the elevator Miranda declines his offer to scrub in on the GSW, and just as Miranda admits to having a "date" that evening, a T-mark can be seen on the floor in front of Burke. (00:10:40)
Continuity mistake: When Meredith, Christina and Izzy are standing by the hospital hall balcony talking, the nurse, doctor and patient extras walking and passing in the background are inconsistent from shot to shot. In addition, the position of the three ladies arms / hands on the banister keeps changing during this scene. (00:12:35)
Continuity mistake: When Alex and George are trying to get out of the elevator that they are stuck in, watch the monitor screen attached to the gunshot victim. The lines on the monitor keep instantly changing appearance (from straight, to jagged, and then back, etc.), especially the middle blue line. (00:13:05)
Continuity mistake: When Alex and George are stuck in the elevator with the doors slightly open, with the gunshot wound victim, there is blue paper lining the slight opening in the elevator doors. However this paper disappears in some shots, the reappears again. (00:18:40)
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: You see Karev in the elevator with O'Malley putting on OR scrubs, in the next scene Karev isn't wearing his but a few shots later he is. Karev is wearing gloves, yet we don't see him putting them on.
Something to Talk About - S2-E7
Continuity mistake: When Nurse Debbie gives Christina all the patient files, the 'explosive diarrhoea' file that she puts at the very top of the pile disappears in the next shot and then reappears in the next shot, but turned the other way round. (00:14:40)
Something to Talk About - S2-E7
Continuity mistake: When everyone is sitting outside at the cafeteria eating lunch, in one shot Christina removes the red lid of her smoothie bottle but in the next shot it is suddenly back on. Then it keeps changing from either being on or off. (00:16:45)
Something to Talk About - S2-E7
Continuity mistake: When Christina tries to talk to Burke about their relationship, he ignores her and she walks over to the banister and leans her head on her left hand. But in the next shot her whole left arm is down on the banister rail. (00:36:35)
Continuity mistake: When Meredith puts the Hello Kitty plaster on her forehead in her car, she puts it on upside-down. When she reaches the elevator it is now on the right way up (it is unlikely she would have removed it just to place it back on the right way up.) In addition when she is in the elevator, from shot to shot the position of her fringe (and how much of it covers the plaster) keeps changing. (00:01:50 - 00:02:55)
