Corrected entry: When Dr Shepphard walks into the OR to start the brain surgery on Izzy, after already scrubbing, he touches his forehead and surgical cap. He would not have done this as he would then contaminate himself, forcing him to re-scrub.
Grey's Anatomy (2005)
1 corrected entry in season 5
Continuity mistake: When attaching the arms during surgery, they show the same arm with the tattoo "Nicole" pink up twice instead of showing both arms.
Katie Bryce: My head is full.
Dr. Meredith Grey: It's called thinking. Go with it.
Correction: True but this is not a mistake of the show. Human flaws and lapses in judgement (such as a surgeon absentmindedly touching their forehead) are not movie/show mistakes. This probably happens in real life more than anyone could know, and much worse things happen in an OR as well.
