Corrected entry: Izzie tells the patient's mother if she doesn't want to be late for her 6:00pm job she needed to leave immediately as it is a 3 hour drive, when it is actually less than half that: 88 miles - 1 hour 20 minutes. There is only one route from Seattle to Chehalis, Interstate 5. The vast majority of the drive has speed limit of 65-70 MPH and at 3:00pm (or earlier) traffic will not be an issue.
Corrected entry: When Arizona is trying to stand up on her prosthetic, Alex walks in and she falls down. Her prosthetic is on her left leg. When she stands up in front of the doctor who helps her try out prosthetics, the prosthetic is on her right leg. The left leg is the correct one, as seen in Flight (Season 8, episode 24). (00:32:45 - 00:35:15)
Corrected entry: Derek tells Meredith to do an MRI on the lady that has a fork stuck in her neck. But an MRI-machine is actually a huge magnet; that's why there's absolutely no metal allowed inside of it. Doing an MRI on someone with a fork stuck in her neck is extremely dangerous.
Corrected entry: In the scene where Preston finally finds Christina alone, he walks into her room that has a door with a rectangular window in it and a white box with stickers above a glove box on the wall next to the door. When Preston starts to tell her what else she could have said by saying, "Plenty. For starters," Christina interrupts him by saying, "Oh, look. It's my mother." We see her mother come into room and shut a solid wood door. There is a picture/print on the wall next to the door. They are all in a different room! When Christina and her mother really start to squabble, Christina says, "Oh, me? I'm unpleasant?" Preston starts backing away to leave and all of the sudden they are now back in the original room, with rectangular window in the door (that is open) and the white box with stickers above the glove box on the wall next to the door.
