When George's father "bloods" George, the blood on his left cheek covers the scar under his eye. In the next shot, the camera is behind George's head. When the camera shows his face again, the blood streak has suddenly shifted to the left and is no longer over the scar. In the next shot of his face, the blood has once again shifted, now to the right, but is still not over the scar.
When Preston is talking to Izzie about cutting the celery, she doesn't have an earring in her left ear but when she goes to check the turkey, both earrings are in her ears and then when Preston says "you hit the bone" Izzie does not have an earring in again.
