Other mistake: When Bella meets Edward's family, Esme's (Edward's mother) upper forehead (near her hairline) has no makeup, but the bottom portion does. You can see the difference between her pale vampire makeup and her natural skin (which is also shiny).
Other mistake: Bella's nasal canula in the hospital scene were all over her face in almost every shot and they were not connected to anything. (01:38:45)
Other mistake: When Bella is in the ER, the x-ray behind Dr. Cullen is upside down.
Chosen answer: Earlier, when the girls were shopping for prom dresses in Port Angeles, Jessica commented that the low-cut dress she was trying on made her boobs "look good." She is wearing that same dress at the prom, and Bella is gesturing and then giving a "thumbs up" that Jessica's cleavage does look good. Jessica mouths back, "I know."
