When Nora/Nadia is getting her ultrasound, the doctor is moving the probe side to side on her stomach, however the image on the screen is the same and doesn't change.
At Crazy Eddie's, Nadia (as Nora) is clearly acting in front of a prerecorded video. The camera feed is not live as the 1st image doesn't move at the same time as her, which it would if it was live.
