Continuity mistake: Walt shows up to the first crime scene after visiting his daughter. He and Vic begin to discuss the girl. In the first shot of the girl, she is facing the camera and has her eyes closed. The very next shot of her, her head has moved and her eyes are open.
Other mistake: In the opening shot of the dead girl, there's a $1 bill next to her face. However, the picture on the $1 is not George Washington.
Continuity mistake: Vic and Walt are driving and Vic is talking about how she could be a stripper. This scene must have been filmed at two different times of the day as the sun is on Walt's side for his scene, and Vic's side for hers. Look at the shadows and sun glare in the shots.
Answer: Something he made up.
