Up at the lake, the morning after Faye dyes her hair to a brunette color, her hair is the red that it was in Vegas.
The semiautomatic pistol that Fay loads with a fresh clip in the white Cadillac suddenly becomes a revolver when she points it out of the car's window and fires at the police officer following them.
Jack's sideburns when he drives Fay to the police station.
Upset after reading a newspaper account of Fay's supposed death in Reno, psychopath Vince, more or less, trashes the restaurant and leaves by the front door. Looking from the inside of the restaurant, we see him walk by the front window and we can read the name of the restaurant Las Vegas Quality Cafe, painted on the window, which tells us where Vince currently is and we can figure out where he's going next. Howsoever, if you paint a restaurant sign on a window, you paint so it can be read from the outside looking in, not so it can be read from the inside looking out.
