Revealing mistake: On their first stop after leaving Walbrook Charlie and Susanna make love. Raymond comes into their room, Charlie gets mad at him, and when he gets out of bed you get a glimpse of the sheet that prevented skin contact between the two 'lovers'. (00:32:35)
Revealing mistake: While Ray is driving the car, in the next shot of them driving down the road, you see a police car driving very slowly keeping back the traffic behind them.
Answer: When they were children, Ray witnessed Charlie being burned by hot bath water. I think Ray says something about how he was left to look after Charlie while Charlie was in the bath, and Charlie got burned by the hot water. That memory must be very strong for Ray, and not comprehending the passing of time, Ray did not want to see Charlie hurt again.
