Shared Past?

Jordan sitting in the passenger seat in the front, wondered why Arthur asked the car to stop in the middle of the road.

Could there be any trouble in the back? Did Sophia try something on Arthur and made him mad? Is Arthur trying to kill her?

As he was wondering, he heard the bang in the glass panel behind him and felt his blood flowing backwards. It was a sharp bang as if a skull was bashed on it and even the driver was startled.

Jordan was the first to step out of the car to open the door in the back and the moment he opened, he coughed slightly and waved the cigar smoke coming from the inside and his eyes watered as the smoke got in his eyes.

Was he trying to bake himself with this much smoke? Can't he hold his urge to smoke until he dropped the Lady at her home?
