Arthur wasn't really planning to follow them but he was curious as to whom she borrowed the car from. He knew that Cayenne didn't have much money and it bothered him a little that someone took her away from him. He wouldn't let anyone take her away.
As he continued to follow them, he saw Cayenne and her mother got inside the blue BMW convertible car. His eyebrow raised as he tried to take a glimpse of the driver.
Stefan made sure that all his car windows are tinted, therefore, no matter how much Arthur wanted to see him, he couldn't see his face. After making sure that they were both settled down, Stefan turned on the engine and drove out of the hospital's parking lot.
