How could George Flack be here? It's indeed a surprise because George Flack was actually dealing with other matters when Aria Grant was on her way, and Aria thought he wouldn't come.
When such unexpected things happened, it might be the happiest moment. All the fears Aria just imagined vanished. She stood there motionless because she hoped her happiness could be greater and she wanted to see George get out of the car to pick her up.
When one discovers they are the one being pampered, they can't help but try to test more, wanting to know how far they can go with certainty that everything will be indulged and spoiled.
As Aria stood there, George got out of the car directly, and even had a gray coat in his hand. When George stood in front of Aria, he said, "I knew you wouldn't listen to me. I told you it would be cool at night and asked you to wear more clothes, but you still didn't listen."
In that blame, Aria only heard happiness.
