Aria intended to throw the business card away; she didn't care about the person's identity. Even if she encountered any issue with her body in the future, she wasn't expecting help from that person. After all, she had plenty of money. Besides, she was hit earlier because she hadn't been watching the road.
However, there was no trash can nearby. Out of options, Aria just put the business card back into her purse.
Although it was very far from school to home, Aria was doubtful that the two children could find their way back. Regardless, Aria followed the most likely route they might have taken, thinking that maybe they would ask for directions along the way, or perhaps they were just ahead of her? So at this point, Aria was getting farther and farther away from the school.
