Diana went first to the old man and paid him. Then she rushed to the security office of the school. She had to figure out what had happened.
Diana walked into the security office and told them her story.
Antonette stood beside Diana as she explained to them that their dormitory might have been broken into by a thief.
Antonette was relieved, at least Diana didn't suspect her and their roommates. If Diana knew they had ruined her dress and shoes, Diana wouldn't be her friend anymore. Then the roommates might tell Diana what Antonette had said about her! There would be no way to meet with Brian and Kyle without Diana as her excuse.
