Mia wanted to return home as soon as possible for three reasons. One: She was hoping Leo would give her a call but if he didn't, she was going to give him a call even though international charges were terribly high. Two: She wanted to leave the school premises as soon as possible because a lot of students kept flocking around her, asking her if she knew about Jeremy and Kelvin and wanted her to give them juicy gossips. Three: She wanted to directly hear from Jeremy about all of this. She hadn't seen it coming at all. Jeremy was hardworking, humble and respectful, he was nothing like Kelvin. How come they were brothers? It was one shocking news.
When Jeremy returned to class, everywhere became quiet. As much as people wanted to ask him questions, they couldn't bring themselves to do so, especially after watching how he beat the hell out of Kelvin earlier.
