After Aria left the apartment, Ivy got ready too. Although she did not have to go to work anymore, she had to go meet Max and the others in his house. They had to discuss their future and also about what Max had in mind. He had told them that he had a plan and wanted to discuss it with them.
Ivy was ready to leave. But when she stepped out of her apartment, she remembered Tim following her everywhere she had gone yesterday. She did know if Joshua had realized them being followed, but with his acute senses, she was sure he must have noticed something suspicious. If Tim had planned to keep an eye on her, then there might be a possibility of him waiting outside her apartment building to follow her again.
