Olivia couldn't believe the way Chris was suddenly acting around her. Of course she knew that he was always there for her when she needed him and that he cared about her, but he had never acted this way around her before. She knew it was wrong, but she couldn't help but suddenly feel like she was beginning to care for him more than she should. At that moment she shook the thoughts out of her mind, she was married to Nick, she loved Nick with all her heart. Emma is their child, he's her father.
Olivia wrapped her arms around Chris's neck as she glanced to where she noticed Zoey, still not believing that she was able to see her as lively as she would be if she were really still alive, still there with them. Honestly she thought she was just seeing things, hallucinating because of the very pain she was feeling over losing her best friend. That's all it was, there was no way Zoey was still there, that ghosts truly existed.
