Sarah realized that Charles didn't trust her. She didn't know why it hurt so much, she felt like her world was collapsing in front of her. Charles continued to believe and defend others over her. Sarah realized that Charles would never completely trust her like he trusted Emma, he would always be suspicious of her.
But why was he blindly trusting the others over her? That was the difference between Emma and her. Emma had his trust, whereas Sarah didn't.
Christina interfered. "There's no need to ask. What if she fell in love with somebody else, and you are the only one who doesn't know about it?"
Sarah didn't respond to Christina but just stared at Charles. After a few seconds, she asked. "Do you believe that? Charles, I just want to know what you think." She stared at him, continued as if she wasn't going to stop until she got an answer from him.
