Sarah thought that Mrs. Thomas would change her mind and then like her over time. And then her marriage would be happy. But now, it was impossible. Mrs. Thomas didn't like her at all, and didn't seem like she was open to ever liking Sarah one day – she just wanted to drive her away.
Although she knew that Mr. Thomas and Charles would support her and that Emma didn't mean to destroy her family, Sarah still felt uncomfortable, and even a little sad.
She went back to the ward and found her cellphone. Mr. Thomas was sleeping, so she didn't wake him up. She just glanced at him and was about to leave. Mrs. Thomas and Emma came back at this moment.
Emma was surprised, "Sister, why are you here? When did you come back? I didn't see you."
The place where they had the conversation just now was the only way to the ward. They stayed there the whole time and didn't see Sarah, so when they saw her in the ward, they were surprised.
