Samara did not expect to meet Chaim. She did not want to see him, so she naturally did not feel guilty. She just did not want his suspicious and disdainful expression to remind her that she had lost him again and again.
Moreover, she was holding Kadin's arm.
Kadin had protected her since she was a child. When she was in middle school, her parents were called to school because of her fighting. The first thing Kadin did was to ask her if she was injured. Then he inquired about the ins and outs of the matter. In the end, he asked her to apologize.
There was no right or wrong in her relationship with Chaim. She had insisted on marrying into the Humphrey family.
However, Chaim had never treated her as his wife and had not protected her for the past three years.
When Chaim and Samara had first divorced, if she had not stopped Kadin, Kadin would have taken people to the Humphrey family to settle the score.
