Faye did not accept that Denis was being criticized in front of her. This made her angry because she knew how he had been acting all this time.
Denis is not a perfect man, but he tries to do his best. And so far, no one has been suspicious of committing a crime.
Faye believed Denis, from his actions, and all this time he was accompanying her at her lowest point, "I'm sorry if I sound rude. But can you stop saying things that haven't happened yet? Or rather something that won't happen? Please respect me as his wife."
Charles understood what Faye was saying, he was not offended by what she said because for him it was normal for a wife to want to protect her husband. He was flattered to see the changes in her firsthand. He laughed unconsciously at the thought.
