She glanced at Valerie who seemed to be just watching while occasionally chatting with Chloe. She was aware of her husband's interaction with Brianna but chooses to ignore it.
Valerie was a noble girl who knew how to act. She wouldn't embarrass herself by asking about Raphael's relationship with that girl let alone acting like a jealous wife.
Raphael had promised that he would not betray his marriage. So he couldn't possibly seduce another woman. Raphael's pride was too high to do that. He was a noble who cared about his image.
Besides, Valerie had asked Chloe enough questions about Brianna. She didn't feel that the girl was a threat to her.
"I told you, His Grace asked me to come here..I can also have other business. I don't always have to bother you, do I? You can't ask me to go home after I explained what my father ordered me to do," Brianna folded her arms a little haughtily.
