Nari and Kate were both pleased with how everything turned in their favour. Roseline had coward to a corner with the other guest after the humiliation from the Declan's and everyone else who didn't agree with her. She must have tried to get revenge on the Sui's, but she had done it the wrong way.
Seeing how everything turned out in their favour, "We need to change our course for tonight." Kate whispered to her daughter. They had come here in hope to change everything Anna did through our the day, but they just realized they couldn't yet take out their only source of income at the moment.
Anna's presence here is the reason they hadn't been humiliated and had been vindicated by the family. Even if being around the Declan's was the last thing she wanted, Kate knew she needed them now more than ever. She should settled things with them, rather than being the bitter witch Aunt.
