After Ivan and Harold welcomed the rest of the guests, they both went their separate ways. Harold had sent Alvin on an errand earlier, so he went in search of him while Ivan returned to bond with his new potential bride.
Earlier when they were going for breakfast, the two had something to prove, so they had acted friendly to each other. Ivan wanted to hurt Luciana and show Harold how much power he had accumulated, while Benedicta was trying to prove to Harold how much he was missing from rejecting her. At this point, she didn't care about anything. She was going to marry Ivan, and with her family's influence, she was going to make sure Ivan became king and her queen.
Now that they both had no one to prove anything to, they both walked in silence while Ivan continued to sigh, which irritated Benedicta so much.
