The two of them are secretly watching this battle together with a few servants. They were in a VIP room connected that can view the central arena from a high vantage point and they initially thought that this duel was just a way for Vincent to gain sympathy.
They were sure that Vincent's combat ability has greatly decreased after being blind and there was no chance for him to win at all.
Nevertheless, since he accepted the duel, he must've planned to use this as a stage to gain sympathy or to uphold the promise made by their parents to marry her. That's right, they thought that he would use the sympathy of the crowd to gain some supporters and continue with the engagement!
This is after they heard a report that Turhan visited Vincent's cabin and the Black Tower's personnel within the Floating Ship had immediately advertised the duel to get everyone to watch.
