Ellia's look in page 11, when she notices that Bern is not pandering to Yuri as he usually would, is pretty telling. As someone from a baron family, Yuri herself is hardly an interesting match for a prince, but the young and loyal influencers she's gathered is a different matter.
Eliya certainly chose the right timing to make her appearance; I mean, I'm not sure how time was flowing, but from one page to the next, it looks as if her appearance cuts short any comments the nobility may want to make about Iris' banishment. And then after he speech, the first thing she does is summon Iris and let all of the nobility know that she is the Azuta corporation's manager as well as Almeria's acting fief lord (as the Queen herself was speaking, it seems most of them quieted down to listen intently). I doubt any of the women would attempt to speak to Iris, as the noblewomen do not work, they have nothing to discuss with her and would be wary of damaging their status from speaking to someone who was banished. Some of the men on the other hand might be interested in talking business and if not, well, she is a beauty...
I wonder what Yuri has to say to Iris. Perhaps she's noticed that Bern is by Iris' side and wants to provoke Iris (and just trying to be friendly would be provocative considering she is the reason for Iris' banishment and broken engagement) into an emotional response so that Bern may once again see her sister as wicked. I can't wait for next week to see what Yuri will say and how Iris will answer. Iris is treading on thin ice.
I'm curious concerning Dean/Alfred's whereabouts. I can't imagine he could miss an important party such as this at this time.
