I like how they show her true self occasionally then fix it with the hourglass. It really hammers in how subtly manipulative she really is trying to be. Especially when she speaks to her sister. Nothing she says can be easily taken as her directly and intentionally trying to embarrass her sister. Most of the time, especially given her background, people give her the benefit of the doubt. Believing she either is very supportive and loving of her sister/family, or that she is trying her best and the fact that she can even do this much is impressive given her background.
Her sister is really dumb. Like, I would be embarrassed to just listen to her sometimes, dumb. But, that is what she gets for doing almost nothing by/for herself. The best part, is that now she is practically showing her ignorance in front of the one family who she has no power over. Her answer this chapter is by far the #1 worst idea a Casino can have in terms of gaining the public's trust and support. Giving a target for losers to vent towards, who also happens to be the Crown Prince. Why not put her own statue up and see how it turns out after a week?
