What are Eirene's and Hypatia's opinions on Adelaide?
Probably hate him to death, but that would be too easy. It's maybe more complicated than just pure hate.
For Hypatia, it's probably mixed feelings. For one Adelaide is her greatest supporter and ally during her research on aurum secretum, when Hypatia was unaware of her brother's true intentions with her inventions and research. So, you can guess that she trusted him a lot, especially since the Campbell family is known to be really competitive, and Hypatia was never close with her older sister Eirene for that matter. I don't think we've gotten any information of them talking to each other yet. After Hypatia finds out Adelaide's true motives, you can already assume the immense betrayal and hurt from it. Because he was her supporter. He was someone she can consider as family, even though there was still a bit of distance between them. This was the first time someone in the family acknowledged her and it was all just snuffed outāan elaborate lie.
On the other hand, we have Eirene. I don't have her, so I can't base this off of extra info. However, I do know that she isn't close to her family either. She was forced to grow up early and she hated all of it, despite following the business minded approach her family were notorious for having. When word of her brother's shenanigans during the Expo came to her, I'd like to imagine that there is disgust. Not for Hypatia's behalf (that would come later), but moreso on him staining the Campbell name with him being a Sage of the Underground. Because while she doesn't usually care of the questionable things her family does, this one in particular struck a chord with her for some reason.
