@Ecuadorzqueen Might be overcooking this hate-train just a bit there. We have had very limited exposure to the former royal family except for a few key members, and only the ones whom actively socialize with Rozemyne. As an adult, Nahelache didn't have any way to actively meet Rozemyne prior to the events in P5. After that, she was more involved in adult socializing outside of Rozemyne's scope of focus. Rozemyne is quite famous for being overly focused, would it really be that strange if Nahelache was working her butt off socializing in the P5V5 archduke conference without Rozemyne noticing or hearing anything?
Point is, we have very little exposure to her character. What we have seen isn't terribly flattering, but I wouldn't take that and immediately claim she is worse than Detlinde. At the very least she appears to possess more intelligence than that......christmas tree. Trying to claim that a noble is unworthy of their title because Rozemyne of all people didn't notice them before isn't a very strong claim.
Of course she could turn out to be just the worst, but lets not immediately jump to conclusions. I still remember when the forum went on a Sylvester hate-train in the middle of P5V4 prepub over the course of a single week.
