Looks good! Though the only thing I'd like to say is Nadalena shouldn't be seen as having a 'short fuse' because she is very good at hiding her extreme apprehension for people and social events! She can be dismissive and a bit snipey at times (similar to a Olenna Tyrell, I suppose) but she does not have emotional control issues. I apologize if that what is seem I conveyed with her character!

Beyond that, good to get some interaction (that I didn't miss) here. Curious to see where we go from here.

Oh no, Fitzgerald. Welp, I guess either a red slip or a yellow slip is coming. The problem is I do not know which!

Fair enough! Anyway, her character is loosely based on one of my older ones from another RP named Rhelissa. Here's what I wrote for that character's personality if it's useful--

“This girl is as cold as the north wind.”
—Ser Jraoth

Many words have been said about Princess Rhelissa as a person and interpretations vary from person to person with some finding her alluring, pompous, crass, honest, quiet, and harrowing. Though the actual girl on the inside is much more complicated then such beliefs of her character suggest.

At the center of Rhelissa is a girl who refuses to trust others and lives by a philosophy that to protect herself from tyrannical actions and intent is to become tyrannical in turn. In many ways this falls into her safeguard and her shield to guard her emotions, insecurities, and fears from others. After all, a princess doesn’t allow others to concern themselves with her misgivings especially when she needs to look strong as a future ruler of her kingdom. This does sadly translate into a young woman who acts detached from others emotions which does strengthen the perspective that she is a pompous and insensitive individual. Though, if you asked Rhelissa it is likely that she prefers to be seen as such instead of weak and easily manipulated as it is what she sees as the alternative to the image she has defined. If someone were to gain her trust it would take much weathering of her perspective and even then Rhelissa would likely not admit it or even acknowledge that it has happened because if she were to trust she would be betraying what she has seen firsthand — she would never break her vow to never forget what she knows people are capable of and how insidious they truly are.

Beyond that, Rhelissa’s traits extend to her introspective and quiet nature; though that does not that mean she is particularly shy or unsociable. When she has one of her “moods” she can be excessively abrasive, crass, and blunt — especially if out of earshot from those who have right to scold her for it. She knows her station and will consistently remind people of the cold pragmatic truth of a situation in what she views as a sincere truth as she believes coddling their delusional fantasies of the world will only result in their own misfortune. But then again if it is misfortune that individual wants disguised as ideals, she’ll gladly let them have it but will keep a strong superior sensibility in her mind when she is proven right.

However, her crass and blunt honesty does not mean Rhelissa isn’t sympathetic towards others. She wants to ensure harm does not befall others like she has seen despite themselves possibly being potential enemies or rivals, but given her trust issues she will never open up to them unless given ample reason to due to her doubts of what such heartfelt weakness could bring. Princesses do not show weakness, give opportunity to be manipulated, or make true friendship out of naïve ideals — that would be the doom of them. Such sympathy goes towards other ways, although subtle and sometimes insular. She always treats her servants with at least enough respect that they deserve as fellow humans, but if she has wronged them would not be in mind to apologize. Perhaps this is an obsession on “appearing weak”, but despite this she is not dark-hearted in reality and when she overhears the words people say about her she does not bear them without sorrow. She doesn’t want to be thought ill of, but she cannot let people know how it affects her. Not ever.

Oh I have to tell you that there's one thing wrong in your post that Nadalena wouldn't mistake that easily. Seyrun is actually a princess as well. She's the first one in Nordland's succession line, just waiting to come of age before taking the crown from Nordland's actual regent (her uncle), after her parents passed away a few years ago.

I was under the impression that the heirs of grand dukes are not regarded as princesses. Just read up on it. Typical inconsistencies in my knowledge of medieval history. It’ll be amended in an edit.

PS:

She might. Eventually.
