She is supposed to be Percival's love interest in the stories so I don't think it's really possible. I think he means that she simply has no romantic feelings for anyone right now unlike Elizabeth/Diane/Merlin who loved someone from the start. And now we have Isolde who is in the same basket as Elizabeth/Diane/Merlin.
Honestly I don't find that Nasiens looks androgynous.
Well, there goes my hope.
He isn't on the level of Gowther, but I do feel like he is a bit androgynous. If Nakaba tossed some of Gowther lip gloss his way, it'd sell it way more.
That "X is the kid of Y and Z so he/she has to be overpowered" idea has to stop. It is pretty clear the the KoA are meant to be special. Unless one of King and Diane's kid is the fourth one there is no way they is going to be able to rival one of these four.
I don't see how treating Tristan like this would contradict anything in this context because Tristan is the prince of Liones and she is part of his platoon.
I think King and Diane's children are going to be ridiculously overpowered in their own right, especially given their parents. I don't see anything wrong with that. And I do believe they will be comparable to the 4 Knights when it comes to general ability and such. But only up to a certain point. Obviously, they will eventually lose out due to not being one of the titular knights, especially when we get more information on why they are special and why they were given the Horseman titles they were, but it shouldn't be a problem if they are all similarly strong at this point in time.
As for the Tristan thing, it's not a contradiction, but it does not seem right considering the fact that the two are both royalty and, potentially, childhood friends. If she was their child, her being that level of subservient to someone who should be her "political peer" so to speak just doesn't seem right.
