Nadricka knows - she admitted it to him really early on :D
When did she admit? she told him that she lost her memories but she didn't tell him him that she's not the real princess
True, she did not.
But previously at the ball (or on it's way, not sure) Nadrica say it to himself "not your are not" - admitting that he know that she isn't the real princess.
Yeah, that's why i said that he knows it and he's just pretending
Yep
Robia done exposed her ass, what the hell she gon do now...ugh....but i think Nadrika knows that she's not the real princess as well, he's just pretending
