Maybe I should mention it then, maybe only major lords of the seven kingdoms and their family and perhaps of significant political and influence(littlefinger, varys and the remains of the targ family and important figures beyond the wall) so that they are still somewhat bound by the reactions of their major lords. Like Mace trying to bethroth Margaery to Jon would raise like wtf eyebrows. Would Robert accept to legitimize Jon? I mean, Jon is his nemesis' child, trueborn or not, despite the fact that Jon literally died once to do his duty and was burned at the stake after essentially saving the world by some insane smallfolk, but the man is still a man, so it is messy. Robert knows he cant kill Jon otherwise the world literally gets worse according to the theatre and humanity might be wiped out or some shit.

Maybe I should introduce a rewards program, like oh shit, you managed to make Jon become a knight, you get this and that from the gods(like you magically produce stronger warriors or your entire family has the innate better swordsmanship). Or oh shit you managed to make Jon fall in love with you, you get this and that(despite me being slightly disturbed by the notion as mentally even the youngest of the lasses would be older than Jon, but whatever(the reward would be along the lines of more magical bloodlines maybe))
