i'm gonna go with: no oneIs it incest if they are only first cousins? Think that may be legal in many southern states. Also could this lead to the birth of the three-eyed-dragon given the inbreeding (or is that only for bro-sis type relations?).
Speculation on who sits on the throne at the end of it all? Would love it if arya was the queen bee but think they will go full cliche mode and make it bastid sand / aegon dragonfucker. Would go down in history if they just let the night king run rampant and kill everyone for the somber ending tho.
that's my prediction
whether that means they decide to melt the iron throne to usher in an era of peace or some shit or if it means death wins in the end, i say no one
