I mean yeah thats usually the reasoning behind that 20 year old theory is that it would Karmic justice for Tywin, I don't think George cares about such things tbh. I also don't think there are Prima Nocta laws in Westeros. Yeah i think Bran and Bloodraven will be the bad guys. Maybe even using Jon after his "death" to be a host for the Great Other. Nights king is mostly a show thing, while there was a night king in the books they are a thing of the past and the Great Other is the name most used in the books. I also think Bloodraven has Dark sister and it ends up with Arya as a replacement for the dagger she kills the "Nights King" with in the show. She will be wearing someone elses face while she does the deed, or she will die and Jon will snap out bran/bloodravens control and kill the Other. If she dies it could fulfil the dream i think she, Jon or Bran had where someone saw Arya frozen to death near the trident. Jon getting Dawn only makes sense to me if he is Ned and Ashara Daynes kid. While that theory is more fun imo then R+L=J. I read to much of the Hersey threads on the original ASOIAF forums so i will always hold out hope that Ned is Jon's real dad but i severely doubt it. Edric "Ned" Dayne having Dawn is more likely imo. Jon already has a Valyrian steel sword and i think him giving it to Jorah or offering it to him is a show only thing. He wont ever meet Jorah most likely or if he does Jon will be post resseruction and he will be more like Beric/Lady Stoneheart and less human and less likely to care about jorah being the former lord commanders, slaver son. I don't think Dany will get one of the swords nor will Aegon unless he already has it or obtains it after taking Kings Landing which i think he will do. Dany has never used a sword it would be a waste. Visenya and basically every Targaryen to carry Dark Sister has been kind of a bad ass fighter. Your Ideas here would still be a hell of a lot better then what we got in season 8 lol.
