The longer you think about it the less sense it all makes on any level...
"Hey Jon, you killed my mother, i'm so angry, so angry, I'm going to passive-aggressively burn this here random furniture. Roaaar." What?!
He's fond of Jon, albeit ****** but can't bring himself to kill him - who knows how a Dragon thinks or it's reasoning?
"Hey Jon, you killed our queen, we normally just finish off hostages on the spot, on the street, but we are going to put you under arrest, so our other prisoner and his friends can decide your fate and then we are going to forget about you." What?!
We have no idea how that played out.
"Hey Jon, you kill Khalisi, we pillage, we kill, we angry, Dorthraki memory short, two weeks, we pass you on the street, we remember nothing, bye". What?!
"Hey Jon, you killed that crazy usurper that wanted to burn the whole world, you are also our leader, the only right heir to the throne. We had a chat and we want to strip you from your honours and titles and send you to Siberia for the rest of your life." What?!
Iron Islands, Dorne and Unsullised wouldn't have settled for anything less.
"Hey Jon, this is your family, remember that chat we had about your lineage to the throne? Well, thanks for being our King of The North, Sansa is now the Queen, Bran is The King, goodluck behind the wall honey, wear a hoodie and stay warm" What?!
See above, civil war. He never wanted the Throne before. What about Jons character do you think would mean he'd accept it now even if it meant probably civil war and after he killed the woman he loved? Now THAT would be out of character.
"Hey Jon, this is Lord of The Light, I resurrected you for purpose, you may recall. The purpose was so you can continue to know nothing and be completely useless. Lol." What?!
He saved the world from fire, the last time the promised one saved it from ice. Both had to kill their loves to do it. Pay some attention.
Who writes these things?
We had so many crazy fan fiction scenarios in comparison, you know - Bran time travelling and sending Mad King into madness with whispers, Bran time travelling and warging into someone turned by Night King and becoming trapped in a loop of trying to kill his future self as white walker general so he can't travel back and give Night King knowledge of the future, etc, etc - and all those scenarios would work our better than what we got from these... I don't even know how to describe them - it's like primary school level of story telling there...
