I just want a universe that makes sense. Even if you think its nitpicky, Jon couldn't sway any house to his side. And Sansa/Littlefingers' Vale army won the battle. And he's a bastard. And he's a Night's Watch deserter. And he lead a suicide charge, undermining any strategy they had. Yeah, it makes the show easier to enjoy if you hand wave all that away, but it all happened. It's a part of the story. If you don't care, that's fine, but that doesn't mean it's untrue or unimportant.
...I had a longer, more well-written post in mind, but all of that actually
is unimportant, so
- People don't sign up to follow ambassadors or advisers who do the convincing for their superiors.
- Jon Snow led the army that fought the battle to take the North back from the traitorous house that sold them out to the South, when most of the other houses were too chickenshit to even show up
- That he's a bastard with the rest of the Stark men dead is probably the least important of all the unimportant stuff here
- No one gives a shit about the Night's Watch at this point, plus he was the Lord Commander, plus no one in the Night's Watch is chasing him, plus "Fuck you you left the Night's Watch to reclaim the North when none of us had the nuts to do anything about it I hate you Jon Snow" doesn't make sense
- That the battle is won and at the end of it Jon Snow is the de facto Lord of Winterfell is the only thing that matters about the battle
- Including that Littlefinger showed up and saved the day because he's still not going to be King in the North
I mean, all of this stuff should be immediately apparent
Jon Snow led the army that won the battle to retake/avenge the North while showing up every other chickenshit Northern house, and he's the last living son of Ned Stark sitting at the head of the table in Winterfell. Anything beyond that is pretty marginal.
