Yes, everyone needs to remember what happened before:
Bran is with the Northern Lords.
Bran is a Time Lord ;) who just witnessed the breach of the Wall by the Army of the Dead at Eastwatch, and he knows the NK has one of Dany's dragons.
There's a bigger issue than anyone bending the knee.
That^ remains the top of the list, at all times.
Everyone knows The Mad King killed Rickard & Brandon, not the collective Targaryen House. Just crazy Dad, who is rarely referred to by his actual name.
Most everyone who isn't Robert Baratheon knows Rhaegar and Lyanna were in love, especially everyone who was at the Tourney of Harrenhal.
Most everyone knows Rhaegar snubbed his own wife at the Tourney of Harrenhal, to publicly proclaim that love.
Looking back from where the Northern Lords are currently, they all probably realize the folly of Brandon and his boys attempting to stand up for Robert Baratheon and Lyanna's honor, in the way they did. After all, Rhaegar (the Crown prince) did take off with another man's promised property, which is a financial arrangement between houses, but they were young, and stupidly hot-headed.
Jon and Dany are on their way north.
After capturing a wight north of the wall, bringing it to King's Landing, parlaying with Queen Insanity, and forming a new alliance between Houses. They're just not how they assume. ;)
At this point, I don't know that anything else matters other than RUN FOR YOUR LIVES!!!! However...I doubt Jon will march into Winterfell, and demand everyone bend the knee to Dany. And there are so many different ways this could play out, depending on when the show/books wants to drop the Who the hell is Aegon Stark-Targaryen bomb on the populace, now or the last episode? I personally think it needs to out soon, because there's too much else happening after they kill the NK - there's still the rest of the clean up to happen with Cersei, Euron, and how they die so Jon gets the IT...and Davos, Brienne, Tormund, Arya, Sansa & Tyrion, Gendry... how do Varys and Melisandre die? etc.... So I think the NK battle has got to come sooner, rather than later, because they're about a week or less from ... humanity? right?
Sam and Bran will likely demand to speak to Jon immediately.
*Thinking of Book Sam, and what he did to force Jon to take charge with the NIght's Watch election.... why wouldn't Sam tell everyone, starting with a raven to the Citadel? That way, it would be on record, who Jon is. (Not important that the Citadel still needs to verify, it's on record, and that Septon's diary becomes super valuable.) That way, Jon couldn't demand he keep it secret..which I can see him doing, but I doubt that will happen.
It doesn't really matter - the bottomline is, Jon is the heir. Dany is not. This is not a democracy or a meritocracy. It's a monarchy. At least now, until things are stable enough to introduce democracy outside of The Bay of Dragons.
It won't matter that Jon bent the Knee to Dany - all that is about to change due to the info Sam and Bran have - even if Sam tells no one. It will out.
I think it would be brilliant if it all happens in the same scene because the comedy would be awesome: Jon begins announcing what has happened at the parlay regarding Cersei agreeing to a truce, and we're all going to fight the NK..... "and I've decided it's on our best interest to join forces with House Targaryen, and -" Bran could either let him finish, and make the room have a WTF moment, making Dany uncomfortable, forcing Jon to admit they were married... (ship's captain?) or not - either way, Bran interrupts and tells them entire room that Jon is in no position to bend the knee to Daenerys, because it's not his place, It's Dany's. Then he explains who Jon is, Sam verifies.
Dany, who is all about the Line of Succession, and who has idolized her brother her entire life, suddenly discovers his son is alive, in love with her, (the father of the child we all know she's carrying because of the metric shiteload of foreshadowing), and he's the heir to the Iron Throne that will instantly unite the army before her that's humanity's only chance for survival.....turns and bends the knee herself, because it's never been about her, it's been about making the world better, and she thought she had a great claim to do that. She actually wants to DO THE JOB, not just have the title. If the title gives her the job, then she goes for the title. If she can still do the same job without the title, she does the job.
...and THERE'S NO TIME for anything else, because some horrid man stole her dragon. Again. (In private Jon tells her, they're going to rule together...)
The Northern Lords are happy because they love Jon. Jon will sit the Iron Throne (perhaps not literally even though it apparently survives a burned out Red Keep), Dany and he will marry (although I want them to be the third secret marriage like Rhaegar & Robb), and their heir will rule after them.
As fast as the story needs to go in only six more eps - even if they're 90min each - this info needs the bandaid ripped off so everyone has the info at once, and something like that would be an easy info dump, to the widest bunch of characters as possible, at this point, where people are on the map. Maybe Jamie caught up with them?
Which makes me wonder where everyone who isn't on that one ship we saw sailing north, actually are on the map? The Unsullied, the Vale army, the Dothraki...? Ships are faster. Does Jamie bring his army? Sooooo many questions!
