If you're rooting for the King in the North and the Mother of Dragons to form an alliance of the heart, you were probably delighted by the bedside scene in "Beyond the Wall." But the same scene contained a clue that Jon Snow will die again on Game of Thrones, something that kind of sapped the moment of its pleasure. Because it seems more than likely that Jon's decision to bend the knee to Dany will get him murdered. Again.
Remember his death at the hands of the men of the Night's Watch? It was extra painful because these were the same men who were supposed to be Team Snow. But what's been hammered home, time and again on the series, is that alliances are everything. We've seen that as recently as one episode earlier in “Eastwatch,” when Randyll and Dickon Tarly, even at the threat of being roasted to death in their armor by dragon fire, refuse to switch teams to support Daenerys in her bid to win the Iron Throne. As such, Alliser Thorne and his men's mutinous reaction to Lord Commander Jon choosing to bring Wildlings South of the Wall, though extreme, didn't exactly come out of nowhere.
After all, long before Jon rose to the position of Lord Commander, he was almost executed when he came home from acting as an undercover spy within the Free Folk's forces and the men guarding the Wall found out he had "lay with a Wildling girl." Janos Slynt demanded his life in exchange, but, thankfully, Maester Aemon interrupted before a death sentence was imposed. Trifling with the enemy? Not a trifling mistake, apparently.
For that reason, it wouldn't be unprecedented if the Northern lords reacted to Jon's latest bold decision with similar mutiny. From a rational perspective, they pledged their loyalty to Jon, not Dany. For him to offer the Mother of Dragons, someone whose entire way of life is alien to them, the use of all of his Northern lords' armies without consulting these same forces first is downright disrespectful. We have no idea where these nobles stand on issues like slavery or the use of dragons, but Dany's philosophy is wildly different to practically every other current ruler on the show, so it would probably constitute a radical change for these leaders.
But the above is the best case scenario, if these lords were calmly logical. As we know from Sansa's anxiety about them discovering the letter in which she seems to betray her family, these same nobles are volatile and won't respond well to a sudden change of plan. And they're unlikely to be happy about the idea of a foreign female leader. In Season 2, we got to see a nastier side of the Northern lords when Robb Stark fell in love with Talisa, a healer from the Free City of Volantis, who Lord Karstark calls a "foreign b*tch" and whom the men seemed contemptuous of.
But their distaste didn't seem to just be about xenophobia; it also seemed to be about the idea of a leader prioritizing their personal life over their political life. When Karstark complains to Robb that "I think you lost this war the day you married [Talisa]" after their military luck begins to run out, he's not wrong. They needed the Frey Stark alliance to keep the supply lines open.
There are parallels between Jon and the eldest Stark son's situation. Robb opts to follow his heart over his head, breaking his word (he was pledged to marry one of the Frey girls). Jon bending the knee suggests, like Robb, that he's choosing emotion over politics and risking losing his men's respect along the way. And we all know how well that usually works out.
It would be nice to be wrong. The North would be a far sadder, less photogenic place without old puppy eyes around. But given the show's fondness for bumping off those who don't play the game, his submission to Dany could mean the first step in his demise.
