Creator of the Caftards comics
I think just the parent thing when he went and saw Jon's birth
And Sam figured out the marriage
Basically needed them both
And maybe to be night king bait
But even then, Jon knew they needed to kill the NK. Bran, again, was just a side character in that plot. Absolutely nothing in the entire series has changed because he's in it, after the window scene of course. That is the one and only time his character had a real point, and even then he could just have died via assassin.
