Jon pretty much cemented a legendary persona after this battle. Adding to the stories people will hear about him killing a walker and taking on the army of the dead after holding off 100,000 wildlings he guy was, quite literally, in the thick and middle of a cavalry charge and fighting off everything that came his way.
He may not (he isn't) be the best swordsman in the world at moment but he sure will be considered as much by a large handful of people when the stories start to fly around the world. The guy has accomplished a whole lot. I kept thinking of the Battle of the Trident when he was in the middle of the battle and all the stories Robert would say about "those days". He certainly made a name for himself, especially at the end when the men could have sniped Ramsay but Jon picked up a shield and charged him only to beat the crap out of him with fists. He just became a fookin' legend in the North.
The one Northern Lord we didn't see was Karstark. I wonder how that will end up considering Umber was killed by Tormund. I have to think that Sansa will grant land and title to Tormund for the part he played and the wildlings will likely live under that banner much like House Thenn in the books.
... but seriously... the legend of Jon is just peak right now in the North.
