jon is not a hufflepuff, he's a slytherin, who maybe leans gryffindor. but hufflepuff? yeah, no
oh my god, no. no, no, no. sorry anon, but jon snow is not a slytherin. he could never be a slytherin. why would you even think that? because he’s broody and emo? or because he’s risen high in the world? those things don’t make him a slytherin. let’s break it down:
ambition: no. jon is not ambitious in the slightest. jon didn’t fight tooth and nail at any length to become lord commander, it was an honor that was chosen for him - because of his bravery, loyalty and kindness. and when he won the election, of course he was happy. but not because his selfish ambitions were somehow being fulfilled, but because for literally the first time in his life, jon had been recognized, appreciated and validated by his peers, something he never got at winterfell. and even before then, when jon worked so hard to prove himself in the training yard and longed to be a ranger and not a steward, those dreams had nothing to do with jon wanting to climb the ladder of power - he simply wanted to be recognized for his talents and skills, and once he realized what an honor it was to be the lord commander’s personal steward, he accepted the position and carried it out honorably.
after stannis arrives at the wall, he offers jon everything he’s ever wanted: a wife, winterfell, the stark name - and jon says no. because he is loyal to the night’s watch and because he refuses to usurp his sister *cough* take a hint, show!jon *cough*.
Lonely and lovely and lethal, Jon Snow reflected, and I might have had her. Her, and Winterfell, and my lord father’s name. Instead he had chosen a black cloak and a wall of ice. Instead he had chosen honor. A bastard’s sort of honor.
Jon said, “Winterfell belongs to my sister Sansa.”
if jon were ambitious, he would have taken all that stannis offered him and more. but he didn’t. jon is not ambitious.
pride: no. jon is not prideful - he is loyal. he is loyal to the stark name and to his father and siblings. it may have started out as pride in the beginning - after all, being ned stark’s son was all jon had that made him “special” in the eyes of others. but that quickly vanished when ned was branded as a traitor to the realm, but jon’s loyalty to ned did not. when jon heard that robb had taken up arms against the lannisters to free his father, jon aches to join him - and even goes as far as running away from the watch out of loyalty to his family.
If he must perish, let it be with a sword in his hand, fighting his father’s killers. He was no true Stark, had never been one… but he could die like one. Let them say that Eddard Stark had fathered four sons, not three.
but jon doesn’t get very far, because his friends come after him and remind him of the vow he made to the night’s watch, and so jon goes back to do his duty.
“Honor set you on the kingsroad… and honor brought you back.”
honestly, jon is one of the most selfless characters in the entire series. he is always putting others above himself. he was literally murdered for being selfless and honorable enough to let the wildlings through the wall so they all wouldn’t die. jon may be proud of having stark blood, and loyalty to it and to his family - be he himself is not prideful as a person.
cunning: again, no. jon is not cunning. he’s intelligent, yes, but not cunning. he doesn’t deceive or trick others at their expense or for his own gain. the word cunning literally means “having or showing skill in achieving one’s ends by deceit or evasion.” cunning ≠ intelligence. it’s a trait that requires deceit to further one’s own goals - something jon has never done.
jon isn’t a slytherin, he just isn’t. this isn’t to say that slytherins are bad or anything, because they’re not, but jon isn’t one. to say he is would be a gross misinterpretation of his character. do you know who is a slytherin? cersei lannister. petyr baelish. margaery tyrell. ramsay bolton. does jon resemble any of these characters? no, he doesn’t.
now let’s take a look at hufflepuff jon:
patience: yes. jon is a very patient person. you can see it clearly in his friendship with sam. a slytherin would never bother with someone like sam, but jon does. he helps sam, defends him, sticks up for him and even threatens to sick ghost on the members of the night’s watch who bully him. jon is exceedingly patient with sam.
loyalty: yes. jon is extremely loyal. this was covered fairly well above, but it’s obvious that jon has an enormous sense of loyalty and honor to those he loves. he remains loyal to his father and to the starks even after they are deemed traitors to the crown, and he has immense loyalty to the night’s watch as well. he is also loyal to his friends, like sam, pip, grenn and edd. it is always said that jon is the most like ned out of any of the stark children, and with this there is no exception. jon even has a loyalty to the free folk after spending so much time with them, being able to empathize with their plight. now here’s where it gets tricky: for a man loyal to both the night’s watch and the wildlings, what is he supposed to do? he did what his father would have done - the right thing, even at the quite literal expense of himself.
justice: yes. jon has a very strong sense of justice. like his siblings, jon grew up hearing ned say that “the man who passes the sentence should swing the sword.” jon has a very strong moral compass and sense of right and wrong, and he carries that out through his actions, especially as lord commander, when he beheads janos slynt for defying him, even though he doesn’t really want to. or before, when jon insists that the watch go after the mutineers who killed jeor mormont at craster’s keep, not only to serve them justice, but to keep them from spilling the night’s watch’s secrets to the wildlings. jon’s sense of justice is also what prevented him from killing ygritte. why should jon kill this woman, who hasn’t done anything wrong but exist? ned said:
“If you would take a man’s life, you owe it to him to look into his eyes and hear his final words. And if you cannot bear to do that, then perhaps the man does not deserve to die.”
in jon’s eyes, ygritte does not deserve to die, so he doesn’t kill her. instead, he falls in love (much later) and he breaks his vows, yes, because jon snow is a human being who is flawed, and craved the love and affection of another person. remember: at winterfell, jon never allowed himself to sleep with anyone because he was too terrified of fathering a bastard. how fucked up is that? give the boy a break.
hard-working: yes. jon is very hard-working. jon has worked hard for every single thing he has ever received. nothing was ever handed to jon, he had to earn it all for himself. but the thing that separates jon from slytherin characters, who work hard to further their own personal vendettas, is that jon works hard for the benefit of others. yes, jon wants to better himself too, but not for selfish goals or power - jon only wants to be recognized and appreciated, a very human thing to want, indeed.
kind: yes. listen, jon is a little sweeite, let’s be for real. let’s talk about sam again!! remember that time in agot when jon went to maester aemon secretly and begged him to make sam his personal steward so sam would stop being beaten and humiliated in the training yard?? because i do!!!! (i’d quote it here but it’s several pages long in “A Game of Thrones: Jon V” if you want to look it up). but yeah, jon could have very easily gotten in serious trouble for going to maester aemon, but he did it anyway because he couldn’t bear to watch sam suffer any longer. as a child, jon was always very kind to all his siblings (especially robb and arya) as well. and even though jon was often jealous of robb, he never resented him and always loved him.
these are just some examples of why i think jon is a hufflepuff and why he is definitely not a slytherin. jon definitely has some gryffindor traits as well (bravery, daring, chivalry), but i think at his core he is a hufflepuff, like ned.
