at the end of the day i think the reason we’re all so obsessed w jon snow in the books is the inherent comedy of the Chosen One being sent to magical boarding school and just hating every minute of it. he’s not realizing his full magical girl potential he’s just exhausted. mans is TIRED. there’s a literal giant camping out in his front yard and he’s stressing over salt beef. there is an uber hot magical witch actively trying to seduce him and he’s just like ‘omg ygritte had red hair... im going to kms’. he is actively becoming a wolf. like straight up animorphing into his pet dog. and he doesn’t give a shit he’s like ‘hm that’s weird’ and then he gets distracted smelling satins’ hair again. easily the most character of all time. god.
"You know nothing, Jon Snow" isn't a phrase that should determine Jon's cleverness or indicate he's among the most ignorant characters.
Context is always important. When Ygritte told him this quote for the first time, he was a teen boy raised and educated in westerosi society- a society with strong prejudice against the Free Folk. So, he was as clueless about them as all the other westerosi people ( other pov characters are all included).
What truly matters is that Jon didn't remain stuck in his bias but actually observed and listened to Free Folk's perspective on things. Unlike what he was taught - that those people were savages - he came see them as fellow human beings who deserved the same protection westerosi people had ( aka the Wall protecting them from Others). Some of the people he truly admires and respects are among the Free Folk.
I know there is a notion in this fandom that Starks' views remain unchanged but Jon is a very adaptive character. He always listens different perspectives and has no problem to change his former views if he realises they were wrong. He's far from the " know nothing" stereotype of someone who is ignorant about the world and willfully continues to be so.
A quote I believe that highlights the type of person Jon is and actually has links to the original "Know nothing" Ygritte quote is this one below:
They know nothing, Ygritte. And worse, they will not learn.
personally I like to think that, amongst the nights watch slash stannis’ army when they finally get there, jon snow has a big reputation for being a whore. getting up naked in the baths and just walking out angry on alliser thorne and whatshisface while naked as his nameday. hooked up with a wildling girl beyond the wall, and now both the wildling princess and old man warrior are flirting with him like crazy in front of everyone (aka val makes barely concealed threats and tormund is constantly talking about his penis). made satin his personal assistant and the first question whatshisface has is ‘are y’all fucking.’ now alys karstark rolls up in a wedding dress and asks for jon snow personally and everyone sees them giggling together during her wedding that jon arranged? and the rizz he has is unbelievable, as sam will personally tell you
Jon discovering dying Ygritte is a very sad scene. And it gives the lovers the chance to have a final intimate moment...
...until you remember that Jon couldn't move well on his own ( with his injury) and a couple of parallels above he describes Satin not only helping him get down to the yard but also move around.
So while Jon and Ygritte have their farewell scene somewhere nearby Satin is standing looking like this:
