Idk... There are ESI typings. I personally eliminated everything Se-ego. He is a very idealistic character deep down. I mean yeah... there could be an argument for him being ESI. He is duty oriented. ‚I’m a sworn brother of the Nights Watch‘. So idk. I mean he takes this really srsly. There is a lot of ego involved with him in this. The others are kinda more, well I’m just here trying not to get my ass killed. There was also this scene where Qhorin trolled him. Qhorin was like ‚We are the Nights Watch, we protect the realm‘ and Jon kind of looked at him and nodded. Qhorin just laughed his ass of and was like ‚dude, this is just talk, you know, to keep us warm in the night (to give all this stuff the appeareance of having any meaning). But you see with Jon it’s different, he really believes in it. So maybe that could be a way to argue for ESI. I think he is also a compliant triader, because of that.
But the things is, I just don‘t see high Se. I think he values it, but with every scene I watched, it’s like he is not really strong at it from the get go. I mean there is some hesistation in him, everytime the situation calls for some decisive action. Like when they catch Ygritte and he has to kill her. He hesistated and she picked up his hesistation and balked. He catches her and tries again, but she is like ‚we both now you don‘t have it in you‘ (or sth. like that). Stuff like this happens often with him and I think people really smell it out in him, hence Qhorin telling him ‚winter is coming‘ ‚kill the boy, and become the man‘. It’s something more along the lines, about Jon having to learn to make the hard decisions and act upon them, if he truly wants to achieve, what he aims for – ‚protecting the realm‘. But it’s not natural to him. It‘s more like he drags himself through the whole ordeal.
I think, when he becomes Lord Commander it kind of shows at times. I mean yeah he is more decisive now. Like beheading that one guy, who calls him a bastard and disrespects him. He kinda gets that in his position, he cannot let that slip. But still I think it’s not strong enough to prevent what’s happening in the end of Season 5. Idk... I can still see a point in the ESI typings. He is loyal, he is duty oriented. You could argue for Fi. But I was leaning towards weaker Se. You see that’s kinda his arc/what he has to develop. He is very idealistic deep down. 'You know nothing Jon Snow‘ is like the running joke of this show. It‘s like everytime people take a look at him, they pick this up in him, that he is more of an idealist and start to poke. In my opinion it’s really about him having to develop Se and Thinking. Which brings me to...
