@Luminous Lynx, yes this thread has reached the length of the human intestine by now, I'd imagine
Which is why I appreciate you taking a look in here, no easy feat really. You didn't miss much by not reading the rest of the pages, I think, so no worries.
Now, on to that thorough analysis of yours

C-IEI-Fe (Fe vs Ni vs Base type is not certain tho).

From DarkAngelFireWolf69's C-IEI DCNH:

"Emotional, charming, sociable. Gets in contact with people in an easy and laid-back way, although it is difficult for him to remain constantly in an emotionally elevated state. Attracts people with his spontaneity, sincerity and cordiality. Shares his experiences in a figurative way and with subtle humor. Able to cheer others up, to make them laugh with unusual tricks or phrases.

Routine and monotony are very poorly tolerated. Does not like stereotypes nor strict rules. Cannot live without inspiration, can’t stand regulations and instructions. Inclined to improvisation. Knows how to choose the right moment to suddenly attract attention. Gives compliments very willingly, especially to those he considers as authority. This person crafts and presents his requests in such a shape that it is very hard for others to say no."
I've been considering C or H to be my DCNH type for a while now, yes. The description is good but-- No buts, buts come at the end.

This is absolutely how You came off to me in the video, Your demeanour, Your answers, etc. You're a witty lad, but I'm not convinced that necessarily means Ne. I agree in full with other's saying You're Program N. People were typing the far calmer, far gentler, far more obviously Fi signaling ToTheMoon IEE, yet type You--the clearly more dynamic, cheeky, and piss taking--EII (again, I haven't read every page of the thread). Shit like this is why I treat VI as ancillary and not as a primary basis of typing, but I'm also not savvy enough with it to rightly criticize tbf. I think the next most probable typing is IEE-Fi and I'd put EII-Ne and Sol's suggestion of ILE distantly behind those. Aversion to ritual/routine/protocol, need for motivation, general optimism toward future achievement yet languid underachievement in the daily activity, charming warmth, etc are all present. Both IEI and IEE have 3/4D N and F, but IEI has weaker Te and Se, making a need for motivation and momentum all the more prevalent.
Now you're just preening my Feathers and making me blush and grin like a schoolgirl. I have never considered myself to be EII, no. I've flirted with the possibility of being one but that was mostly because of how many people were suggesting it as a type for so long. I thought they must be on to something, after all but no matter how hard I try, I just can't see myself as one. More so, I feel like if an LSE were here and now, they'd want to slap me because of how not-so-serious I am about Fi matters they otherwise consider as the crux of their aspiration. I'd be a huge disappointment, poor them. I do feel like a vegetable mostly. Nowadays, it's gotten so bad that I don't have the drive to even write more than 100-200 words if you don't count the forum fuckassery and messages sent to other people. Not sure how much of it is type related or mild depression (hopefully not). I'd say my Ti is below the acceptable norm and I should be publicly executed for it. Although I took a questionnaire in a socionics server once and the admin said my Ti isn't that bad which surprised me!

As a trivial aside, hypochondria alarmism can be typical of Si Super Ego. Conjectural, but Oppai told me You remind him of a younger, slightly more anxious me. I'm more intense than You (I'm a Dominant in DCNH tho, and an Sx/So Counterphobic), but our self-aware piss takey humour and rambling is comparable. I agree You look like the IEI model in VI You referenced. I'm also TR in Model G (IEI), and I'm an actual Beta NF, so this idea DarkAngelFireWolf69's IEI is an IEE isn't something to take as gospel. You're also a young lad; when I was young (raised in a Gamma-transitioning-into-Delta society) my only clear Beta Quadral values were loyalty and an expectation that people conduct themselves honourably, more or less. I also went through phases of aversion to the "church", and a number of things, and generally didn't stand out or rock the boat as much as I'd come to, once I grew intellectually. Wasn't until my early-mid 20s that I really had a clear perception of myself, of which psychology and typology assisted in no small measure. If I understood You correctly in the aside You made about Gaimann's literature--that You intend to become an author as well--right on, lad. I'll also be an author, when prudence and inspiration converge.
"Intense" is the right word to describe you. Much more hardcore than I could ever be, really
Enneagram and instinctual variant-wise, I have always been confident about being a core 4. Not sure about the wing, though. The stacking shooould be So/Sx I think, but So/Sp would work just as fine, maybe? Haven't looked into it much. Don't know anything about my head type, that's the trickiest to pin down between 6 and 7, but I'm nearly convinced that 1 is my gut-fix. I feel like a paper crane when in environments that ooze Se, really. Your, Sarcophagus and Oppai's chat the other day for example-- That was TOO much for me. Lack of interest in what was being discussed might've contributed as to why I found the convo downright...tasteless, to put it. But yes, I felt like I didn't miss much by going to tutoring in the midst of all that action

Finally, our mutual friend [taps nose] informed me that Mystical typed You IEI. Myst is arguably the most knowledgeable person I've spoken with on Socionics theory, and her instincts are superb. I've heard Y'all are friends, which came as a welcome surprise. She's a great woman. I trust in her perception more than any random VI attempt.
Mysty is amazing. I love her, as I love many other people on the forum-- A lot of people here are lovable. Myresearch, mrrrmaid, XaiXai (Xaiviay, especially her ), Ave, Adam ("daddy", Dadam), Atari/Cody/the SLI with too many names, hag is a treasure too. The only instances when I felt off in my interactions with mysty are those when I feel like my spotaneity is a bit subjugated. It leaves things flowing not as smoothly and a bit awkward at times. Of course, her demanding nature also gets me a bit isnsivnisnvdnvdilvndlivnjkvkkdkjkj at times, because I can be easily overwhelmed when being requested loots of answers and explanations in a short span of time. Two a day will do, thanks.

I feel like certain SLEs can crush me with the tip of their middle finger. I've had the (unhealthy, I admit) belief that most of the SLEs are usually not worth getting too close to as it will only lead to frustration on my part, and maybe a few internal and external crying fits on my part.
Your analysis is really good! But I don't know how I /should/ feel about it. I'm a tweeny bit inclined to still consider IEE > IEI but then the part of me that's lacking the actual Te and Se to /make things happen/ would be revolting. So I go towards IEI>IEE but then something /else/ happens. I reconsider my options, eventually contemplating the possibility of being a completely different type (EII), then go back to cycling between the two NF irrationals, like a wibbly wobbly socionics loop.

P.S - That wink You did in the video, and the delivery itself is pretty much a me ripoff
