hmm, i'd be perfectly fine with the LIE concept if few things didn't bother me. LIEs, due to
creative Ni have the tendency to think too much of the consequences and of timing of decisions, rather than actually act on them, although to a lesser extent than in the case of Ni dominants.
Similarly, LIEs are concerned with covering all possible long-term outcomes, and will often make a suggestion to do something "just in case"which leads them to do what is useful only theoretically, and not actually.if we look at rust he doesn't have a back up plan on his actions, he's highly proactive and he definitely doesn't think about the consequences.
third function - Fe- LIEs make an effort to adapt to the prevailing emotional atmosphere, especially in group situations, and try to promote a positive emotional environment, in the form of witty remarks esp. in the presence of individuals they are already somewhat acquainted with and which appreciate... hooweverrrr, this is disputable cause i'm following the "he's depressed" premise so i wouldn't take it as seriously.
i actually really like your description of his Se mobilising - but usually LIEs Se is highly motivated with either finantial gain or strictly professional but rust's truth/answers seeking imo comes from the different place- he wants to find the answers cause he wants to know the truth/restore justice.....
here ili- te fits very well imo---- 4th function Fe makes them analyze situations and make decisions in a very logical and scientific manner. Their reliance on objectivity and accumulation of factual knowledge leaves very little room for decisions based on emotional considerations. ILIs deeply dislike being asked or coerced to express their emotions. They are most comfortable expressing negative sentiments which indicate their disdain for required emotional participation.....
ya know what?
it's really hard to tell since he's clearly physically unhealthy (the depression, the ptsd) and it's difficult to analyze it properly. he really can be either.
i like your LIE variant --- made me think about his whole character concept differently
as for his variant ---- hmm i'd say he's sp last considering the lifestyle he leads ha
